Volume 54 Number 10 June 26 2009This Week's Weather & Pests High temperatures and humidity pushed heat index values to 95-100 across much of Wisconsin during the week, prompting the National Weather Service to issue a heat advisory for Tuesday and Wednesday. Localized rain in southern and eastern counties benefitted field crops, while drought remains a concern for farmers in the northwest growing areas. The hot, humid weather was especially timely for soybeans and corn, most of which are rapidly advancing through the vegetative phases. Corn in particular has shown remarkable growth and many fields are presently at the V8-V9 stages. Soybean emergence is 90% complete, with the status of the crop reported as fair to excellent. Conditions have been ideal for the development of many pest insects, the most noteworthy being the European corn borer and potato leafhopper. |
