Problems solved by technology

[0003] The dry suspension concentrate is used as an adjuvant for flumechlor propargyl. The current dry suspension concentrate of flumechlor propargyl is not effective in terms of drug efficacy due to the safety of the dosage, and the treatment efficiency for weed control is insufficient. The use is single, the control range of grass species is narrow, and the promotion value is not enough

Abstract

The invention discloses a flumioxazin dry suspending agent and a preparation method thereof. The flumioxazin dry suspending agent is prepared from, by weight, 15-85 parts of flumioxazin, 5-15 parts ofa surfactant, 1-3 parts of a defoaming agent, 2-8 parts of a dispersing agent and 4-12 parts of a disintegrating agent, with the balance being a filler. The flumioxazin dry suspending agent preparedby the method provided by the invention has excellent prevention and treatment effects on perennial broadleaf weeds such as morning glory, cirsium setosum and humulus japonicus in a corn field, and ishigh in weeding efficiency and quick in effect; and experiments prove that the flumioxazin dry suspending agent also has corresponding prevention and treatment effects on other weeds in other crop fields and is suitable for wide application.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a dry suspension concentrate of flufenazine propargyl and a preparation method thereof. Background technique [0002] Flurafen propargyl is a cyclic imide contact selective herbicide, an inhibitor of protoporphyrinogen oxidase, and is a herbicide absorbed by young shoots and leaves. It can effectively control 1-year-old broad-leaved herbicides as soil treatment Weeds and some gramineous weeds are easy to degrade in the environment and are safe to subsequent crops. Soybeans and peanuts have good resistance to them. Corn, wheat, barley, and rice have moderate tolerance. They are suitable for soybeans, Prevent and control annual broad-leaved weeds and some gramineous weeds in crop fields such as peanuts and orchards; [0003] The dry suspension concentrate is used as an adjuvant for flumechlor propargyl. The current dry suspension concentrate of flumechlor propargyl is not effec...
