Monday, November 20, 2017. 11:00AM. Webinar: Insect Pests and Pathogens in Dryland Cereal Systems. Tim Paulitz, USDA-ARS Pullman Washington. Sponsored by Regional Approaches to Climate Change- Pacific Northwest Agriculture and the Climate Learning Network. More information here.
This will be a two-part webinar with overviews on some of the key insect pests and pathogens affecting our cereal systems in the dry inland Pacific Northwest. Insects to be covered are cereal aphids, cereal leaf beetle, Hessian fly, and wireworms. The webinar will cover highlights of the biology of each, considerations for their management, and how projected climate change might affect them. Video segments help with recognition of some of these species. It will also cover five important soil borne diseases of wheat and rotation crops. The first four are caused by fungi and the last one by nematodes, microscope worm-like animals. All of these pathogens reproduce and grow in the soil and attack the seeds, seedlings, roots, and lower stems of wheat. These are Pythium seed and root rot, Rhizoctonia bare patch and root rot, strawbreaker foot rot (eyespot), Fusarium crown rot and cereal cyst nematode. Soil borne diseases are difficult to diagnose because the aboveground symptoms may resemble other abiotic causes such as nutrient deficiency or drought. The video will look at the diseases in the field, and will examine below-ground symptoms on roots and at the base of the stems (crowns). This section will also cover management strategies for these diseases.
