What is malathion what is its mechanism of action?
Mechanism of action Malathion is an acetylcholinesterase inhibitor, a diverse family of chemicals. Upon uptake into the target organism, it binds irreversibly to the serine residue in the active catalytic site of the cholinesterase enzyme.
What is chlordane pesticide?
Chlordane, or chlordan, is an organochlorine compound that was used as a pesticide. It is a white solid. In the United States, chlordane was used for termite-treatment of approximately 30 million homes until it was banned in 1988.
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?
OSHA: The legal airborne permissible exposure limit (PEL) is 0.5 mg/m3 averaged over an 8-hour workshift.
What are pesticides used for?
Pesticides are used to control various pests and disease carriers, such as mosquitoes, ticks, rats and mice. Pesticides are used in agriculture to control weeds, insect infestation and diseases. There are many different types of pesticides; each is meant to be effective against specific pests.
What is the pH of chlorpyrifos?

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.
