Description
Technical Field
The invention relates to a pesticide synergistic composition applied to prevention and treatment of red spiders, belonging to the technical field of pesticide application.
Background
In recent years, the drug resistance of red spiders is getting larger and larger, the application level of field pesticides is higher in many areas, the use rate of the pesticide is increased year by year, but the outbreak trend of the red spiders is more and more obvious, and the control effect is reduced year by year. More than 70 percent of pesticide preparation can not play due role even reaching 95 percent of pesticide after being sprayed in the field. And the inactive pesticide is lost and volatilized, so that the pollution to the atmosphere, soil, water quality and even the whole ecological environment is caused. The pesticide synergist can achieve the purposes of remarkably improving the utilization rate of the pesticide and reducing the utilization rate of the pesticide field.
Calycosin is one of the main representative components of isoflavone compounds in Astragalus membranaceus. The isoflavone components have effects of regulating immunity, resisting oxidation, resisting mutation, etc. At present, isoflavone compounds also have application in the agricultural field. Patent CN202010683834.2 reports the use of two isoflavonoids in controlling plant diseases.
Phospholipids are widely distributed in the animal and plant kingdom, are natural biosurfactants, and are also constituents of cell membranes of human and animal and plant tissues. The soybean lecithin is used as a natural surfactant with good performance, has the effects of emulsification, softening, wetting, dispersion, permeation, solubilization, defoaming, antioxidation and the like due to the specific chemical structure, and is widely applied to the industries of food, medicine, cosmetics, textile, leather making, feed and the like.
The hydroxylated soybean phospholipid is a phospholipid with high dispersibility in water, and is prepared by stirring and reacting hydrogen peroxide and phospholipid in the presence of weak acid (lactic acid or acetic acid) at 50-70 deg.C for 1 hr. Hydroxylated soybean phospholipid has light color and good fluidity, HLB value can reach 9-10, and amino group of hydroxylated soybean phospholipid is also changed, so that the hydroxylated soybean phospholipid can be well dispersed in cold water, and is widely used as industrial emulsifier, such as leather, cosmetics, paint and the like. The research of the invention discovers that the calycosin glycoside and the hydroxylated modified soybean phospholipid can show the super insecticidal activity to the red spiders when being compounded and used according to a specific proportion.
