Spray aid for agricultural aviation plant protection spray or ultra-low-capacity spray and application

Abstract

The invention discloses a spray aid for an agricultural aviation plant protection spray or an ultra-low-capacity spray, a preparation method and application, and belongs to the technical field of pesticide preparations. The spray aid consists of plant oil or modified plant oil, an emulsifier, a wetting agent, an adhesive and a pH value adjusting agent. Due to addition of the spray aid, moisture evaporation of medicinal fog drop can be reduced, the particle size of the fog drop can be increased, and the adhesion property of the fog drop can be improved, so that fog drop shifting in the aerial spray process can be effectively reduced, and target fog drop numbers can be increased; and as wax coats of plant leaves or insect body surfaces have hydrophobicity and the plant oil or modified plant oil is adopted as a main component of the spray aid, absorption of pesticides on plant leaves or in insect bodies can be promoted, and the purposes of reducing the amounts of pesticides, increasing the utilization rates of the pesticides and improving the pesticide effects can be finally achieved.

Description

technical field [0001] The invention relates to a spray adjuvant used in agricultural aviation plant protection or low-capacity spraying, in particular to a spray synergist added in the mixing process of medicinal liquid. 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. Compared with the usual artificial spraying, aerial plant protection has the characteristics of fast, efficient, flexible and strong assault. It has developed rapidly in the United States, Japan and my country. However, the aerial plant protection is about 1 to 15 meters away from the crops or trees when spraying. During the falling process, the fog droplets will drift due to the influence of the wind, deviate from the designated target or stay in the air, and at the same time, the fog droplets that reach the surface o...
