Wheat Stem Sawfly
We are seeing high wheat stem sawfly pressure in our field sites at New Raymer. Here are some pictures of sawfly attack in New Raymer. Dr. Mason and Sally Diamond-Jones also report high pressure in Akron. Ron Meyer said that crop scouts are reporting heavy sawfly pressure in the Yuma County – Kit Carson County border north of Stratton and near Vernon. Some fields have 20 WSS per foot of row!
