Organophosphate poisoning is poisoning due to organophosphates (OPs). [4] Organophosphates are used as insecticides , medications, and nerve agents . [ 4 ] Symptoms include increased saliva and tear production, diarrhea , vomiting, small pupils , sweating, muscle tremors, and confusion. [ 2 ]
Cypermethrin is a broad-spectrum insecticide, which means it kills beneficial insects as well as the targeted insects. [14] Fish are particularly susceptible to cypermethrin, [ 15 ] [ 16 ] but when used as directed, application around residential sites poses little risk to aquatic life. [ 17 ]
Naled (Dibrom) is an organophosphate insecticide. [3] [4] Its chemical name is dimethyl 1,2-dibromo-2,2-dichloroethylphosphate. Naled is stable in anhydrous condition and must be stored away from light. It must also be stored under normal pressure and temperatures.
Sulfotep (also known as tetraethyldithiopyrophosphate and TEDP [8]) is a pesticide commonly used in greenhouses as a fumigant. The substance is also known as Dithione, Dithiophos, and many other names. Sulfotep has the molecular formula C 8 H 20 O 5 P 2 S 2 and belongs to the organophosphate class of chemicals.
This results in abnormal accumulation of ACh within the nervous system. Diazinon, although a thiophosphoric ester, shares a common mechanism of toxicity with other organophosphate insecticides such as chlorpyrifos, malathion and parathion, and is not very effective against the organophosphate-resistant insect populations.

It is very toxic both for target organisms and for mammals including humans. It inhibits acetylcholinesterase and butyrylcholinesterase. [3] Phorate is most commonly applied in granular form. It is non-biocumulative and has no residual action. But some metabolites may persist in soil. It also damages some seeds. [3]
Dimethoate is a widely used organophosphate insecticide and acaricide. It was patented and introduced in the 1950s by American Cyanamid. Like other organophosphates, dimethoate is an acetylcholinesterase inhibitor which disables cholinesterase, an enzyme essential for central nervous system function. It acts both by contact and through ingestion.
In November 2006, BASF sold its global Terbufos insecticide business to American AMVAC (American Vanguard Corporation). [14] Organophosphate poisoning is not common in the developed world. Most cases of terbufos poisoning occur in the developing world, where protection against pesticides is scarce, but compounds such as terbufos are widespread ...
