SDSU Extension Extra 5081: 2011 grasshopper rangelands outlook
April 1, 2011
BROOKINGS, SD – A new publication from the South Dakota Cooperative Extension Service gives a detailed forecast on grasshoppers in western South Dakota for 2011.
SDSU Extension Extra 5081, “Grasshopper Outlook on Rangelands: 2011” is available at: http://pubstorage.sdstate.edu/AgBio_Publications/articles/exex5081.pdf. Or ask for a copy of it at your county Extension office.
Extension Ranch Economist Martin Beutler and Extension Rangeland Specialist Roger Gates wrote the five-page publication with Bruce Helbig from the USDA’s APHIS Laboratory in Pierre.
Researchers conducted surveys on adult grasshopper in the fall of 2010, and those reports suggest a high probability for above-normal grasshopper populations during the 2011 growing season. The authors discuss alternative management and control strategies and provide financial guidance related to direct investment in application of insecticide for control.
