Isolates of Bacillus thuringiensis var. kurstaki in combination with a feeding stimulant (Coax®-a cottonseed flour adjuvant) were tested against the tobacco budworm (Heliothis virescens (Fabricius)) on flue-cured tobacco. Coax®, used as an adjuvant with B. thuringiensis, gave slight or no improvement in control of budworms established before treatment. In only one of three tests did it significantly enhance the control of budworm infestations established after application.
