use | used as vegetable fungicide protective fungicide, which has a certain systemic therapeutic effect. It is mainly used to control rice sheath blight, rape sclerotinia and tobacco scab. For example, the prevention and control of Sclerotinia sclerotiorum of rape is 4.5~7.5g/100 m2 once and 6~15g/100 m2 twice according to the effective ingredients, and the control effect is 90% ~ 100%. Sclerotinia sclerotiorum is an agricultural fungicide, which has a good control effect on rice sheath blight, rape Sclerotinia sclerotiorum, tobacco red star disease, etc. The prevention and control of Sclerotinia sclerotiorum of rape is 30-50g per mu once and 40-100g per mu twice according to the effective components, with the prevention and control effect reaching 90-100%. The oral LD50 of this product is 1280mg/kg for male mice and 2073mg/kg for male mice. |
Production method | is obtained by the reaction of 3, 5-dichloroaniline and succinic acid. It is prepared by the reaction of 3, 5-dichloroaniline and succinadiamine. 243kg 3,5-dioxyaniline, 186kg of succinic acid and 2.5kg of sulfuric acid are added into the reaction kettle, and heated to 170 ℃ until all the water generated by the reaction is steamed out. After the reaction is over, the material is discharging while hot and cooled to obtain sclerotium clean powder with 87.4% yield. It can also be prepared by the following methods: |
