Quizalofop-P-tefuryl 喹禾糠酯
Introduction: Quizalofop-P-tefuryl is having selective post-emergence herbicidal effect on annual and perennial grasses in potato, soybean, sugar beet, peanut, oilseed rape, sunflower, vegetable crops, etc. Quizalofop-p-tefuryl (belonging to aryloxyphenoxypropionate) acts as systemic herbicide, absorbed from the leaf surface and translocates throughout the plant.

ENVIRONMENTAL FATE
Animals Extensively degraded by hydrolysis, hydroxylation and conjugation. Plants Rapidly hydrolysed to quizalofop. Soil/Environment DT50 1.9-22.0 h.
Usage: Quizalofop-P-tefuryl was introduced by Uniroyal Chemical Co., Inc. (now part of Crompton Corp.). It is a herbicide for the control of annual grass and broad-leaved weeds in a variety of crops.
Application: Biochemistry Fatty acid synthesis inhibitor (inhibition of acetyl CoA carboxylase) Mode of action Systemic herbicide, absorbed from the leaf surface, with translocation throughout the plant, moving in both the xylem and phloem, and accumulating in the meristematic tissue. Uses Control of annual grasses such as Avena fatua and Alopecurus myosuroides, and perennial grasses such as Sorghum halepense and Elymus repens, in potatoes, flax, oilseed rape, peas, sugar beet, cotton, and soya beans. Applied at 30-240 g/ha.
