Abstract

The invention discloses a special water-soluble colloid agent for dripping persimmon tree trunk, and a preparation method thereof, and relates to the technical field of persimmon tree insect pest prevention, wherein the raw materials comprise, by weight, 5-30% of a natural polymer material, 1-15% of a synergist, 3-24% of a solvent, 0.3-10% of a surfactant, 1-10% of a non-polluting insecticide, 0.3-5% of an anti-freezing agent, and the balance of water, wherein the natural polymer material is potassium alginate, the surfactant is one or a plurality of materials selected from a series of Tween emulsifiers, the synergist is the composite extraction liquid of ailanthus altissima leaf, hot pepper and artemisia argyi, and the non-polluting insecticide is one or a plurality of materials selected from an efficient cypermethrin raw drug, an acetamiprid raw drug, and a phoxim raw drug. According to the present invention, the effect can be lasted for a year after the special water-soluble colloid agent is used, such that the insecticide consumption can be reduced, the prevention and control effect is good, the labor and the time can be saved, and the yield and the quality of the persimmon tree fruit are improved; the wood part is not damaged after the dripping; the special water-soluble colloid agent has good environmental compatibility and is safe to human and animals; and the preparation method has characteristics of simple preparation steps and mild preparation condition.

Description

technical field [0001] The invention relates to the technical field of pest control for persimmon trees. Background technique [0002] Trunk drip application is a kind of method that relies on the transpiration force of the tree itself to input nutrients, growth regulators, pesticides or other substances into the tree, so as to achieve the purpose of preventing and controlling diseases and insect pests, strengthening nutrition, correcting deficiencies, and regulating plant growth. method, which originated from the pesticide injection theory proposed in Muller's "Inner Plant Therapy" published in 1926. After nearly a century of theoretical research and application, the theory of dry injection and pesticide application has been perfected day by day. But along with the deepening of the research, the inventors found that the difference between the forest species, between the tree species and between the instillation formulations in the same insecticide will affect the absorptio...
