A statewide survey for viruses and soybean aphid prevalence was conducted from June 28th to August 10th, 2005. Observations and samples were collected from 276 R2-R5 soybean fields across Wisconsin. At four points in each field, the uppermost fully-unfurled trifoliate was picked from 10 plants and stored on ice until delivered to the Plant Industry Laboratory. Soybean aphid populations were counted, an estimation of defoliation percent made, and plants were examined for soybean rust.
