SYNOPSIS

It was a hot one and the early planted/earlier maturity corn and soybeans are starting to turn quickly. Corn is 1/2 to 3/4 milk line depending on maturity. Thus, far grainfill seems to be just fine, but would really like some rain to finish out the season. Many have started to watch out for stalk rot to know which corn fields to harvest first. Cercospora leaf blight started to show up in soybeans.
