Weekly Crop and Weather Report

August 4, 2009

The Aug. 3 crop and weather report includes Iowa State University Extension climatologist Elwynn Taylor, integrated pest management specialist Rich Pope, and corn agronomist Roger Elmore visiting with ISU Extension communication specialist Doug Cooper.

Taylor says July was officially the second coldest month on record (1891 was the coldest by one tenth of a degree). The forecast for August is mixed, rain in the east and dry in the central and western areas. Taylor discusses the major hail storm that hit northeastern Iowa on July 24 and the related images available at http://mesonet.agron.iastate.edu/

Soybean aphids are reaching threshold in some areas, according to Pope; he recommends scouting for the pest. The key from now until harvest is to avoid stressing crops.

Corn agronomist Elmore says the cool or cold July can have a negative impact on yields. He says a late frost would be very helpful in getting the crop to reach maximum yield potential.
