Biocontrol of Sclerotinia stem rot in soybeans with Sporidesmium sclerotivorum

1999 , Martinson, Charlie , Yang, Xiao-Bing , Leopold Center for Sustainable Agriculture

Sclerotinia stem rot of soybeans (also known as white mold) is caused by a soil-borne fungus and has become a serious problem in northern Iowa. Another fungus, Sporidesmium sclerotivorum, acts as a parasite of the sclerotia and this research tested whether this mycoparasite could act as an effective deterrent to the soybean stem rot pathogen.

Integrated pest management for wireworms

1999 , Pedigo, Larry , Rice, Marlin , Batchelor, William , Leopold Center for Sustainable Agriculture

With Iowa farmers returning land from the Conservation Reserve Program and pasture use to crop production, there is a need to deal with potential wireworm infestations. Researchers sought to develop an early warning system for locations "at risk" from wireworms, using Geographical Information Systems technology. User-friendly wireworm diagnostics for farmers were researched, along with low-risk cropping alternatives to planting insecticide-protected corn. Integrated Pest Management (IPM) recommendations were generated that, if implemented, will reduce unnecessary insecticide use in Iowa.
