Steward (Dpx MP-062), a Novel New Insecticide for Cotton Insect Control

Glenn G. Hammes, Dan Sherrod and Dave Marsden


"Steward," under the DuPont test codes JW062 and MP062 has been extensively evaluated to determine use rates and application timing required to control economic pests while minimizing impact on beneficial arthropods. "Steward" represents a novel new mode of action which is primarily exhibited via ingestion of the insecticidally active isomer KN128 (indoxacarb.) In field studies throughout the cotton belt, "Steward" has demonstrated a high degree of activity on the Heliothine complex, fall armyworm, beet armyworm, cabbage looper, soybean looper, and the tarnished plant bug. Field and laboratory studies on the major beneficial arthropods found in U.S. cotton indicate "Steward" as soft on the major beneficials which will facilitate its use and utility in cotton pest management programs.
