In 40 CFR 156.62, the EPA established four Toxicity Categories for acute hazards of pesticide products, with "Category I" being the highest toxicity category (toxicity class). Most human hazard, precautionary statements, and human personal protective equipment statements are based upon the Toxicity Category of the pesticide product as sold or ...
1,2-Dibromo-3-chloropropane (dibromochloropropane), better known as DBCP, is the organic compound with the formula BrCH(CH 2 Br)(CH 2 Cl). It is a dense colorless liquid although commercial samples often appear amber or even brown. It is the active ingredient in the nematicide Nemagon, also known as Fumazone.
A few additional screening questions about the patient's work and home environment, in addition to a typical health questionnaire, can indicate whether there was a potential pesticide poisoning. [24] If one is regularly using carbamate and organophosphate pesticides, it is important to obtain a baseline cholinesterase test.

Pyrethrin I (C n H 28 O 3) and pyrethrin II (C n H 28 O 5) are structurally related esters with a cyclopropane core. Pyrethrin I is a derivative of (+)- trans - chrysanthemic acid . [ 12 ] [ 13 ] Pyrethrin II is closely related, but one methyl group is oxidized to a carboxymethyl group, the resulting core being called pyrethric acid.
Cyfluthrin is a pyrethroid insecticide and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of isomers.Like most pyrethroids (MoA 3a), [1] it is highly toxic to fish and invertebrates, but it is far less toxic to humans. [2]
Piperonyl butoxide (PBO) is a pale yellow to light brown liquid [1] organic compound used as an adjuvant component of pesticide formulations for synergy.That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.

[3] Pesticide resistance is increasing. Farmers in the US lost 7% of their crops to pests in the 1940s; over the 1980s and 1990s, the loss was 13%, even though more pesticides were being used. [1] Over 500 species of pests have evolved a resistance to a pesticide. [4] Other sources estimate the number to be around 1,000 species since 1945. [5]
