Description: 

It seems like a long time since the last episode and that's because it was! Matt and Erin are back to talk about pest updates in Iowa. Drought stress throughout much of the state has been ideal for twospotted spider mite. Erin reports Some injury has been observed in corn and soybean this summer. Treatments are going on now throughout some southern Iowa counties. In addition, soybean aphid continues to be an erratic pest. Some populations are building up in northern Iowa counties, but most fields are not reaching the economic threshold in July. Matt elaborates about high numbers of Japanese beetle and they talk about the use of pheromone traps as a management tool. Finally, Matt talks about a new Science research paper that has inconsistent data on the effect of neonicotinoid seed treatments on wild and managed bees in Europe.
