Micro-capsule suspending agent containing pendimethalin

Abstract

The invention discloses a micro-capsule suspending agent containing pendimethalin. The micro-capsule suspending agent is prepared by taking pendimethalin or a compound of the pendimethalin and an active component II as an active ingredient, and complementing to 100% by using a capsule wall material, an initiator, a promoter, a cosolvent and a solvent, wherein the active component II can be any one of alachlor, metolachlor, acetochlor, pretilachlor, propisochlor or butachlor or the like. The micro-capsule suspending agent can be used for prevention and treatment of annual and perennial weeds in sugarcane or corn fields, and has the advantages of long lasting period, high working efficiency, synergies, safety, environmental protection and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pendimethalin-containing microcapsule suspension. Background technique [0002] Pendimethalin (pendimethalin), also known as Shitianbu, Bicaotong, Pendimethalin, Shacaotong, Caicaotong, was first developed by the American Cyanoamide Company in 1972 (P), and the chemical name of the active ingredient is N- 1-(Ethylpropyl)2,6-dinitro-3,4-dimethylaniline. Pendimethalin is a selective systemic herbicide with poor conductivity. Pendimethalin does not affect the germination of weed seeds, but acts after the young shoots, stems and roots absorb the agent during the germination process of weed seeds. The absorption part of dicotyledons is the hypocotyl, and the monocotyledonous plants are young shoots. The symptoms of damage are that the young shoots and secondary roots are inhibited. The reason is that the protein synthesis of these plants is inhibited. Control effect. Suitable...

Problems solved by technology

Pendimethalin is a selective systemic herbicide with poor conductivity

Leaching has brought many problems to the use of herbicides: 1. Herbicides are leached downwards, resulting in poor weeding effect and easily causing residual groundwater pollution; 2. Through leaching, herbicides enter the soil layer of crop roots and cause Potentially selective herbicides damage crops; 3. Reverse leaching causes herbicides to move to the soil surface and be lost through volatilization

Due to their own physical and chemical properties, many pesticide active ingredients are difficult to process into environmentally friendly water-based preparations, and usually can only be processed into emulsifiable concentrates for sale. The extensive use of organic solvents has brought a great burden to the human living environment.

At the same time, the characteristics of organic solvents such as low flash point and low ignition point bring great inconvenience to storage and transportation.
