Product Description
Decamethrin is a synthetic compound that modulates sodium channels in the nerve cell membrane.This compound can keep the Na+ channels in an open state for a long time resulting to hyperactivity of the nervous system in mammals and insects.Deltamethrin can increase neurotransmitter release which is associated with elevated levels of intrasynaptosomal free Ca2+ and protein phosphorylation activities.Research shows that in the presence of increasing concentrations of deltamethrin,and GH-I significantly decreased in rainbow trout.Deltamethrin is an inhibitor of PP2.

Mode of action
Non-systemic insecticide with contact and stomach action.Fast-acting.
Function
A potent insecticide, effective by contact and ingestion against a wide
Range of pests.Crop protection uses include:Coleoptera (2.5-7.5 g/ha),
Heteroptera (5.0-7.5 g/ha), Homoptera (6.2-12.5 g/ha), Lepidoptera
(5.0-21 g/ha) and Thysanoptera (5-10 g/ha) in cereals, citrus, cotton, grapes,
Maize, oilseed rape, soya beans, top fruit and vegetables.It controls Acrididae
(5.0-12.5 g/ha), and is recommended against locusts.Soil surface sprays
(2.5-5.0 g/ha) control Noctuidae.It is used against indoor crawling and flying
Insects (12.5 mg/m2) and pests of stored grain (0.25-0.5 g/t) and timber
(Blattodea, Culicidae, Muscidae).Dip or spray (12.5-75 mg/l), and pour-on (0.75 mg/kg b.W.) applications give good control of Muscidae, Tabanidae,
Ixodidae and other Acari on cattle, sheep and pigs, etc.
