SYNOPSIS

Both corn and soybean crops look great right now, with plentiful moisture from rains throughout most of July. This is keeping the crop green and mostly healthy, with the exception of corn leaf diseases coming in and an array of soybean feeders as well. I believe that growers who decided to spray fungicides this season will be happy with that choice. I worry about fields that were not sprayed. Unfortunately, I also see enough disease coming back in now that a second application may become necessary due to increasing tar spot and other diseases. Our saving grace will be that the corn crop is maturing at a rapid pace.
