Problems solved by technology

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 prop...

Abstract

The invention discloses a micro-capsule suspension-suspending agent containing atrazine. The 100% of micro-capsule suspension-suspending agent comprises an active ingredient and the balance including a capsule wall material, an initiator, an auxiliary agent and a solvent, wherein the active ingredient is prepared by compounding the atrazine and an active ingredient II. The active ingredient II is one of alachlor, metolachlor, acetochlor, pretilachlor, propisochlor or butachlor. The micro-capsule suspension-suspending agent containing the atrazine is suitable for target crops including corns, sugarcanes, cotton, garlic, gingers, apples, bananas, citrus, hawthorns, peaches and the like, is used for preventing and controlling annual gramineous weeds, parts of broadleaf weeds and sedges, and has the advantages of being long in efficacy duration, high in work efficiency, good in synergistic effect, safe, environment-friendly and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an atrazine-containing microcapsule suspension-suspension agent. Background technique [0002] Alachlor, metolachlor, acetochlor, pretilachlor, metolachlor, butachlor, etc. are amide herbicides, which are mainly used in soil treatment to prevent and control grass weeds; Various dosage forms of single agent and compound agent such as emulsifiable concentrate, water emulsion, microemulsion, wettable powder, etc. [0003] Atrazine is a Sanqin herbicide, pre-emergence and post-emergence herbicide. Mainly used in corn, sugarcane, sorghum, tea tree and orchard woodland to control annual gramineous weeds and broad-leaved weeds. It has inhibitory effect on perennial weeds propagated by rhizomes or root buds. At present, there are various dosage forms of single agent and compound agent such as suspension concentrate, wettable powder, water dispersible granule, suspoemulsion, etc. on...
