Rats 90d feeding Test No effect dose is 1800mg/kg feed, equivalent to 90mg/kg per day, dogs 1 year feeding Test No effect dose is 109mg/kg, the non-effective dose was 22mg/kg in the 2-year feeding test for rats and 9 mg/kg in the 2-year feeding test for mice. There was no teratogenic, carcinogenic and mutagenic effect under the experimental conditions. Carp, rainbow trout LC50>100mg/L (96H). Japanese quail and Peking duck LD50>2000mg/kg. Bee (oral or contact) LD50>100g/only (48h). |
Use | a sulfonylurea herbicide inhibits cell division and cell growth by inhibiting synthesis of valine and isoleucine. Hand growth stopped, 5~10D plants began yellowing, withering, death. It can be used for transplanting rice, direct-seeding rice and rice field to control annual Broad-leaved weeds and Cyperaceae weeds. For transplanting field in rice transplanting after 4 ~ 7d with 20% water dispersible granule 90~150g/hm2 (active ingredient 18 ~ 30g), leaf stem spray or spread poison soil (sand) after the treatment, the field water shall be maintained for 3-5 days, and the duck tongue grass, node vegetables, dipstick, eye vegetable, beef felt and three-male furrow shall be controlled. For direct seeding field, 7 ~ 15d after rice sowing, with 20% water dispersible granule 90~150g/hm2 (active ingredient 18 ~ 30g) for spraying or poison soil, field water shall be maintained for 3-5 days after treatment. Ethersulfuron-methyl can also be used to control general weeds and ferns in cocoa, rubber and palm plantations. ether xanthan is an insecticide. Suitable crops for Rice. |
production method | preparation of 2-methoxyethoxybenzenesulfonamide by reacting benzyl bromide with 2-chlorobenzenesulfonamide and ethylene glycol monomethyl ether, it is then hydrolyzed to give 2-methoxyethoxybenzenesulfonamide. Preparation of 2-methoxyethoxybenzenesulfonyl isocyanate 2-methoxyethoxybenzenesulfonyl isocyanate was prepared by reacting 2-methoxyethoxybenzenesulfonamide sequentially with methyl isocyanate and phosgene. Synthesis of ether sulphuron-methyl ether sulphuron-methyl ether was prepared by the reaction of 2-amino -4, 6-dimethoxy-1, 3, 5-triazine with 2-methoxyethoxy benzenesulfonyl isocyanate. |
