Is Chlorfenapyr an organophosphate?

Chlorfenapyr is a pyrrole-based pro-insecticide. The main activity of this agent is the inhibition of adenosine triphosphate synthesis, and it is used in agriculture to control several insects and mites resistant to carbamate, organophosphate and pyrethroid insecticide.

What is the purpose of chlordane?

First produced commercially in 1947, chlordane has been used primarily for termite eradication around housing foundations and for control of soil insects in corn production. Chlordane also has been an active ingredient in many household and garden pesticides (Infante et al., 1978).

What is the regulatory limit for chlordane?

Is chlorfenapyr systemic?

Moreover, the final residues of chlorfenapyr on plants were below the maximum residue limits (MRLs) as a result of its non-systemic activity. These results demonstrate that chlorfenapyr has potential as a potent alternative to phoxim for controlling B.
