Acute toxicity of chlorantraniliprole to non‐target crayfish (<i>Procambarus clarkii</i>) associated with rice–crayfish cropping systems

Abstract

Chlorantraniliprole is three orders of magnitude less acutely toxic to P. clarkii than lambda-cyhalothrin and etofenprox, two pyrethroid insecticides also used in rice, and is less likely to cause acute crayfish toxicity in rice pond ecosystems. Based on acute toxicity data, the use of chlorantraniliprole should be more compatible with rice-crayfish crop rotations than pyrethroids.
