Nontoxic Mode of Action Against the Target Pest

Nontoxic Mode of Action Against the Target Pest 

The USEPA considers the term nontoxic, with respect to the mode of action, to imply that no chemical or biological interaction of the biopesticide molecule occurs with the physiology of the target pest organism such that direct lethality results to that pest organism. Lethal effects, when they occur, are always downstream from the initial exposure to the biochemical pesticide and are typically the result of physicochemical processes, 

Although not limited to these uses, the following modes of action are considered to be nontoxic for classification of a substance as a biochemical pesticide  

Insect growth regulation, suffocation, and desiccation as modes of action have been discussed above. The following briefly discusses the other nontoxic modes of action typical of biochemical pesticides.
