What are organophosphates and carbamate pesticides?

What are organophosphates and carbamate pesticides?

Organophosphates and carbamates are common insecticide ingredients that inhibit cholinesterase activity, causing acute muscarinic manifestations (eg, salivation, lacrimation, urination, diarrhea, emesis, bronchorrhea, bronchospasm, bradycardia, miosis) and some nicotinic symptoms, including muscle fasciculations and …

What are carbamates pesticides?

Carbamates are used as sprays or baits to kill insects by affecting their brains and nervous systems. They are used on crops and in the home to kill cockroaches, ants, fleas, crickets, aphids, scale, whitefly, lace bugs and mealy bugs. Some carbamates control mosquitoes.

Are pyrethroids organochlorines?

Most other organochlorines (except chlordecone), as well as certain (type II) pyrethroids, block the chloride channels of the GABA-A receptor, and cause seizures.

What are organophosphate pesticides?

Organophosphate insecticides (such as diazinon) are one type of pesticide that works by damaging an enzyme in the body called acetylcholinesterase. This enzyme is critical for controlling nerve signals in the body. The damage to this enzyme kills pests and may cause unwanted side effects in exposed humans.

What is the difference between organophosphates and carbamates?

The key difference between carbamates and organophosphates is that carbamates do not contain phosphate, whereas organophosphates essentially contain phosphate. We can find the terms carbamates and organophosphates in the field of agriculture under the subcategory of insecticides. Both of these are organic compounds.

What is an organophosphate pesticide?

Is pyrethroid an organophosphate?

Pyrethrins are natural botanical insecticides derived from extracts of the flowers of Chrysanthemum genus, primarily Chrysanthemum cinerariaefolium and coccineum,1 while pyrethroids are synthetic derivatives of pyrethrins. In contrast to organophosphate insecticide, pyrethroids are less toxic to human.

What is an example of organophosphate?

Organophosphate (OP) compounds are a diverse group of chemicals used in both domestic and industrial settings. Examples of organophosphates include the following: Insecticides – Malathion, parathion, diazinon, fenthion, dichlorvos, chlorpyrifos, ethion. Nerve gases – Soman, sarin, tabun, VX.
