Abstract

The invention discloses a weeding composition and an application thereof, and relates to the pesticide compounding technical field. Effective ingredients of the weeding composition comprise a component A and a component B; the compound A is nicosulfuron or a salt thereof; the compound B is arbitrary one or more of flazasulfuron or salts thereof, and trifloxysulfuron or salts thereof; the weight ratio of the component A to the component B is (1-20):(20-1). The weeding composition has four advantages: 1, the composition can effectively reduce the application amount of single agents, is fast in quick-acting property and long in lasting period, and delays the drug resistance of plants; 2, the composition can efficiently prevent and remove older broadleaf weeds, sedge and gramineous weeds with 7 leaves or less, and has synergistic interaction effect; 3, the composition can expand the weeding spectra; and 4, the 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] Nicosulfuron, the English name is nicosulfuron, molecular formula: C 15 h 18 N 6 o 6 S, chemical name: 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfonyl)-N,N-dimethylnicotinamide, its structure is shown in formula (I). Nicosulfuron is a high-efficiency corn herbicide. It can effectively control a variety of annual g...
