Problems solved by technology

[0005] Long-term use of a single dose of abamectin may lead to the occurrence of resistance and the decline in drug efficacy. The content of a single dose has also grown from 0.1% in 2000 to the current 8%. Serious, thereby causing environmental pollution to increase, problems such as crop residues exceeding the standard, the environmental protection high-efficiency low toxicity that the present invention proposes, the low-residue acaricidal composition, by compounding abamectin and spirodiclofen into a microcapsule suspension, Microcapsule suspension-suspension agent, used to control harmful mites on wheat, vegetables, cotton, and fruit trees. It has a unique effect, is environmentally friendly and safe, and has a long-lasting effect

Abstract

The invention discloses a high-efficiency environment-friendly pesticide complex composition with a preparation form of microcapsule suspension preparation or microcapsule suspension-suspension preparation. The composition comprises, by weight, 0.5-6% of avermectin, 3-40% of spirodiclofen, and balance of auxiliary agents and a filling material. With the pesticide provided by the invention, various mite infestations can be controlled. The pesticide has the advantages of environment friendliness, sustained release, long effect duration, enhanced adhesion force, enhanced penetration, and no phytotoxicity.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to an environment-friendly and high-efficiency pesticide compound composition. The formulation of the composition is a microcapsule suspension or a microcapsule suspension-suspension. Background technique [0002] Spirodiclofen chemical name: 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro[4,5]-dec-3-en4-yl-2,2 -Dimethylbutyrate, molecular formula: C 21 h 24 Cl 2 o 4 , Spirodiclofen belongs to tetronic acid acaricides, has a new mechanism of action, has contact killing effect, and has no systemic property. It mainly inhibits the fat synthesis of mites and blocks the energy metabolism of mites. It is effective at all developmental stages of mites, including eggs, and is especially effective for all kinds of harmful mites. [0003] Abamectin is a highly efficient and broad-spectrum antibiotic insecticide and acaricide. It is composed of a group of macrolide compounds, the active substan...
