ethyl N-(2,3-dihydro-2,2-dimeyhylbenzofuran-7-yloxycarbonyl(methyl)aminothio)-N-isopropyl-β-alaninate - Uses and synthesis methods
Toxicity
the acute oral LD50 of male rats is 138mg/kg, that of male mice is 175mg/kg, and that of dogs is 300mg/kg. The acute percutaneous LD50 of male rats is> 2000mg/kg. There is no irritation to rabbit skin, slight irritation to eyes, no sensitization to guinea pig skin, and no delayed neurotoxicity to hens. The 2-year feeding test for rats had no effect at a dose of 1.5 mg/kg per day. No mutagenicity, the Ames test was negative, the micronucleus test was negative, and the test showed no teratogenic or carcinogenic effects. Carp LC50 is 0.65mg/L (48h), Daphnia LC50>10mg/L (3h), and bee LD50 is 0.28 μg/animal.
use
Efficient, broad-spectrum carbamate insecticides that kill pests by inhibiting cholinesterase. It has the effects of contact, stomach poison and absorption, mainly stomach poison. Suitable for rice, corn, sugar beet, potato, cotton, fruit trees and other crops to control borers, brown planthopper, cotton aphid and other pests and nematodes. In addition, it has the characteristics of long duration and control effect on resistant pests. To prevent and control the dead heart and white ears caused by Chilo suppressalis and Chilo suppressalis, the drug can be used from the peak period of egg incubation to the peak period, and the application can be carried out with 5% Acrylic granules 300g/100m2. The control effect of brown planthopper was 90% when the rice was in booting stage and the third-year nymph was in full bloom stage. Control of cotton aphids in cotton seedling transplanting, with 5% granule 180~300g/100 m2, applied to the cotton plant hole.
can be applied as soil and leaf insecticides. Control of long horned leaf beetle, jumping armor, corn black unicorn fairy, apple stupid moth, potato beetle, golden needle worm, diamondback moth, rice weevil and aphids have high activity and long duration. Mainly control rice, cotton, corn, soybeans, vegetables and fruit trees of a variety of piercing mouth and chewing mouth pests.
Mainly used to control a variety of piercing and chewing mouthparts pests of rice, cotton, corn, soybeans, vegetables and fruit trees
