Lower insect populations have led to minor crop damage this summer, but a Purdue Extension entomologist says farmers should still watch for anomalies when scouting.
Part of what has caused fewer insects has been the weather. Temperatures have been mild, and rainfall has been timely for most of the growing season. Most importantly, the crops had good conditions for growth during the critical period just after planting.
“We’ve had a good summer for growing conditions,” Christian Krupke said. “We’ve had rain, and plants just aren’t as vulnerable.”
Some insect pests that still have caused some damage to crops this summer are bean leaf beetles in soybeans and armyworms in corn.
Krupke has received reports of bean leaf beetle populations from all over the state, but the damage is more severe in northern counties. Some reports have described minor pod scarring, which isn’t of much concern. Other reports, however, have included pods clipped from stems.… Continue readingRead More »
