| Use | has the advantages of gastric poison, contact killing and internal absorption, high efficiency, low toxicity and safety. It has special effects on aphids, and can be used to control aphids in wheat and peach trees. To control wheat aphids, at the booting stage of wheat, when the rate of stem reached 30% and the population was above 150, 25% emulsifiable concentrate 1250~1500mL/hm2 (effective component 312.5 ~ 375g) was used. The water 750 ~ 900kg spray, the sustained effect period is 5 ~ 7d, the two medication interval 10d. Control of Myzus persicae with 25% emulsifiable concentrate 500~1000 times liquid spray. methyl ethyl dithiocarbamate is a kind of high efficiency, low toxicity and low residue of systemic carbamate insecticide, which has good control effect on aphids, crustaceans, diamondback moth, cockroaches, mosquitoes and flies, for the control of fruit trees, vegetables, potatoes, sugar beet, tobacco and other crops on the aphids, aphids resistant to organic phosphorus is more effective, with a long residual effect. |
| production method | using phenol as raw material, synthesis of intermediate O-ethylthiomethylphenol by one-step pressure method, this is followed by addition with methyl isocyanate to produce ethyl thiomethyl. O-ethylthiomethyl phenol is prepared by the interaction of N-methyl isocyanate. |
