Thus, ground applications of sprays are usually much more effective than aerially applied sprays. European and Southwestern Corn Borers - Detailed information on European and southwestern corn borers can be found on the corn borer insect management web page. Chinch Bugs - Chinch bugs occasionally attack corn and may cause severe stunting and yield reductions. Chinch bugs are routinely a problem in certain areas of the state and intensive management may be required to control this insect. Young immature nymphs have red bodies with a white stripe across the back.
Older nymphs are darker, lacking the stripe and reddish abdomen.
Chinch bugs are normally found near or below the soil line and behind leaf sheaths. A soil-applied granular insecticide such as Furadan will give control for approximately 30 days after emergence. Foliar treatments should be directed toward the base of the plants in 25 to 30 gallons solution per acre. Grasshoppers - Grasshoppers may occasionally be a problem in field border rows. The control of grasshoppers is usually necessary only in localized areas of the field and spot treatments are usually the best way to apply controls.
