Abstract

The invention provides a weeding composition and application thereof and relates to an oil suspending agent containing glufosinate, sulfentrazone and halosulfuron-methyl. The weeding composition is characterized by being composed of the following components: 1-20% of glufosinate, 5-10% of sulfentrazone, 0.1-5% of halosulfuron-methyl, 3-20% of an emulsifying agent, 1-5% of a dispersing agent, 1-5% of a structure modifier, 1-5% of an antifreezing agent and the balance of carrier oil. The oil suspending agent provided by the invention is reasonable in components, good in wettability and rain wash resistance, pollution-free to the environment, safe to people and animals, obvious in synergistic effect and especially applicable to prevention or killing off of weeds difficult to control such as cyperus rotundus and difformed galingale herbs, so that the oil suspending agent provided by the invention is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to an oil suspension containing glufosinate-ammonium, sulfentrazone and chlorpyrazosulfuron-methyl. Background technique [0002] Glufosinate ammonium (Glufosinate ammonium), CAS registration number: 77182-82-2, can be used to control annual and perennial dicotyledonous and gramineous weeds, such as acanthus, crabgrass, barnyardgrass, foxtail, wild wheat, etc. [0003] Sulfentrazone, also known as sulfonyl triazolone, has a CAS registration number of 122836-35-5 and its structural formula is as follows: [0004] [0005] Sulfentrazone is a triazolinone herbicide developed by FMC Corporation, a protoporphyrinogen oxidase inhibitor, which causes cell membrane damage by inhibiting protoporphyrinogen oxidase in the process of chlorophyll biosynthesis, causing leaves to dry up and die quickly . Used to control annual broad-leaved weeds, gramineous weeds and sedges such as morni...
