Abstract
Dose-response data for a salicylanilide insecticide (4',5-dichloro-3-(4-chlorophenyl) salicylanilide) and for toxaphene-DDT (2:1) were determined against larvae of bollworm, Heliothis zea (Boddie), caged individually on leaves of young, previously sprayed, cotton plants. Comparison of the calculated LD50and LD90rates shows that the newer compound is 5-7 times as effective as the standard at the LD50, and that it has a steeper dose-response curve. Like the standard, deposits of the salicylanilide are active for several days after treatment. A very low order of toxicity to mammals is indicated by results obtained with laboratory animals.This publication has 1 reference indexed in Scilit:
