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.

Abstract

The invention discloses a microcapsule suspending-suspending agent containing pendimethalin. For the microcapsule suspending-suspending agent, pendimethalin and an active component II are compounded into active ingredients, and a capsule wall material, an initiator, an addition agent, a cosolvent and a solvent are added for reaching 100%, wherein the active component II is atrazine, or ametryn, or simazine. The microcapsule suspending-suspending agent containing pendimethalin can be used for preventing and controlling diseases of sugarcane, corn, broomcorn, and annual gramineae and broadleaf weeds in orchard garden, and the has the advantages of being long in lasting period, high in efficiency, capable of realizing synergistic interaction, safe and environment-friendly, and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pendimethalin-containing microcapsule suspension-suspension agent. Background technique [0002] Pendimethalin (pendimethalin), also known as Shitianbu, Bicaotong, Pendimethalin, Shacaotong, and Caicaotong, was first developed by the American cyanamide company in 1972 (P). 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 e...
