Abstract

The invention discloses a herbicide composition and an 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 the component (A) is agroxone or a derivative thereof, the component (B) is arbitrary one of flazasulfuron, pyrazosulfuron-ethyl, halosulfuron-methyl and trifloxysulfuron, and the weight ratio of the component (A) to the component (B) is 1:70-70:1. The herbicide composition has four characteristics that 1, the herbicide composition is capable of effectively lowering the application amount of each single agent 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 preventing and eliminating elder broadleaf weeds, sedges or grassy weeds with the leaf number of 7 or less and has the synergistic interaction; 3, the herbicide composition is capable of expanding a weed control spectrum, and especially is capable of preventing and eliminating sweet clover and other difficult-to-control leguminous weeds; and 4, the herbicide composition is highly safe to lawns. The herbicide combination is used for prevention and cure of lawn weeds for the first time.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and relates to a herbicide composition and its application, in particular to a herbicide composition composed of 2-methyl-4-chlor or its derivatives and pyrazosulfuron-methyl, pyrazosulfuron-methyl, and chlorpyrazosulfuron-methyl A herbicide composition and application thereof in which any one of trifloxysulfuron-methyl is an active ingredient. 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] 2M4Cl or its derivatives are phenox...
