Dimethoate

Common name: Dimethoate （CAS NO: 60-51-5）

IUPAC name:  O,O-dimethyl S-methylcarbamoylmethyl phosphorodithioate or
2-dimethoxyphosphinothioylthio-N-methylacetamide

Chemical Abstracts name: O,O-dimethyl S-[2-(methylamino)-2-oxoethyl] phosphorodithioate

Mode of action: 
Dimethoate can be rapidly oxidized into omethoate in plants and plants and in insects to increase toxic effects. It is an organophosphate insecticide and acaricide. It has strong knockdown ability to pests, and has strong systemic, contact and certain stomach toxicity.

Application:

1. Prevention and control of cotton pests: cotton aphid 50 ml per acre 40% emulsifiable concentrate, or 40 ml 50% emulsifiable concentrate, spray 60 kg of water. At the same time, this amount can be used to control cotton aphid and cotton leafhopper. Controlling mites and spider mites should focus on spraying the back of the leaves so that the liquids are more effectively in contact with the worms.
2. Prevention and control of rice pests: control of gray planthopper, whitebacked planthopper, brown planthopper, leafhopper and thrips, using 40 ml of 40% dimethoate per acre, or 50 ml of 50% emulsifiable concentrate, 75-100 kg of water spray.
3. Prevention and control of vegetable pests: control rapeseed, eggplant red spider, onion thrips, pea leaf miners, 50 ml of 50% emulsifiable concentrate per acre, spray 60--80 kg.
4. Control of tobacco pests: Control tobacco mites, smoked horses and tobacco nocturnal moths, using 60 ml of 40% dimethoate or 50 ml of 50% emulsifiable concentrate per acre and spraying 60 kg of water.
5. Control fruit tree pests: apple leafhopper, pear star caterpillar, hibiscus spray, 50% EC concentration 1000-2000 times. Red wax scale and other scale insects were sprayed with a 400-fold dilution of the 40% EC.
6. Prevention and control of tea tree pests: prevention and treatment of tea orange tarsonemid mite and tea green leafhopper, by spraying a 1000–2000-fold dilution of the 40% EC.
7. Control flower insects, hibiscus, fruit fly, blind cockroaches: spray 300-500 mg / kg concentration of liquid medicine.
8. Scaly worms, thorn moths, mites: Spray flowers 2000-3000 times with 40% emulsifiable concentrate.
