Soybean Research Verification Program Update – August 3, 2012
Author: Chris Grimes, Program Associate - Soybean/Wheat Verification Coordinator

Irrigation continues to be the main focus in the program. The recent rainfall and cloudy conditions in parts of the state has sparked some disease development in some of the fields, thus requiring fungicide applications. Insect pressure has picked up in some areas this week resulting in some treatments being recommended. A few fields have reached R6 growth stage and we are approaching irrigation termination on those fields.
