Light Horticultural Oil - Light horticultural oil, having a viscosity of 60 to 70 controls corn earworm during the growing season. Spray a 2 to 3% solution of oil in water directly on the earworm. The oil works by suffocation. If you add Bt to this light oil spray you increase its effectiveness significantly (see above).
Pyrethrum - Pyrethrum, a botanical poison, paralyzes corn earworm on contact. So spray the undersides of the leaves as well as the tops, since the worm is usually on the underside and must be sprayed directly. Usually two applications, three to four days apart will control the problem.
Rotenone - Rotenone is both a stomach and a contact poison to corn earworm. Dust it or dilute it with water for spraying. A 5% concentration in water will kill earworms. It can be used up to 24 hours before harvest. However, while it is effective against many pests, rotenone also kills beneficial insects.
