Abstract

The invention discloses a herbicide composition and application thereof and relates to the technical field of pesticide compounding. The herbicide composition is prepared from the following effective components including a component A and a component B, wherein A is fazasulfuron or a salt thereof, B is at least one of fenoxaprop-p-ethyl and metamifop, and the weight ratio of the component A to the component B is (50-1) to (1-50). The herbicide composition has four characteristics that 1, the herbicide composition is capable of effectively lowering the application rate of each single dose and delaying the drug resistance of a plant and is fast in quick action and long in persistent period; 2, the herbicide composition is capable of efficiently controlling and eliminating elder broadleaf weeds, sedges and grass weeds with the number of leaf less than 7 and has the synergistic interaction; 3, the herbicide composition is capable of expanding a weed control spectrum; 4, the herbicide composition is highly safe to lawns.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and relates to herbicidal composition and application thereof. Background technique [0002] With the rapid development of the economy, people have higher and higher requirements for urban greening, and the domestic lawn area is also increasing. The prevention and control of weeds in the lawn has become the biggest problem for lawn managers. Most of the weeds in the lawn are manually pulled out now, and the investment is large, the efficiency is low, and the effect is poor. Spraying safe and effective herbicides is an effective measure to control lawn weeds. [0003] Flazasulfuron, English name is flazasulfuron, chemical name is 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-trifluoromethyl-2-pyridinesulfonyl)urea, molecular weight is 407.32, the chemical formula is C 13 h 12 f 3 N 5 o 5 S, its structure is shown in formula (I). The drug can be quickly absorbed by the stems, leaves an...
