Weather-driven Grape IPM Forecast Models and Decision Aids from the Network for Environment and Weather Awareness

Abstract

Applications (NEWA) were improved further in 2010. The focus of the work was on the grape berry moth degree day model, on making improvements to the displays and pest management messages for the grape diseases powdery mildew, black rot and Phomopsis cane and leaf spot and on migrating the DMCast model into the Northeast Regional Climate Center database and NEWA server. We also completed the leaf wetness algorithm investigations, presented talks on NEWA, supported Extension educators' contributions to newsletters to multiply the use of NEWA information for IPM, and grappled with the complete loss of NYS IPM Program funding support for NEWA due to the New York State budget crisis.
