Research Notes: Interactions of cultural practices with insect-induced stress on soybeans

Numerous reports exist which characterize yield loss and defoliation relationships. Management guidelines and decisions regarding defoliating pests have been based largely upon findings from one or more of those studies . The use of such studies as decision-making criteria may be limited since most defoliation yield-related research has been conducted in the Midwest with varieties , growth habits and environmental conditions widely divergent from those found in other areas of production
