Pathogen & Nematode Management

Pathogens, those infectious organisms that reduce crop yield and/or quality, must be managed to reduce the damage they cause to levels that do not affect farmers’ profitability, but with an eye to maintaining environmental and human health. Alternatives to pesticides, better use of pesticides, and use of better pesticides (less toxic, targeted specifically to pest, lower effective rates, etc.) are all options to increase sustainability.
