Suspending agent containing spirodiclofen and preparation method thereof

Abstract

The invention discloses a suspending agent containing spirodiclofen, comprising the following components by weight percent: 1-50% of spirodiclofen, 1-50% of another active matter, 2-10% of dispersant,0-5% of wetting agent, 0.1-6% of functional assistant, 0.01-0.8% of defoamer, 0-10% of antifreezing agent, 0.1-5% of thickening agent, 0-0.8% of mildew preventive, 0-2% of pH regulator, 0-3% of antioxidant and the balance of water. The functional assistant is one or the composition of alkyl butanedioic acid sulphonates, branched alkyl polyethenoxy ethers and linear alkyl polyethenoxy ethers. Compared with the prior art, the invention employs the method of adding a synergistic assistant in the manufacturing process of the suspending agent to reduce the operation steps in the use process of thepesticide so as to save the packing materials and prevent the addition of the functional assistant from destroying the stability of the suspending agent. Furthermore, since some functional assistantshave the dispersity and the wettability to some extent, the addition of the functional assistant increases the effect and the stability of the suspending agent.

Description

technical field [0001] The invention relates to a synergistic suspending agent of a pesticide composition containing spirodiclofen and a preparation method thereof. Background technique [0002] Acarids are the main pests that harm plant leaves, stems and flowers on fruit trees, cotton, solanaceous vegetables, ornamental flowers and other crops. Acarids have many generations, strong fecundity, and are prone to resistance to acaricides. Some acaricides with good control effects have become significantly less effective after years of long-term use. Spirodiclofen is a new acaricide with a new mechanism of action. It mainly inhibits the fat synthesis of mites and blocks the energy metabolism of mites. It is effective on all developmental stages of mites including eggs. It has contact killing effect and has no systemic effect. It has no cross-resistance with existing acaricides, and is suitable for controlling mites that are resistant to existing acaricides. Spirodifen has a wi...

Problems solved by technology

Usually people use the method of tank mixing, but if it is used improperly in the process of tank mixing, a series of problems such as ratio control and stability damage of the preparation will appear, and sometimes the synergistic effect cannot be produced or even the efficacy of the drug will be reduced.
