Problems solved by technology

At present, chemical agents are mostly used in the prevention and treatment of aphids. However, a large number of chemical drugs for a long time have led to problems such as drug resistance, environmental pollution, and harm to human health; Apply oil or vaseline on the board to remove the aphids that fall on the surface. This method is simple and convenient for small-scale use, but it is not conducive to large-scale production, and the effect is not obvious enough.

Abstract

The invention discloses a plant-sourced synergic compound insecticide containing tea polyphenol and dioscin and a preparation method of the plant-sourced synergic compound insecticide. The preparation method comprises the steps of adding auxiliaries into tea polyphenol and dioscin, wherein tea polyphenol and dioscin are used as main components; and compounding to obtain the plant-sourced synergic compound insecticide. The preparation is environment-friendly emulsified oil or emulsion in water; and the preparation contains 1.0-10.0% of tea polyphenol, 20.0-50.0% of dioscin and the balance of the auxiliaries. The insecticide contains no any chemical pesticide components, is nontoxic to people and livestock, environment-friendly and incapable of easily generating drug resistance of insects, is easily degraded and is mainly applied to prevention and control of aphid diseases such as cotton aphid, macrosiphoniella sanborni, macrosiphum rosivorum and aphis citricola on flowers so as to have extremely high application and popularization values, so that the insecticide an ideal novel pollution-free insecticide.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and in particular relates to a botanical synergistic compound insecticide containing tea polyphenols and dioscin and a preparation method thereof. Background technique: [0002] Aphids belong to the family Aphididae of the order Aphididae, commonly known as honey bugs, putty insects, etc., and are important pests that endanger the growth of flowers. They have the characteristics of various types, rapid reproduction, huge numbers, serious damage and wide range of damage, and there are certain difficulties in prevention and control. At present, chemical agents are mostly used in the prevention and treatment of aphids. However, a large number of chemical drugs have caused problems such as drug resistance, environmental pollution, and harm to human health for a long time; Apply oil or vaseline on the board to remove the aphids falling on the surface. This method is simple and convenient for small...
