More Aphid Ammunition | Soybeans with Genetic Aphid Protection Squelch No. 1 Soybean Pest

Two genes that help soybeans fend off aphids worked well in 2011, both as single and stacked traits. That’s according to a six-state study of soybeans with aphid resistance genes, known as Rag1 and Rag2. Individually, the genes slowed aphid growth significantly, says Iowa State University entomologist Matt O’Neal, who led the research.

    May 2012 Crop Update

    The corn and soybean crops are off to a nice start in southern Minnesota and northern Iowa, says Kent Thiesse, former Extension educator and vice president of MinnStar Bank in Lake Crystal, MN.

    Watch for Two-Spotted Spider Mite, Bean Leaf Beetles

    University of Illinois Professor of Entomology and Crop Sciences Extension Coordinator Mike Gray says that this year it is important to keep a watchful eye out for the two-spotted spider mite, especially as we head into some very hot and dry weather in the near term. “Because we are well ahead of schedule this spring regarding the occurrence of several pests, we should definitely scout for two-spotted spider mites, particularly if we continue to have hot and dry weather,” says Gray. “Let’s hope we don’t have issues with this pest in 2012.”...More

    Soybean Planting and Dry Soils

    University of Illinois Crop Sciences Professor Emerson Nafziger was recently asked whether it is a good idea to plant soybeans into dry soil. "It's a fairly common question, especially with soybeans, because they're more likely to be planted late, when soils are dry, and also because soybeans need to take on more water to germinate than corn seed does," he says. Soybean seed also does not draw water quite as strongly as corn seed does....More

Most of the seedling disease issues that are being reported are from fields that were planted April 23-27, just before we had a period of cold, wet conditions and soil temperatures dipped back down below 50° F....More

    May 10 USDA Reports Bring Mixed Results

    The USDA Crop Production and World Agricultural Supply and Demand Estimates (WADSE) reports released May 10 were regarded as bearish for the corn market and bullish for the soybean market in the coming months.

    3 Things to Watch After May USDA Reports: Corn Yield, Soybean Acreage, Corn Feed/Residual Use

    USDA reports frequently move markets and last week’s first supply/demand for the 2012 grain and oilseed crops was no exception.
