The mechanism of action:
Fenitrothion is an insecticide and acaricide with contact and digestive tract impact which has a severe traumatic effect and includes a moderate protective period (10 to 15 days). The ability of this poison to inhibit cholinesterase enzyme in the nervous system of animals. Acetylcholine acts as a neurotransmitter in the inter-synaptic space and stimulates the next axon. Fenitrothion causes accumulation in the synapse in the insect's body, and as a consequence, the subsequent stimulation of the lateral nerves continue, as the required cholinesterase enzyme for acetylcholine decomposition in the inter-synaptic space and the removal of this continuous stimulation are blocked by fenitrothion.
usage items :
Fenitrothion is used to control weevils, thrips, locust, larvae of butterflies and cockroaches, flies and sucking insects such as aphids, psyllas, scale insects and bugs on wheat, barley, rice, vegetables, fruit trees, vine, pistachio, sugarcane, alfalfa, Tobacco, cotton, citrus, pastures, forests, and so on.
Compatibility and Mixing:
Fenitrothion in concentrations higher than the recommended level on some vegetables such as cabbage creates allergy and causes some blight on some apple varieties. This compound is rapidly hydrolyzed in alkaline medium whereas it is slowly hydrolyzed in acidic media. It is mixed with all common fungicides and insecticides, but it is incompatible with alkaline compounds such as Bordeaux mixture. The active ingredient of this compound has a corrosive effect on iron.
