Abstract

The invention belongs to the technical field of pesticides and particularly relates to a suspending agent and a preparation method thereof. The suspending agent is composed of, by weight percentage, 0.5-10% of emamectin benzoate, 2-15% of solubilizer, 1-3% of wetting agent, 2-4% of dispersing agent, 0.5-2% of antioxidant agent, 3-10% of drift control agent, 2-5% of antifreezing agent, 0.1-3% of thickener, 0.2-0.4% of defoamer, 0.1-0.5% of preservatives and water as balance. According to the suspending agent, the components synthesize to give stable play to the pesticidal effects of the emamectin benzoate and reduce the application cost; meanwhile, with no organic solvent, the suspending agent is safe during production and application and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a suspending agent and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of agricultural plant protection UAVs, nearly ten million acres of farmland have been sprayed with plant protection UAVs every year. The mechanization and automation of plant protection pesticide application has played an important role, which can effectively save agricultural costs and improve the efficiency of prevention and control. In actual aerial control operations, in order to meet the needs of specialized unified control of pests and diseases, it is often necessary to mix different active ingredients, different dosage forms, and different contents of preparations in tanks, and the total amount of diluted agents for conventional low-altitude drone spraying is not required. If it exceeds one kilogram per mu, it belongs to low-volume ...
