Corn and soybeans have survived a rough spring with challenging weather and pest concerns but yield prospects have been improving during the last two weeks as we approached silking. Observations made during this time can help to determine stand health and predict silage harvest dates.

Under certain conditions, applying a fungicide to corn may provide an economic return. A look at few key criteria will help in determining whether to apply fungicides or wait things out.

Corn Aphids have become a recent problem on some farms in Pennsylvania and are the result of imbalances of natural predators. Fortunately, through scouting and the use of economic thresholds this problem can be avoided.

We have plenty of reports this week from across the state that indicate low pest populations in the soybean fields we are scouting and the same conditions likely apply in most soybean fields around the state. For most of the issues we have seen, there appears to be little economic return in applying insecticides at this time.

As your canopies close and humidity levels rise, you can bet the fungi that cause crop diseases are getting happy. Scouting right now is going to be your best bet for making good fungicide decisions for your fields.

Most soybean fields appear to be growing well and are starting to experience some minor defoliation. Our reports from this week identify bean leaf beetles, Japanese beetles, and grasshoppers as the primary culprits. Remember that vegetative stages soybeans can tolerate up to 25% defoliation without dropping yield, so do not overreact if you find some feeding damage in your fields. For diseases, reports of Septoria brown spot and frogeye leaf spot appeared this week, but populations seem low.

Planting green is a practice where growers delay cover crop termination until cash crop planting. Instead of killing the cover crop 1-2 weeks ahead of cash crop planting, the cover is allowed to grow longer into the spring, which can extend soil conservation and health benefits provided by the cover crop.
