Problems solved by technology

Since mites are mostly concentrated on the back of plant leaves, it is not easy to directly contact with the liquid medicine, so the control effect is affected. The solution is to develop new compounds with high activity, but this method requires a huge investment of time and money, and the new activity The development of ingredients often cannot catch up with the emergence of pest mite resistance, so it is a more economical way to develop new compound formulations with synergistic effects

Abstract

The invention discloses an agricultural acaricide composition containing active components composed of doramectin and bifenazate. The weight ratio of the active components is (1:80)-(80:1), is preferably (1:40)-(40:1) and further preferably (1:16)-(15:1). The composition disclosed by the invention can be prepared into a pesticide acceptable dosage form together with an appropriate aid, and the appropriate dosage form is wettable powder, water-dispersible granules and a water emulsion. The composition realizes reasonable matching of the components, thereby mutually making up the defect during use of a single agent; the composition has a favorable acaricide effect, a long lasting period, a favorable fast-acting property and a synergic effect; the composition is safe to the environment and low toxic to humans and animals; and the composition has favorable application prospects in the aspect of pesticide mixture development.

Description

technical field [0001] The invention relates to an agricultural acaricidal composition containing doramectin and bifenazate, which is used for preventing and controlling harmful mites on citrus, apple, cotton and other crops in agricultural production, and belongs to the technical field of compound pesticides. Background technique [0002] Doramectin (doramectin) is a new type of macrolide antibiotics, which is fermented by genetically recombined Streptomyces avermitilis strains. The release of aminobutyric acid interferes with normal neurophysiological activities. It is an efficient and broad-spectrum insecticide, especially for mites with efficient stomach poisoning and contact killing effects, and has a weak fumigation effect without systemic properties. No control effect on eggs. Doramectin has a strong penetrating effect on the leaves, a long residual effect period, is less affected by rain, and is safe for crops. Since biological source pesticides are all isolated fr...
