Application:
USE ALONE: Deltamethrin is effective against most plant pests except cotton mites and cotton boll weevils. It may be applied to food and field crops, market gardens, orchards and vineyards by air or ground spray equipment, at rates of up to 11g/ha or as recommended by the manufacturer. It may also be sprayed on greenhouse plants, on buildings and other inert surfaces, and on animals. Special formulations for oral or
Dipping applications have also proved effective against cattle ectoparasites.
PUBLIC HEALTH USE - Deltamethrin has had some experimental use against disease vector insects with limited success. Its repellent action may limit its effectiveness in some eradication programmes.
HOUSEHOLD USE - Deltamethrin is primarily an agricultural insecticide and has no recommended household use.
Mode of action: The parent compound is the active toxin; Deltamethrin is a neurotoxin acting primarily on the basal ganglia of the central nervous system. It causes repetitive nerve action through prolongation of sodium
Permeability during the recovery phase of the action potential in neurons.Unit Price/Payment:T/T in advanceOrigin:ChinaSynonyms : Deltamethrin;(S)-α-Cyano-m-phenoxybenzyl-(1R,3R)-3-(2,2-dibromoyinyl)-2-dimethyl cyclopropane carboxylate;(S)α-cyano-3-phenoxybenzyl(1R)-cis-3-(2,2-dibromovinyl) -2,2-methylcyclopropanecarboxylate;Delatmethrin; 98% Deltamethrin TC;Thiocyclam Hydrogen Oxalate;(S)-a-cyano-3-phenoxybenzyl-(1R)-cis-2,2-dimethyl-3-(2,2-dibromovinyl)cyclopropanecarboxylate;(S)-a-cyano-3-phenoxybenzyl (1R,3R)-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylate;(S)-a-cyano-3-phenoxybenzyl (1R)-cis-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylate;[1R-[1a(S*),3a]]-cyano(3-phenoxyphenyl)methyl 3-(2,2-dibromoethenyl)-2,2-dimethylcyclopropanecarboxylate;(S)-cyano(3-phenoxyphenyl)methyl (1R,3R)-3-(2,2-dibromoethenyl)-2,2-dimethylcyclopropanecarboxylate;cyano(3-phenoxyphenyl)methyl (1R,3S)-3-(2,2-dibromoethenyl)-2,2-dimethylcyclopropanecarboxylate;(1r-(1-alpha(s*),3-alpha))-oxyphenyl)methyleste;deltametrin; Molecular Structure :
