EVAL TM FOR FUMIGATION FILM

EVAL TM FOR SILAGE FILM

What is fumigation?

and

Why need EVAL?

Fumigation is needed for “Kill disease or weeds”

Disease increase by continuous cropping/grow same crop and same area continuously.

For efficient farming

bacterium Nematoda

Fumigants

Fumigant Risk Status

Methyl bromide ozone layer destruction Decided full phase-out untill Y15 by Montriol Protocol.

Chloropichrin strong tear gas/smell Increasing as alternative. Developed by Nazi as wepone.

Dichloropropene carcinogen Increasing as alternative.

Fumigant Methyl bromide
