Fall armyworms and corn borers have long been a concern for Louisiana corn growers. While farmers in the U.S. have planted transgenic Bt corn varieties since the 1990s to biologically control pests, staying ahead of their ability to develop resistance is a constant battle.
As the corn in Ohio enters the tasseling and pollination stage, there are two insects that should be watched. However, both need to be scouted before tank mixing an insecticide with a fungicide spray gives a good return.
We don’t know what the insect pressure will be like later on yet this year. What we can do, however, is remind agronomists and crop consultants what we think are the most important insects for you to watch for in each of three key crops: corn, soybeans and wheat.
