Mid-South Insecticide Resistance Management Guidelines for 1993

B.R. Leonard, R.G. Luttrell, and J.B. Graves


 
ABSTRACT

Numerous instances of unsatisfactory control of tobacco budworm, Heliothis virescens (F.), in the Mid-South states of Arkansas, Louisiana and Mississippi were reported in 1992. Most problems were related to economically damaging populations that persisted over an unusually long time period. Laboratory tests by University and USDA-ARS entomologists confirmed substantial levels of resistance to recommended insecticides including carbamates, organochlorines, organophosphates and pyrethroids in samples of tobacco budworm collected from these areas. In response to this problem, as well as the fact that no new classes of insecticides will be available in 1993, federal and state entomologists developed a series of guidelines to assist cotton producers in managing insecticide resistant tobacco budworm. These guidelines promote agronomic and integrated pest management practices for production of an early maturing cotton crop to reduce the probability for severe yield losses caused by tobacco budworm. A specific insecticide use strategy is recommended to spread the risk of tobacco budworm control failures among all available classes of insecticides.
