| uses | carbamate systemic insecticides, cholinesterase inhibitors. The molecular structure contains triazole groups, which is a broad-spectrum, efficient and highly selective aphid killing agent, and has good control effect against resistant aphids. Because the agent can form upper and lower biphasic conduction in crop vessels, soil medicine can prevent and control leaf-eating aphids, and foliar spraying can prevent and control root-eating aphids, thereby protecting the entire plant. The recommended dosage is 0.6~0.9g active ingredient/100 m2, 0.9~1.5/100 m2 is required to control resistant aphids and cotton aphids, and 1.8~2.3g/100 m2 is required to control aphids. The efficacy period of the drug is as long as 10~15 days. |
| Production method | Preparation of 3-tert-butyl -5-mercapto-1, 2,4-triazole 2, 2-dimethylpropionyl chloride reacts with thiourea to form acylated thiourea, and then treated with sodium hydroxide aqueous solution to form 3-tert-butyl -5-mercapto-1, 2,4-triazole. Synthesis of Zolebub 3-tert-butyl -5-mercapto-1, 2, 4-triazole reacts with ethyl chloroacetate, and then reacts with dimethylcarbamoyl chloride to synthesize Zolebub. |
