Title: Suppression of Heliothis spp. on Cotton by using Bacillus thuringiensis, Baculovirus heliothis, and Two Feeding Adjuvants123
Abstract: The application of Bacillus thuringiensis Berliner and Baculovirus heliothis to cotton suppressed Heliothis spp. populations an average of 28% compared with the untreated check during field tests in 1980. The addition of the feeding adjuvants Coax® and Gustol® to the microbial insecticides increased the control by reducing the number of larvae by 46% in 1979 and 54% in 1980. The two feeding adjuvants Gustol® and Coax® improved efficacy of the microbial insecticides, but neither proved better than the other. In addition, spray combinations of B. heliothis + B. thuringiensis + feeding adjuvants did not prove to be superior to either pathogen alone + feeding adjuvants. For full-season use, the Heliothis spp. control in cotton using the microbials plus feeding adjuvants was not adequate compared with the insecticide standard permethrin. Significantly higher yields and lower Heliothis spp. populations were found With permethrin.
