A New Bean Leaf Beetle Threshold Calculator is CreatedIntegrated Crop Management News
AbstractIn April, an ICM News article predicted a slightly higher winter survivorship of bean leaf beetle in Iowa. Not surprisingly, this summer I have been hearing about a few soybean fields with bean leaf beetle. Most reports of overwintering and first generation beetles are at low densities with negligible defoliation. There are two generations of bean leaf beetle in Iowa (Fig. 1), with the second generation emerging in a few weeks. Scouting for bean leaf beetle and other defoliators should continue until seed set.
