The Bacillus thuringiensis subsp. aizawai insectide XenTari* DF and the synthetic pyrethroid active ingredient bifenthrin were tank mixed and applied to cabbage for control of diamondback moth (Plutella xylostella) larvae. The tank mix combination of low label rates of XenTari* with bifenthrin provided better control than higher rates of either insecticide alone. Low to moderate rates of synthetic pyrethroids and Bt can provide good control with potential additional benefits such as beneficial insect conservation and reduced MRL concerns.
