Today in this podcast, Matt and Erin talk about a new publication summarizing insecticide evaluations for soybean aphid. The Yellow Book for soybean aphid starting in 2005 in response to a growing demand to manage this invasive pest. Matt was up for the challenge and passed the torch to Erin in 2009. Now the evaluations are at 2 ISU Research Farms and include 25+ treatments annually. You can access all the Yellow Books FREE on their lab website: http://www.ent.iastate.edu/soybeanresearch/content/extension.
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.
