Evaluation of Bacillus Thuringiensis and Ovicide Combinations for Bollworm and Tobacco Budworm

C.D. Klein, D.R. Johnson, H.B. Myers, L.M. Page


Two tests were conducted to determine the efficacy of Bacillus thuringiensis/ovicide combinations against tobacco budworm and bollworm larvae. Bt + ovicides significantly reduced larval populations below the untreated check early season. No differences were observed later in the season. The combinations appear to have a greater reduction of larvae than Bt alone. Larvin in combination with Bt provided the best control of all ovicides tested.
