Problems solved by technology

[0003] In order to solve the problem that there is a lack of aviation-specific agents in the current market and conventional pesticides are not suitable for aerial spraying, the present invention provides a pesticide suspension used in low-volume spraying of agricultural aviation and its preparation method; the suspension does not contain volatile organic compounds. Compound (VOC), which reduces the pollution of volatile substances to the atmosphere during the spraying of pesticides; the particle size is smaller than that of conventional pesticide suspensions, which improves the uniformity and absorption rate of pesticides on the target surface

Abstract

The invention discloses an aviation low-dosage spray insecticidal suspension agent and a preparation method and application method thereof, and belongs to the technical field of pesticide. The suspension agent is composed of the following components: in parts by weight, 0.01-8 parts of a pesticide active compound, 5-15 parts of an evaporation drift inhibitor, 1-10 parts of a dispersing agent, 1-10parts of a wetting agent, 0.1-2 parts of a defoaming agent, 0.1-2 parts of a binder, 1-5 parts of a grinding aid and 50-100 parts of water, wherein the evaporation drift inhibitor includes polysaccharide and oil, the dispersing agent includes a nonionic surfactant and an anionic surfactant, and the nonionic surfactant comprises hydroxyl-terminated hyperbranched polyester; and the grinding aid isone or more of triethanolamine, diethanol monoisopropanolamine and polyisopropanolamine. The aviation low-dosage insecticidal suspension agent has a simple preparation method and an application method, and has the advantages of no volatile organic solvents, smaller particle size than conventional suspension agents, low surface tension and the like.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an aerial low-volume spray insecticide suspension and its preparation and use method. Background technique [0002] Agricultural aviation plant protection is the use of aircraft to spray pesticides or fertilizers to prevent and control diseases, insects, and weeds in farmland, forests, and grasslands, or to manage field growth. During the aerial plant protection spraying process, since the amount of liquid sprayed per mu is 0.5-1.5L, the dilution concentration of pesticides is about 15 times higher than that of manual or mechanical spraying on the ground, and the requirements for the formulation and quality of pesticides are also correspondingly increased, requiring the use of special pesticides. At present, the lack of special chemicals for agricultural aviation spraying in my country has become an important factor restricting the development of my country's agricultural aviation plant...
