The Iowa State University Integrated Pest Management (IPM) Program is pleased to present the seventh annual Crop Scouting Competition for Iowa Youth. High school students (those completing grades 9-12) from Iowa are invited to compete and showcase crop scouting abilities in corn and soybean. The competition will be a one day event focusing on outdoor learning.
Japanese beetle is becoming a more common field crop pest in Iowa. Literature shows adults need about 1,030 growing degree days (base 50°F) to complete development. Japanese beetles will continue emergence until around 2,150 degree days. Based on accumulating degree day temperatures in 2014, Japanese beetle adults should be active in some areas of southeastern and southwestern Iowa this week (Fig. 1). Expect adults to emerge in central and northern Iowa in about 7-14 days if warm temperatures continue.
We will have a fair amount of corn tasseling shortly after the weekend – so fungicide application season is about here.
In talking with farmers and retailers the last week or so, based on all the rainfall and wet soils this is shaping up to be a big year for fungicide applications, so just a few thoughts for guys “on the fence” and trying to decide whether to spray or not.
