General Information


Use low rate under light to moderate infestation. Higher rates should be used under heavy insect pressure. The rate of application is variable according to insect pressure, timing of spray and field scouting.

In New York State this product may not be applied within 100 feet (using ground equipment) to 300 feet (using aerial equipment) of coastal marshes or streams that drain into coastal marshes.

Preventive Use

For cutworm, armyworm grape colaspsis, or stalk borer control, STEED Insecticide may be applied before, during, or after planting. For soil-incorporated applications, use higher rates for improved control.

Limitations, Restrictions, and Exceptions




- PHI: Do not apply within 30 days of harvest for grain and stover and 60 days of harvest for forage.

- Application Interval: Apply at a minimum 3 day intervals or as needed for control.

- Refer to the maximum usage tables when applying more than one product containing either zeta-cypermethrin or bifenthrin to this crop.

- Grazing: Do not graze livestock in treated areas or cut treated crops for feed within 30 days of the last application.

Use of ultra low volume (ULV) application on corn is prohibited.

Apply in a minimum of 2-5 gallons of finished spray per acre by air or in a minimum of 10 gallons per acre with ground equipment. To improve control by aircraft, use 5 gallons of finished spray per acre, particularly when initial populations are heavier than normal. When applying by air, 1– 2 quarts of emulsified oil may be substituted for 1– 2 quarts of water in the finished spray.

Thorough coverage is essential to achieve control.

To control ear– attacking pests: Apply STEED Insecticide when silking begins and repeat as necessary to maintain control.

Southwestern Corn Borer, European Corn Borer: Make 2 applications for corn borer control with the first application at or shortly before egg hatch followed by the second application 7 – 10 days later.

For control of other insect pests: Apply when pests first appear and repeat as necessary.

Higher rates will be necessary for heavier initial populations and corn under heat or drought stress.

Armyworm Fall; Corn Earworm: Coverage is essential for control of this pest. Under heavy outbreaks tank mixing with another product that is labeled for this pest is recommended for control.

Tobacco Budworm: Pyrethroid resistance is common for these pests. Please consult your local or state agricultural authority to determine if resistance pest populations are in your area. If so refer the resistance management statement in the DIRECTION FOR USE section of the label.
