SYNOPSIS

With the incoming heatwave, we expect to have corn tassels by the 4th of July. With rain almost every week, it is no surprise that gray leaf spot has started to show up, and a few lesions can be found on the second leaf from the ground. Early planted soybeans are full of blooms and at R2. Septoria brown spot is just starting to show up on lower leaves. Fungicide applications will need to be made soon on both corn and soybeans. Interesting to note that I have not been able to spot many Japanese beetles yet. Meanwhile, rain has hindered post herbicide applications on late planted soybeans. It has also put a damper on the wheat harvest and planting double-crop soybeans.
