II. Introduction (Limit 1 page)
OBJECTIVE: Our objective is to provide a natural and effective treatment for fire blight through the use of bacteriophages. Bacteriophages are viruses that infect bacteria. They are the most abundant organism on the planet and are essential to maintaining ecological balance due to their ability to infect and kill their hosts. The term bacteriophage literally means “to devour bacteria” as they infect their host organisms by injecting their DNA, pirating cellular machinery to produce progeny, and finally lysing the host cells to release tens or hundreds of progeny that then infect more bacteria. These natural predators are highly specific for their host organism and thus do not affect humans, plants, animals, or the environment. Bacteriophages are biodegradable and considered “organic,” making them a valuable ally in the fight against agricultural diseases. Bacteriophages are commonly used to treat several agricultural diseases, including those that infect tomatoes and peppers, in the United States and abroad. We have isolated 41 bacteriophages that infect and kill the causative agent of fire blight. These bacteriophages have been isolated and amplified from local orchards in Utah. We have combined the best five bacteriophages into a natural bactericide named Fire Quencher. This proposal outlines our goals to 1) further characterize these bacteriophages, 2) conduct small-scale efficacy tests of Fire Quencher in controlled green houses, 3) produce characterize and compare liquid and solid Fire Quencher for large-scale distribution, and 4) test the efficacy of Fire Quencher in conjunction with apple orchards. DESCRIPTION OF DISEASE: Fire blight is a bacterial disease that affects a wide variety of plants including apple trees, pear trees, cherry trees, rose bushes and chrysanthemums. Reported apple produce losses due to fire blight are in excess of $100 million annually in the United States alone ((Norelli et al., 2003). Fire blight is caused by the gamma-proteobacterium Erwinia amylovora that invades wounds on trees and infects almost all tissue types, including flowers, stems, and leaves (Vanneste, 2000). Because the bacteria can overwinter within the bark of tree limbs 2-years-old and older, infected branches often serve as the reservoir of bacteria in subsequent seasons (Khan et al.).. Infected leaves bend inwards towards the stem, release infectious exudates, wilt, and die. As dead plant matter falls to the ground the bacteria can also subsist in the soil. Since the bacteria prefers to amplify in newly formed plant tissue, spring blossoms and new shoots of

infected trees suffer the greatest damage. Death of blossoms, leaves and shoots, results in low fruit yields and smaller fruits.
The current primary treatment for fire blight is the antibiotic streptomycin sulfate. Other treatment options include heavy metals (such as copper), and Blossom Protect (a new yeast-based spray); however, both of these non-antibiotic options can cause russet. All of these options are considered preventative since none are very effective after symptoms of fire blight appear. Once symptoms appear, trees are generally remove from the orchard to prevent spread. Thus, treatments are currently used at blossom time.
JUSTIFICATION The need for an alternative form of fire blight control is imperative as bacterial resistance to antibiotics and heavy metals has increased (Martinez et al., 2009b). In addition, many farmers would prefer to decrease the use of antibiotics and heavy metals in agriculture (Lipsitch et al., 2002; Martinez, 2009; Martinez et al., 2009a; Stockwell and Duffy, 2012; Stockwell et al., 2011) and still maintain healthy, productive crops. The goal to eliminate antibiotic use is especially important since most Erwinia amylovora strains isolated from orchards have developed antibiotic resistance (Ngugi et al., 2012). For fire blight, antibiotic and heavy metal use, as well as the associated development of resistant bacteria is particularly alarming because Erwinia amylovora is closely related to E. coli and Salmonella and may thus be able to transfer antibiotic and heavy metal resistance gene cassettes. For organic farmers, an alternative option is imperative because antibiotics will no longer be allowed beginning fall of 2014. III. Experimental Plan (Please limit this section to 10 pages)
Proposed experiments: The numerical list of treatments below corresponds to experiments outline in this table.: All tests of Fire Quencher efficacy will be performed with Fire Quencher alone or in combination with streptomycin sulfate, the current standard treatment for fire blight prevention. Experiments are designed with streptomycin sulfate only controls when necessary.

2. What crops or sites will this study be conducted on?
Treatments #1-14 will be performed in a quarantined green house owned by Brigham Young University. We currently are growing hundreds of apple seedlings and 40 young trees (3 years old) for these studies. Treatments #15 -17 will be performed at both the Washington State University and the Oregon State University on test orchards that have been designed and USDA approved for the testing of fire blight treatment options. These facilities have tested antibiotic, heavy metal, and various natural product treatments (including combined treatments) the past five years. Please see their letters of support. Old red delicious trees are used which are resistant to fire blight.

3. What experimental design will be utilized?
Treatments #1-14 will be performed in a quarantined green house owned by Brigham Young University. In addition to the Fire Quencher treatment, water will be used as a negative control. The studied will be blinded in that each plant will be given a number, plants receiving the control or Fire Quencher will be chosen randomly, and different students will be used to infect versus score efficacy. Plants will be scored based on degree of disease, scores will be averaged and reported as percent infected relative to wild type. A students T test will be applied to determine validity of the efficacy. In trial tests (see Appendix 3- Supporting Preliminary Data) 100% of plants infected with Erwinia amylovora died. Thus we are confident that our numbers will provide statistical significance if our treatment provides 10% efficacy for treatments #1-10 and 20% efficacy for treatment #11-14. Scales for scoring disease are reported below. Treatments #15-17. These experiments are performed by experts Ken Johnson (Oregon State University) and Tim Morris (Washington State University). Four trees will be treated at each time point for a total of 16 per treatments. Only 50 blossoms are inoculated per tree. Evaluation is based on the number of blossoms displaying fire blight our of each of the 50 flower clusters. The diseases does not spread further into the tree since old red delicious trees are used which are resistant to fire blight spreading from the blossom. Their experimental set-up has proven to detect efficacies as low as 20% (Stockwell, 2011). All data is reported as percent trees rescued and is compared to the untreated controls and is analyzed by a Bayesian approach (Mila, 2011).
4. How many locations (field or greenhouse)? How many replications? Treatments #1-14 will all be performed at the Brigham Young University Life Science Greenhouses. Treatments #1-10 include 30 plants each (300 total), treatments #11-14 include 10 trees each (40 trees total). Treatments #1-8 will be replicated once several months apart to ensure reproducible. This replication will increase the total number of apple seedlings (2-4 inch plants) to 540 plants. Treatments #15-18 will be performed once at two separate locations, Washington State University and Oregon State University. These treatments include a total of 20 trees each, or 1/5 of the acre devoted to each study at each location for a total of 120 trees or 1.2 acres.
5. Describe how this proposal is designed to provide information on how it fits into an integrated pest management program.
Fire Quencher is designed to be an early season treatment. Optimally, it will be applied prior to plant blooming to reduce the occurrence of fire blight symptoms. All experiments (Treatments #1-18) are designed to test phage treatment prior to the appearance of fire blight symptoms, which is generally 4-10 days post infection. Efficacy will be determined by the occurrence of fire blight symptoms in treated versus untreated samples. Every type of experiments includes treatment alone and in combination with streptomycin sulfate. Streptomycin sulfate alone generally has an efficacy rate of ~87% in controlled environments (Tim Smith, unpublished data. Please see his letter of support). Note that this efficacy rate is dramatically lower in most orchards due to antibiotic resistant bacteria in the environment.

6. Data collection – Treatments #1-14: Data will be collected based on visual efficacy. A rating scale of 1-7 will be used for each sample in treatments #1-10. For treatments #1-10, samples will be evaluated each day following inoculation up to 14 days. For treatments #11-14, samples will be evaluated for 4 months to determine if Fire Quencher delays onset of the disease in trees. Samples will be compared to a control sample that was sprayed with water or streptomycin sulfate only. Standard statistical analysis will be performed (students t-test). In addition, we will attempt to isolate the pest (Erwinia amylovora) from each sample including the controls each day of the experiment by swabbing the infected area of the plant and plating to CCT plates that are semi-selective for Erwinia amylovora. Arising colonies will be verified as Erwinia amylovora isolates by amplifying regions of DNA specific to Erwinia amylovora via colony Polymerase Chain Reaction (PCR). Rating Scale:
1- No appearance of disease. 2- Leaves appear dry and shriveled but maintain normal coloring. 3- Leaves are dry, shriveled and are turning brown/black. 4- Leaves are dry, shriveled, are turning towards the stem and are brown/black 5- Leaves are dry, shriveled, are turning towards the stem and are brown/black, stem of plant is discolored 6- Leaves are dry, shriveled, are turning towards the stem and are brown/black, stem of plant is discolored and plant has ooze that exudes from cankers. 7- Plant is dead (entire plant is discolored and dry, all leaves and stem and brown/black).
Treatments #15-17: Data will be collected throughout spring/summer and times of disease appearance will be recorded to determine in Fire Quencher delays onset (suggesting multiple treatments may be necessary). For each tree, 50 blossoms will be infected with the Erwinia amylovora and each of the 50 scored for blight (color/withering) of the blossom (times 4 replicates) Old delicious trees are used since they are resistant to fire blight. The disease doesn’t travel very far into the wood before it stops.
7. Describe the pests to be controlled, the degree to which they are a problem in your state or region and the frequency that they occur (season long problem, every year, every few years).
The pest to be controlled is the gram-negative bacterium Erwinia amylovora, the causative agent of fire blight. Reported apple produce losses due to fire blight are in excess of $100 million annually in the United States alone (Norelli et al., 2003). The development of alternative treatment strategies for fire blight is imperative to protect the 5,710 acres of fruit bearing trees valued at 16.7 million in utilized production in Utah. There are no reported statistics for the frequency of fire blight in Utah, however when we called 18 local orchards along the Wasatch front all but one orchard was experiencing an infection of at least one tree in their orchard this year. Fire blight generally originates in the spring when the plant is blossoming. Insects carry it from plant to plant. It may also originate later in the season due to natural damage to the tree and/or pruning. It is a problem every year, however, the degree of the problem varies with weather conditions. Surveys of the fire blight pathogen in Utah County have demonstrated variable rates of antibiotic resistance from 10% to 90% (DG
5E
13
Aston, Utah State University). Washington State University reports a majority of Washington State Orchards infected with antibiotic resistant bacteria (as much as 70%)(Ngugi, 2011).
8. Will the crop be inoculated with the target pest or otherwise be brought into the test system to ensure that it will be available for evaluation? If not, describe the frequency of occurrence.
Yes, in each treatment #1-17 the plants will be inoculated with Erwinia amylovora. For treatments #1-14 the plants will be inoculate by scoring the underside of a leaf and rubbing a 108 culture of Erwinia amylovora over the wound. For treatments #15-17 trees will be inoculated by applying directly to the 50 blossoms per tree.
9. What is the proposed start date and completion date? Also describe this in chronological order in the context of the experimental plan.
In all, are goals are to: 1) further characterize the 41 Erwinia bacteriophages we have isolated through DNA sequencing and phage host specificity, 2) conduct small-scale efficacy tests in controlled greenhouses, 3) produce, characterize and compare liquid and solid Fire Quencher for large-scale distribution, and 4) test the efficacy of these solutions in conjunction with apple orchards. All tests of Fire Quencher efficacy will be performed with Fire Quencher alone or in combination with streptomycin sulfate, the current standard treatment for fire blight prevention. February - April 2014 Goal #1) Further characterize the 41 Erwinia bacteriophages. DNA sequencing and host range specificity of Erwinia phages will be completed. DNA sequencing results and analysis will verify our current data on whether the phages are lytic or temperate. Lytic phages simply infect their host and produce progeny through lysis and destruction of the host cell. These are desired for agricultural treatment. Temperate phages are able to infect a host and integrate their DNA into the host genome. They can lie ‘dormant’ until awakened by an environmental cue such as stress. Temperate phages are not desired. Temperate phages can be identified in the lab (see appendix) and verified by DNA sequencing because phage that are lytic should lack the DNA encoding for proteins necessary for integration into the host genome. DNA sequencing of entire phage genomes is relatively expensive so we have requested support for this analysis. Our research team has a combined total of 14 years of experience with phage isolation and characterization including DNA sequencing and analysis (see Appendix 3, Supplementary Preliminary Data). Host specificity tests are important for testing the safety of our phage. Host specificity tests have been performed for 13 of our 41 phage. These phage were tested for their ability to infect close relatives of Erwinia amylovora, the bacteria E. coli and Salmonella. None of the 13 phages were able to infect either of these hosts. We are in the process of testing the remaining 28 phages. In addition, we have tested for deleterious affects of Fire Quencher on healthy apple seedlings and have seen no negative affects.
Goal 3) Produce, characterize and compare liquid and solid Fire Quencher for large-scale distribution. Studies will be conducted on the stability of bacteriophage solutions for long-term use. Specifically, bacteriophage will be stored at room temperature and in the fridge in various solutions (nutrient broth versus a saline buffer) and analyzed each week for plaque
5E
14
forming units (viable bacteriophage). In addition, bacteriophages will be lyophilized using standard procedures (Paupermpoonsiri et al, 2010), and resuspended at one month intervals to determine phage viability. These tests will be initiated February and will continue through April. High quantities of bacteriophages are currently being produced successful to begin these tests on our target date. February 2014- December 2014 Goal 2) Conduct small-scale efficacy tests in controlled greenhouses. Treatments #1-14 will be performed to test efficacy of Fire Quencher Treatment of apple trees. Efficacy will be determined alone and in combination with streptomycin sulfate, the current standard treatment for fire blight prevention. Experiments #1-8 will be replicated, initiated in February and again in July to test reproducibility several months apart.
March 2014- August 2014 Goal 4) To test the efficacy of these solutions in conjunction with apple orchards. Treatments #15-17 will be performed. Efficacy will be determined alone and in combination with streptomycin sulfate, the current standard treatment for fire blight prevention.
10. Describe the test facilities where these studies will be conducted.
Treatments #1-14 will all be performed at the Brigham Young University Life Science Greenhouses. This facility includes 12 wings, each 30 x 125 feet, including one quarantined facility that we will use. For a full description of this facility please visit: http://lsmagazine.byu.edu/Issues/Spring2012/LifeSciencesGreenhouses.aspx Treatments #15-17 will be performed once at two separate locations, Washington State University and Oregon State University. Each location is a one acre test orchard run by qualified fire blight investigators funded by the USDA. Letters of support and contact information for each of our collaborators is provided.

11. Budget: Provide an itemized budget, with categories such as labor, supplies, travel, etc. Provided below (see Appendix 7).
12. Describe why this product is needed and why growers are likely to use this product. (Also list alternative conventional and alternative biopesticide treatments)
The need for an alternative form of fire blight control is imperative, as bacterial resistance to antibiotics and heavy metals has increased dramatically in recent years with 10- 90% of antibiotic treatments proving ineffective at preventing disease. Recent data have proven antibiotic and bacteriophage combination therapy effective in the treatment of a variety of diseases (Knezevic, P., 2013, Chhibber, S., 2012; Kirby, AE,2012; Zang, Q.G, 2012). In addition, for organic farmers, an alternative option is imperative because antibiotics will not
5E
15
longer be allowed beginning fall of 2014. Fire Quencher is a natural, bacteriophage-based biopesticide amplified from the environment. It is safe, biodegradable, easy to apply by conventional methods and proven to be extremely effective at destroying the causative agent of fire blight (Erwinia amylovora) in the lab. If we are able to show efficacy in orchards through this study, alone or in combination with antibiotics, the product will be widely received.

APPENDIX 3 - Supporting preliminary data
Phage Isolation Between Fall 2009-Spring 2013 the BYU Phage Hunters program has captured and isolated over 55 phages, sequenced 52 of the phages and published 20 of the sequences. Figure 1 is an example of a control plate with bacteria and a test plate of bacteria with exposure to a phage sample. Clear ‘plaques’ indicate an area where a phage has landed on the plate and devoured the bacteria. As the phage produce more progeny this clearing spreads radially through the plate.
Figure 1. Bacteria are grown on the surface of agar in a dish to generate a ‘lawn” of bacteria (A). when phage is added to the plate, clear plaques indicate where phage have infected and killed the bacteria (B).
Prior to this spring, only a single phage was isolated that infects Erwinia amylovora . As phage isolation conditions were optimized, the BYU Phage Hunters Program has isolated 40 more this spring, summer and fall bringing our library total to 41 phages that infect Erwinia amylovora. Electron micrographs of each of these phages have been taken, one DNA genome has been sequenced, and all 41 bacteriophages have been grown to a concentration of at least 1010.

Phage Characterization
Lytic vs. Temperate Phage. There are two basic types of phage lifestyles, those of lytic phage and those of temperate phage. Lytic phages simply infect their host and produce progeny through lysis and destruction of the host cell. These are desired for agricultural treatment. Temperate phages are able to infect a host and integrate their DNA into the host genome. They can lie ‘dormant’ until awakened by an environmental cue such as stress. Temperate phages are not desired. Temperate phages can be identified in the lab through close inspection of the plaques produced by phage. Lytic phage produce a clear plaque of killing whereas temperate phage produce a turbid plaque since they can integrate into the host genome instead of lysing the host (Figure 3). Only one of the 41 bacteriophages that infect Erwinia amylovora appears to be a temperate phage. These results will be validated by whole genome DNA sequencing of all 41 bacteriophages. The bacteriophages that are temperate should contain DNA that codes for proteins necessary for the temperate lifestyle (proteins for integrating DNA into the host genome, etc.). Characterization of all 41 bacteriophages is desired so that we can use the more lytic and stabile in our fight against fire blight.
Figure 3. The plaque appearance is indicative of the phage’s ability to enter lysogeny. Lytic phage produce clear plaques (A) and lysogenic phage produce turbid plaques (B)
Bacteriophage Stability. Of the 41 bacteriophages, 12 we isolated by June of 2013. These 12 phages have been stored at a concentration of 1010 plaque forming units/mL (pfu/mL) for six months and have not lost titer. We will be conducting stability tests of all 41 phages in this study, but our initial results are encouraging.
DNA isolation. Of the 41 bacteriophages, we have successfully isolated DNA for 28. This DNA is of sufficient quantity and purity to ensure high quality whole genome sequencing as assessed by DNA gel electrophoresis (Figure 4).

Figure 4. Purified whole genome DNA isolated from six bacteriophages that infect Erwinia amylovora. The DNA appears as a solid, bright, single band of appropriate size (lane 1 is a DNA size standard ladder, lanes 2-7 is genomic DNA isolated from six different bacteriophages).
Phage Safety Studies
Bacteriophage Specificity Tests. In order to ensure the safety of our bacteriophages, we have tested their ability to infect closely related bacteria, E. coli and Salmonella. No bacteriophage has ever been isolated that infects bacteria that are very distantly related, for example, no bacteriophage can infect gram-negative and gram-positive bacteria, however some have a broader host range than others. We desire bacteriophages that have a fairly narrow host specificity, broad enough to infect different Erwinia amylovora hosts but narrow enough to be unable to infect closely-related bacteria of a different genus such as E. coli and Salmonella. To perform these studies we have collected over 30 strains of Erwinia amylovora from Utah and obtained a strain from Canada. In addition, our collaborators Tim Smith and Ken Johnson are sending us strains from Washington and Oregon to expand our library. A variety of E. coli and Salmonella strains were obtained form Professor John Roth (UC Davis). We conducted host specificity test for 13 of the 41 phages using a three Erwinia amylovora strains, and two E. coli and two Salmonella strains. All 13 of our phages were unable to infect E. coli and Salmonella. Thus our bacteriophage have a high specificity for Erwinia amylovora and should not harm any other organism whether it be bacteria, plant or animal.
Fire Quencher Safety Tests. We have tested Fire Quencher for safety by spraying 100 mL at a concentration of 1010 onto ten apple seedlings. Apple seedlings appeared unaffected and remained healthy after treatment for the duration of the study (10 days) post treatment.
Figure 5. Healthy apple seedlings treated with Fire Quencher appear identical to healthy untreated apple seedlings for the duration of the study. Pictures were taken at day five. Treated (left tray), untreated (right tray).

Production of Fire Quencher
Fire Quencher was produced by combining five of our most potent and lytic phage at equal concentrations to a final concentration of 1012 in spent nutrient broth (Difco). Because these phages were isolated and amplified from the environment by culturing in Erwinia amylovora, special precautions are taken to ensure the final product does not contain the pest, Erwinia amylovora. Specifically, cultures are centrifuged at high speed (10,000 x g) for 20 minutes, the supernate is treated with chloroform to eliminate any remaining bacteria, and the sample is then filtered through a 0.45 uM filter as a third precaution. Lysates are then streaked to NB to confirm the absence of bacterial growth.
Preparing for Trials in Apple Seedlings
We have tested our ability to infect apple seedlings with Erwinia amylovora. Thus far we have infected 12 apple seedlings with the bacterium by scoring the underside of a leaf at the vein and rubbing an overnight culture of Erwinia amylovora into the wound. All (100%) of the 12 infected apple seedlings were dead within five days. This novel method for testing fire blight treatments allows for testing large numbers in controlled/quarantined green houses without the lose of valuable trees.
Conclusions of Preliminary Data
Our preliminary data includes the isolation and partial characterization of 41 bacteriophages that infect Erwinia amylovora, the causative agent of fire blight. Our characterization of these bacteriophages indicates that they are highly lytic, reaching concentrations of 1012 pfu easily and forming clear plaques. In addition, we have performed tests on the safety of 13 of these phages by determining if they infect closely related bacteria, which they do not. They also do not affect the health of apple seedlings after four treatments at high concentration. Five of these phages were used to produce our product “Fire Quencher”, a mixture of Furthermore, we have demonstrated the ability to infect apple seedlings with Erwinia amylovora. These infections resulted in 100% of the plants showing a level seven infection (the highest rating on our scale). Together, our preliminary data suggests that we have produced a highly potent, safe, natural biopesticide that is ready for early stage testing on apple trees.

Principal Investigator: Julianne H. Grose Assistant Professor of Microbiology and Molecular Biology 751 WIDB Brigham Young University Provo, Utah 84602 Co-PI’s: Sandra H. Burnett, Ph. D., and Donald P. Breakwell, Ph. D. Dr. Julianne Grose obtained her Ph.D. in 2003 under the direction of Dr. John Roth, a respected Salmonella geneticist who studies many aspects of Salmonella and bacteriophages that infect it. Erwinia is a close relative to Salmonella making many of the experimental approaches and scientific designs similar. Dr. Sandra Burnett and Don Breakwell have been conducting research on bacteriophage since 2009 when they joined the national research project established by the Howard Hughes Medical Institute (HHMI). In 2010 Dr. Julianne Grose became actively involved with this research team and initiated the project to isolate bacteriophages that infect Erwinia amylovora in 2012. Dr. Grose has a USDA permit (PPQ 526) for the transportation of and use of Erwinia amylovora (Application number P526-‐120612-‐015). None of the PI’s have experience with EPA approval or bringing a product to market. Thus, we have joined with experienced researchers Tim Smith (Washing State University) and Ken Johnson (Oregon State University) to obtain the necessary efficacy data. Letters of support from these collaborators are attached. In addition, we are working with Ben Miller and Eric Peery, MBA’s with experience in entrepreneurship. No funding is currently available for these studies. IR4 support would help to bridge this gap between these PI’s and persons experienced with efficacy testing as well as bringing products to market.

Utah State University PERSONAL STATEMENT The main focus of my research is to identify new bacteriophage, including isolation, whole genome sequencing, and genome comparison work. I am one of three faculty members to run the Phage Hunters program established through a grant from Howard Hughes Medical Institute in 2009. Our program includes approximately 20 undergraduate students per year. Students isolate and purify phage, and prepare DNA extractions for sequencing. Samples are sequenced and the students verify assembly and perform genome annotation for submission to GenBank. Since 2009, our students have isolated and sequenced the genomes of over 55 unique phages, published 20 whole phage genomes with more to come. The Phage Hunter program provides an opportunity to pursue phage isolation and characterization for future phage therapy against pathogenic bacteria.

A Summary of Recent Results in Fire Blight Control Product Efficacy Trials
Timothy J. Smith, Washington State University, September 14, 2011
Overview: Fire blight is a bacterial disease that may attack apples and pears under certain weather conditions when flowers are present on the trees. For the disease to occur, a series of unusual events must occur in proper order:
The bacteria Erwinia amylovora must be present nearby, usually oozing from an active canker carried over from last season’s infections.
These bacteria must be transported from the oozing canker to the stigma surfaces of open flowers, usually by flies or pollinating insects.
Warm temperatures must occur, with sufficient warmth to allow the bacteria colony to grow rapidly to large numbers on the stigma.
The blossom then must be gently wetted, which allows the bacteria to be washed, or to swim from the tip of the stigma where they were growing, to the nectaries, which provide them the necessary open entry into the tree.
The bacteria that have gained entry into the highly susceptible young fruitlet must then find growing conditions to their benefit, allowing them to grow rapidly and overwhelm the flower tissues, leading to infection. Once the infection of the flower is successful, the bacteria move out of the flower into the other uninfected flowers of the cluster, into the fruit spur, and then beyond into the young wood of the tree. Within 10 to 30 days of initial infection, the damage appears on the tree as a “strike.” By this time, the bacteria are moving symptomlessly throughout the host tree, and may cause further damage to distant structures, such as shoot tips or sensitive rootstocks.
There are key points of this infection process that can be managed in the effort to prevent infection, or reduce damage to the host tree or orchard. First point, the presence of blight bacteria: Sanitation of the neighborhood is the most important step in control. Fire blight is very difficult to control if there are active cankers nearby, providing a constant source of high numbers of blight bacteria. The higher the number of live active cankers, and the closer they are, the higher the difficulty of control. Control of blight depends on the identification and removal of as many of these active cankers as possible. This is not easy, but a careful inspection and sanitation effort should be carried out prior to the normal pruning of the orchard. Blight cuttings can then be removed from the orchard prior to being intermingled with the non-‐infected pruning wood. Second point, the transport of bacteria to the blossoms: Efforts to reduce infection by controlling insects that visit blossoms have never been successful. Third point, warm temperatures and bacterial multiplication: Erwinia amylovora bacteria multiply best on the flowers’ stigma surfaces, using the same food and moisture resources that the pollen needs for germination and growth. The multiplication rate of the bacteria is dependent on moment by moment temperatures. The average temperature of the day is an outdated rough way to estimate bacterial growth rate. Totaling hourly temperature related to bacterial growth rate values over the time that the flowers are open is more precise. Fire blight infection risk models should serve as a method to
5E
determine when an infection is likely in the near future, or if infection has occurred during the current day. (See “CougarBlight 2010” for the recommended blight risk model, or WSU DAS.) If the infection risk forecast indicates infection conditions are possible in about three or four days, the flowers may be protected during the days leading up to that infection with products that retard the development of the blight bacteria that may be trying to grow on the blossoms. Most non-‐antibiotic products must be used this way. The “biological” fire blight control products are often living microorganisms, and are most effective if they are placed in the newly opened flowers soon after they open, in time to allow them to establish prior to the introduction of blight bacteria. Antibiotic or copper sprays used during this same time can hinder the development and effect of the “biologicals.” The fourth point, wetting of flowers: The actual infection event occurs when the blossoms are wetted by rain, dew, or light irrigation. If the infection risk model you trust indicates that infection conditions have occurred within the past several hours, and, especially if you believe that active cankers may be near your flowering orchard, antibiotics are the only effective treatment to reduce the degree of infection when sprayed at this timing. The antibiotic must be applied within 24 hours before or after the infection event to be most effective. The antibiotics act directly against the blight bacteria in the nectary by stopping their growth and multiplication. It is possible that the yeast product applied in the days prior to the infection event acts against the blight bacteria by changing the pH and sugar content in the nectary, and when the blight bacteria arrive, they don’t have the conditions or resources necessary to grow. The fifth point, infection occurs and the strikes appear: Nothing good happens after this point. Once blight appears, the degree of damage depends on the age and cultivar of the orchard host, and the relative number of blight strikes per tree or acre. In a young apple orchard, or a pear orchard younger than 15 – 20 years, immediate cutting of blight strikes usually leads to a reduction of total bearing surface removal. However, the blight often continues to occur during the season, and the blight manager often believes that the blight cutting is ineffective. It is best to put extra management resources into prevention, rather than reaction to this disease. Products used for prevention of blossom infection: Over the past decade, the author has tested numerous products and mixtures to assess their effect on fire blight infection. The results are summarized below. The data was developed using standardized evaluation methods that assure high levels of infection in the untreated check, and the “percent control” comparison should not be used as a direct indication of field results under natural infection conditions. To overcome the variability of natural infections, the test trees were all inoculated with high numbers of blight bacteria at full bloom to assure an even dose of bacteria per flower. In practice, products that control the infection of inoculated flowers at about 65% and above, if properly applied, will perform very well in the orchard under natural conditions. Most of the products have specific application requirements, and if correct rate and timing are not followed, are not likely to perform as in the trials. You may notice that results from the same product vary from year to year. This is likely due to variations in weather and degree of successful inoculation, rather than variation in dependability of the tested product. Generally, the various antibiotics have performed better than the other substances, and have been much easier to apply, as most other products require multiple applications prior to the infection period. However, there have been recent results with products that compete with the antibiotics for level of control.

December 9, 2013 Dr. Michael Braverman IR-4 Project Headquarters 5000 College Road EastSuite 201 W Princeton, NJ 08540-6635 Dear Dr. Braverman, Please accept this letter of support for the IR-4 grant proposal submitted by Dr. Julianne Grose of Brigham Young University entitled, “A Natural Treatment for Fire Blight: Pilot Tests in Apple Orchards.” This project has received financial support from our department for the past four years, and we are enthusiastic about its progress and potential. We are glad to learn about the IR-4 funding mechanism because this project is rapidly approaching the point at which it will require EPA approval, and Brigham Young University has no institutional experience with or support system in place for navigating the EPA approval process. The IR-4 grant would be most helpful in that regard. The phage-based treatment for fruit tree Fire Blight being developed by Dr. Grose and her collaborators, Dr. Don Breakwell and Dr. Sandra Burnett, is potentially very valuable for combating diseases in fruit tree orchards while also decreasing the use of chemical toxins that pollute the environment. Our departmental commits to continue supporting this project, as we have done for the past four years, by supplementing the IR-4 funding as follows: we commit a $3,000 match toward DNA sequencing costs, a $1,000 match toward travel, and a $11,000 match toward supplies, for a total of $15,000. This proposal addresses a widespread problem in a novel and creative way, and it fits well within the scope of the IR-4 funding mechanism. I support it without reservation. Respectfully yours,
Laura C. Bridgewater, Ph.D. Chair, Department of Microbiology & Molecular Biology
