Abstract

The invention belongs to the technical field of weed killer research and development and particularly relates to a weeding composition containing flufenacet and bentazone and an application of the weeding composition. The weeding composition for post-emergence of the corn is characterized in that flufenacet and bentazone are taken as effective ingredients and are in a mass proportion of 1-60:1-60. The weeding composition can be used for weeding for post-emergence of the corn and has remarkable effect especially in preventing and removing broadleaved weed and sedge weed in corn fields; compared with single pesticide, the weeding composition has the advantages that on the premise of improved efficacy, weed resistance is delayed, weed control spectrum is wide, lasting period is long, and safety is achieved for the corn and succession crops.

Description

technical field [0001] The invention belongs to the technical field of herbicide research and development, in particular to a herbicidal composition containing flufenacet and bentazone and its application. Background technique [0002] Flufenacet (Flufenacet), molecular formula: C 14 h 13 f 4 N 3 o 2 S, chemical name: 4`-fluoro-N-isopropyl-2-[5-(trifluoroglycoside)-1,3,4-thiadiazo-2-imine]acetamide. Flufenacet mainly acts by inhibiting cell division, and is mainly used for the pre-emergence and post-emergence early stages of some broad-leaved weeds in corn, wheat, barley, soybean and other crop fields. weeding. [0003] Benazone, also known as paicaodan, bentazon, chemical name: 3-isopropyl-(1H)-benzo-2,1,3-thiadiazin-4-one-2,2-dioxide It belongs to benzothiadiazinone herbicides, and its structural formula is: [0004] [0005] Benazone is a photosynthesis inhibitor, a contact-type selective post-emergence herbicide, used for stem and leaf treatment at the seedlin...
