This Week’s Weather & Pests
Early July heat and humidity accelerated crop development throughout Wisconsin. Temperatures were well above average and reached or exceeded the 90-degree mark for several consecutive days, as mainly dry weather with localized showers and storms prevailed during the week. From June 27-July 8, Madison recorded 12 days in a row of highs above 85°F, the hottest stretch of weather since 2012.
Meanwhile, harvest of second crop alfalfa continued across the state, with growers reporting 75% of the crop in good to excellent condition. Ratings for both corn and soybeans were similar at 79% in the good to excellent categories, far above 59% and 64%, respect- ively, at this time last year. Pressure from mid-season insect pests such as potato leafhoppers and Japanese beetles intensified in response to the hot weather, and surveys indicate above-threshold populations are developing in various crops.
