Abstract

The invention belongs to the technical field of pesticides and discloses a mixed herbicide containing sulfentrazone and quizalofop-p-ethyl. The sulfentrazone and the quizalofop-p-ethyl are employed in the herbicide as main active components according to the mass ratio of 0.1-80:0.1-80. The mixed herbicide can be applied for weeding fields of sugarcanes, corns, soybeans, peanuts, citrus, sorghums and sunflowers, safe and environment-friendly, and is an excellent chemical herbicide for the sugarcanes, corns, soybeans, peanuts, citrus, sorghums, sunflowers, and the like crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a mixed herbicide containing sulfentrazone and quizalofop-p-ethyl. The herbicide composition can be applied to pre-emergence or post-emergence weeding of sugarcane, corn, soybean, peanut, citrus, sorghum, and sunflower. Background technique [0002] Sulfentrazone, molecular formula: C 11 h 10 Cl 2 f 2 N 4 o 3 S, chemical name: 2',4'-dichloro-5'-(4-difluoromethyl-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-tri Azol-1-yl) methylsulfonylanilide, also known as: methylsulfonylanilide. Sulfentrazone is a triazolinone herbicide, which belongs to protoporphyrinogen oxidase inhibitor. By inhibiting protoporphyrinogen oxidase in the process of chlorophyll biosynthesis, excessive protoporphyrin IX is produced in plant cells, which is Photosensitizers lead to the production of reactive oxygen species in cells, which eventually lead to the rupture of...
