Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of weed resistance
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Abstract

The invention provides a forestry herbicide. The forestry herbicide comprises the following active ingredients in parts by weight: 1-10 parts of glufosinate and 1-20 parts of quizalofop-p-ethyl, wherein the active ingredients account for 50-95% by weight of the herbicide; the herbicide further comprises a functional auxiliary; and the functional auxiliary is one selected from a solvent, a dispersing agent, a penetrating agent, a wetting agent, a stabilizer, a defoaming agent and an anti-freezing agent.

Description

technical field [0001] The invention belongs to the field of chemical pesticides, in particular to a herbicide used for weeding in forestry. Background technique [0002] Weeds are the great enemy in forestry production, and they are very harmful to forest trees. They are called green "flames". According to estimates, due to the inability to remove weeds in time, the growth of trees will be reduced by more than 50% in the first three years, and even the whole plant will be bullied to death. In particular, the roots of some grass weeds secrete certain substances that inhibit the growth of trees. In addition, weeds are places where pests live, which can easily induce forest pests and damage tree growth. Weed damage is very serious in every link of forestry production and in the whole tree growth process. Therefore, to ensure the quality of forest trees and improve the survival rate, weeds must be removed in time to control the growth of weeds. [0003] Chemical weeding is ...
