Description: 

Don't drought this episode was a good one. Matt shares an update on the Iowa drought and encourages people to use the U.S. Drought Monitor as a tool to measure landscape moisture levels. Matt and Erin transition and talk about pest activity around the state, starting with twospotted spider mite. Erin wrote a recent ICM News article that talks about scouting and managing this pest that favors hot and dry conditions. Spider mites can be first detected around field perimeters and then eventually infest the field interior. Discoloration, webbing and stunted plants are often the result of heavy spider mite feeding. Erin mentioned a new miticide, AgriMek, that has promise for suppressing mites in corn and soybean; find the label here. The conversation switched gears to talk about some corn silk clipping pests, like Japanese beetle and corn rootworm adults. Scouting to determine pest densities and potential interference with pollination is important. Learn more about Japanese beetle ID, scouting and management with an ICM News article

Description: 

In this episode, Matt and Erin talk about managing twospotted spider mites in soybean. Considering other pests is important, given the non-target effects with an application. This is particularly true if soybean aphid is in the field because of recent reports of pyrethroid resistance. They discuss options, including using miticides to suppress mite populations. Implications of pest ecology and economics plays a part in managing soybean pests.
