Abstract:
|
This DVD discusses the need to develop insect control methods without chemical contamination in export products. These include sealed silos and knockdown fumigants. The best fumigant is phosphine. However, weevils have developed a resistance to this mainly due to silos not being properly sealedwhen the phosphine was used. This DVD shows features to look for when buying a sealed silo and how to maintain, check and test the silo before harvesting.
