AI Technical Summary

Problems solved by technology

But, suspending agent also has many deficiencies: first, suspending agent is a dynamic unstable thermodynamic solid-liquid dispersion system, as time goes by, the solid particles in the system are easy to coagulate or settle mutually, therefore, the long-term of suspending agent Physical stability has always been the key to improving the quality of suspension concentrate preparations
Compatibility test should be done in advance for the unsure tank mix, the use process is complicated and brings a lot of inconvenience to the operator

Abstract

The invention provides an insecticidal suspending agent containing dinotefuran. The suspending agent is characterized by being prepared from the following components in mass percentage: 1-30% of the dinotefuran, 0.1-35% of a second active component, 3-9% of a wet dispersant, 0.1-0.5% of a de-foaming agent, 1-6% of an anti-freezing agent, 0.1-4% of a thickening agent, 0.1-0.5% of a preservative, 0-2% of a pH (Potential of Hydrogen) adjusting agent, 0-2% of an antioxidant, 0.5-5% of a functional auxiliary agent and the balancing being water, wherein the second active component is one of bifenthrin, imidacloprid, methylamino abamectin benzoate, cyhalothrin, thiamethoxam, indoxacarb, chlorfenapyr, acetamiprid and ethiprole. According to the insecticidal suspending agent, special components are selected and the content of each component is strictly limited; and the prepared insecticidal suspending agent has the very good fast-acting property and lasting period and has the very good prevention effect on tea lesser leafhopper, aleyrodid, thrips, aphids and the like. After the functional auxiliary agent is added, the insecticidal efficacy is improved by 10-12% when being compared with a medicament which is not added with the functional auxiliary agent.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing dinotefuran; the invention also relates to a method for preparing the pesticide composition. Background technique [0002] Stabbing mouthpart pests Aphids, whiteflies, and leafhoppers are the main pests that harm the leaves, stems, and flowers of crops such as fruit trees, flowers, tea, and solanaceous vegetables. For a long time, the main chemical drugs used to prevent and control such pests are fendilin, acetamiprid, imidacloprid, actetide, etc. Due to the emergence of resistance, these agents with good control effects in the past have been used for many years for a long time, and the effect has obviously deteriorated. ; Along with the continuous development of new varieties of pesticides, dinotefuran, ethiprole and other new drugs with high activity, low residue and good safety to humans and animals have been born. [0003] Dinotefuran (chemical n...
