Abstract

The invention relates to an amino acid water-base herbicide for low-capacity spraying. The herbicide is characterized by consisting of the following components in percentage by mass: 10-50% of an active herbicide component, 1-15% of a surfactant, 1-15% of a synergist, 0.05-20% of a humectant, 0.02-3% of a shifting control agent, 0.02-0.08% of a defoaming agent and the balance of water. When the herbicide is used in low-capacity spraying, the utilization rate of the medicine can be improved, the effect in weeding is improved, and meanwhile the working intensity is alleviated, the herbicide can be sprayed with 0.4 hour for each mu of land, the particle size Dv50 of fogdrop when the herbicide is subjected to low-capacity spraying can be 190-200 micrometers, and application risk caused by shifting is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a water-based herbicide for low-capacity spraying and its preparation. Background technique [0002] At present, chemical weeding has become an important measure for weed control in agricultural production, and has also improved agricultural production efficiency, especially the application of amino acid herbicides glyphosate and glufosinate-ammonium, which has changed the pattern of agricultural weeding. However, in actual use, chemical weeding requires a large amount of water as a dispersed carrier, and farmers have to carry tens of kilograms of diluted liquid to work in the field, which greatly increases the labor intensity of farmers and greatly reduces labor efficiency. and areas where operations are difficult appear more prominent. At the same time, when conventional herbicide products are used for spraying operations, the herbicide drift phenomenon is serious, and the ...
