Problems solved by technology

Atrazine can control a variety of annual gramineous and broad-leaved weeds. It is suitable for dry field crops such as corn, sorghum, sugarcane, fruit trees, nurseries, woodlands, etc. to control crabgrass, barnyardgrass, foxtail, sedge, apricot, Polygonum, Chenopodium, cruciferous, and leguminous weeds, but with the increase of the application period, the resistance of weeds to single herbicides gradually increases. If we want to achieve a good weeding effect, we need to increase the dosage, which not only increases the cost , but also increase the residues of chemicals in the environment, polluting the environment
Nicosulfuron also appears to have the same drawbacks

Abstract

The invention provides a composition of an atrazine-containing weeding suspending agent. The suspending agent comprises the following active ingredients in percentage by mass: 10-40 percent of atrazine, 1-10 percent of nicosulfuron, 5-30 percent of 2-methyl-4-chloro-isooctyl and the balance of aids. According to the suspending agent disclosed by the invention, the atrazine, nicosulfuron and 2-methyl-4-chloro-isooctyl are used according to compatibility of medicines, thus the drug effect can be improved, the drug dosage is reduced, the economic cost is reduced, the application dosage of each active material is greatly reduced, and residues of agents in the environment are reduced. Meanwhile, resistance of weeds to herbicides can be delayed, the service lives of the agents are prolonged, and the suspending agent has important ecological significance and environment protection significance.

Description

technical field [0001] The invention belongs to the field of herbicides and relates to a herbicide suspension, in particular to an atrazine-containing herbicide suspension and a preparation method thereof. Background technique [0002] Currently commonly used post-emergence herbicides are mainly atrazine and nicosulfuron. Atrazine is a broad-spectrum systemic herbicide that is mainly absorbed through roots and is widely used in corn fields, soybeans and other farmlands. . Atrazine can control a variety of annual gramineous and broad-leaved weeds. It is suitable for dry field crops such as corn, sorghum, sugarcane, fruit trees, nurseries, woodlands, etc. to control crabgrass, barnyardgrass, foxtail, sedge, apricot, Polygonum, Chenopodium, cruciferous, and leguminous weeds, but with the increase of the application period, the resistance of weeds to single herbicides gradually increases. If we want to achieve a good weeding effect, we need to increase the dosage, which not onl...
