ALWAYS CONSULT THE INSECTICIDE LABEL BEFORE MAKING INSECTICIDE DECISIONS
*Insecticide Group: M=microbials, C=carbamates, OP=organophosphates
**LD 50 values represent the relative toxicity of a pesticide. They represent the dose
(in mg/kg body weight) that will kill 50% of the test animals. Thus the lower the
number the greater the toxicity. Values given are for oral LD 50.
