Blue mold did not occur in test plots and Blue mold did not occur in test plots and incidence in the Kentucky was very low. incidence in the Kentucky was very low. Black shank was the worst it had been in Black shank was the worst it had been in three years. Drought stress added to the three years. Drought stress added to the problem by reducing the uptake of Ridomil problem by reducing the uptake of Ridomil or Ultra-flourish and by adding stress to or Ultra-flourish and by adding stress to black shank resistant varieties.

Alfalfa burn down testExperience has shown that eradicating an established alfalfastand to plant no-till tobacco can be challenging. This studywas conducted on an approximately seven year old stand ofalfalfa. Treatments included fall and spring application of round-up with and without a broadleaf herbicide (Clarity). Contrary to previous studies the spring treatments appearedto be more effective for eliminating alfalfa. Work willContinue to identify effective means of controlling alfalfaprior to planting no-till tobacco.
