Description

2-ethoxyethyl 2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenoxy)propanoate is a carboxylic ester that is the resulting from the formal condensation of the carboxy group of 2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenoxy)propanoic acid with the hydroxy group of 2-ethoxyethanol. It is an aromatic ether, an organochlorine compound, an organofluorine compound, a member of pyridines and a carboxylic ester. It derives from a 2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenoxy)propanoic acid and a 2-ethoxyethanol.

Haloxyfop-ethoxyethyl Use and Manufacturing

Heterocyclic oxyphenoxy fatty acid post-emergent selective herbicides, fatty acid synthesis inhibitors, with systemic conduction effect, stems and leaves are quickly absorbed by weeds and transmitted to the entire plant, hydrolyzed into acid, inhibit root and Stem meristem grows and causes death. It is used to control various broad-leaved crops such as soybean, cotton, peanut, rapeseed, nursery, flax and other broad-leaved crops, such as Madang, Maidengrass, Goosegrass, barnyard grass, Setaria, Qianjin, etc. annual grass weeds, bermudagrass, white grass, etc. Perennial grass weeds are not effective against broadleaf grasses and sedges. For example, in the field of rapeseeds, see the maidenhair, in 1 to 2 leafing stages, use 12.5% emulsifiable concentrate 4.5 to 7.5mL/100m2, spray treatment with 4.5kg of water on stems and leaves; to control weeds in soybean fields, restore 2 to 4 after soybean seedlings Leaf, weeds 3 to 5 leaf stage, use 12.5% emulsifiable concentrate 6 to 9 mL/100 m2, spray 4.5 kg of water, increase the dosage appropriately in drought; control peanut or cotton field weeds, at peanut 2 to 4 leaf stage, weed 3 to 5 leaf stage, cotton field weed 3 to 6 leaf stage, spray 4.5 kg of water with 12.5% EC 6 to 9 mL/100 m2.
