use | systemic fungicide has both protective and therapeutic effects, and the use effect is obvious under low temperature and high humidity conditions. Used for rape, radish, eggplant, cucumber, cabbage, tomato, sunflower, watermelon, strawberry, onion, peach, cherry, flower, grape and other crops to prevent gray mold and sclerotinia and gray star disease, flower rot, Brown rot, vine blight, etc., can also be used to resist thiophanate-methyl and carbendazim. For the prevention and control of gray mold, spray 1000~2000 times of 50% wettable powder at the early flowering stage, full flowering stage, and fruiting stage; for the prevention and control of sclerotinia sclerotiorum, spray 1500~2000 times of 50% wettable powder at the early flowering stage and full flowering stage. It is a vegetable fungicide for protection The systemic fungicide has both protective and therapeutic effects, and the effect is obvious under low temperature and high humidity conditions. Used for rape, radish, eggplant, cucumber, cabbage, tomato, sunflower, watermelon, strawberry, onion, peach, cherry, flower, grape and other crops to prevent gray mold and sclerotinia and gray star disease, flower rot, Brown rot, vine blight, etc., can also be used to resist thiophanate-methyl and carbendazim.

Used to prevent and control diseases such as tomato gray mold in protected areas rape, cucumber sclerotium, grape, tomato, strawberry, cucumber gray mold, fruit tree brown spot, corn size spot, tomato early blight. |
production method | preparation method 1 is made of methyl α-chloropropionate, methyl α-methacrylate and 3, 5-dichloroaniline as raw materials. First, methyl α-chloropropionate and α-methyl methacrylate were reacted to prepare 1, 2-dimethylcyclopropane-1, 2-diformate methyl, and then hydrolyzed to obtain 1, 2-Dimethylcyclopropane-1, 2-dicarboxylic acid. The above products are reacted with 3, 5-dichloroaniline to synthesize promethaniline. Preparation method Ethyl diα-methacrylate reacts with ethyl α-chloropropionate, potassium butanol, sodium hydroxide and acetic anhydride to prepare 1, 2-dimethylcyclopropane -1, 2-dicarboxylic anhydride. Then add the benzene solution of 3,5-dichloroaniline dropwise, precipitate the intermediate, stir for 30min after dropping, debenzene under reduced pressure, add acetic anhydride and anhydrous sodium acetate to the residue, heat at 100 ℃ for 30-60min, remove acetic acid and excess acetic anhydride, wash with dilute sodium hydroxide and water, and dry to obtain Pythium. M. p.165 ~ 167 ℃. |
