ABSTRACT
Criteria for commercial control of vegetable diseases For commercial agriculture, the practical disease management options that ultimately are deployed must meet four main criteria. Management steps must first of all be effective at achieving commercially acceptable levels of control. Some disease control options may reduce disease severity and incidence, or result in the death of pathogens. However, if such effects do not result in vegetable crops that have commercially acceptable levels of yield and quality, that disease control measure will not be practical for the farmer.
