Profenofos non-systemic organophosphorus pesticide
What is Profenofos Cas 41198-08-7?Profenofos is an insecticide used on a wide variety of crops to control many pests but mainly Lepidoptera and mites. Cas 41198-08-7It is non-systemic with contact and stomach action, and an acetylcholinesterase (AChE) inhibitor. It is a broad-spectrum organophosphorous pesticide that is used widely in cotton fields for insect control. It is a pale yellow liquid with garlic-like odor and corrosive. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Profenofos is an organophosphate insecticide. It is a liquid with a pale yellow to amber color and a garlic-like odor.
Profenofos is an organic thiophosphate, an organophosphate insecticide, an organochlorine insecticide and a member of monochlorobenzenes. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor, an acaricide and an agrochemical. It is functionally related to a 4-bromo-2-chlorophenol.
Profenofos Mode of Action Cas 41198-08-7
Profenofos is a neurotoxin acting as a cholonesterase inhibitor in insect nervous system. The separate optical isomer, due to the chiral phosphorus atom, shops different types of insecticidal activity and ability to inhibit acetyl cholinesterase.
Profenofos Mechanism of action Cas 41198-08-7
Like other organophosphates, the profenofos mechanism of action is via the inhibition of the acetylcholinesterase enzyme. Although it is used in the form of a racemate, the S(-) isomer is a more potent inhibitor.
Profenofos Uses Cas 41198-08-7
An insecticide/miticide, profenofos is a restricted use pesticide used solely on cotton, to control the tobacco budworm, cotton bollworm, armyworm, cotton aphid, whiteflies, spider mites, plant bugs, and fleahoppers. An estimated 85% of all profenofos is used to control
lepidopteran species (the worm complex) at varying rates. About 30% of this use is at the maximum label rate of one pound active ingredient per acre.
Approximately 775,000 pounds of active ingredient are applied to cotton crops each year.
Profenofos can be used on a variety of crops including cotton and vegetables such as maize, potato, soybean, and sugar beet. it is used exclusively on cotton and is primarily used against lepidopteran insects.
Mixed with phoxim, cypermethrin, beta-cypermethrin imidacloprid and deltamethrin, profenofos can be used against Cotton MealyBug, cabbage caterpillar, Plutella xylostella and asparagus caterpillars, as well as against wheat and cabbage aphids.
Profenofos Toxicity Cas 41198-08-7
Based on a study of patients poisoned with profenofos and its close chemical relative prothiofos, the compound has been described as "of moderately severe toxicity", causing respiratory failure. Differences in chemical structure that distinguish these two compounds from more common organophosphate pesticides - namely, the presence of the S-alkyl group on the phosphorus atom where most OP compounds possess a methoxy or ethoxy group - underlie differences in their behavior as acetylcholinesterase enzyme inhibitors compared.
profenofos poisoning, the major metabolites of profenofos were identified as des-S-propylated profenofos, two isomers of despropylated propenofos, and desethylated propenofos.A downstream, nontoxic metabolite, 4-bromo-2-chlorophenol, has been proposed as biomarker for exposure.

Profenofos Precautions Cas 41198-08-7
Reduce the maximum application rate to 0.75 pounds of active ingredient per acre
Allow the higher rate (1 pound active ingredient per acre) only on lepidopteran pests up to twice per season
Require closed mixing/loading systems and enclosed cockpits and cabs
Prohibit pilots from mixing and loading on the same day as application
Reduce the seasonal application rate from 6 to 5 pounds active ingredient per acre per season.
Require a notice on the label to inform certified crop advisors of the need to provide the proper level of protective clothing and equipment for workers reentering treated fields.
To mitigate ecological risks
Require a 300 foot buffer zone around bodies of water for aerial applications
Require a 100 foot buffer zone around bodies of water for groundboom applications.
The reduced application rates discussed above should also reduce ecological risks.
