preparation example Construction

[0052] The preparation method of the emulsifiable concentrate is as follows: according to the formula quantity, the alkaloid of sophora flavescens, the turpentine, the emulsifier, the organic solvent, the penetrant and the synergist are mixed, stirred evenly in the reactor, and the finished product is obtained after quality inspection.

[0053] The production method of the above-mentioned plant-derived synergistic compound aphid killing microemulsion is as follows: weigh the raw material formula, sequentially add and mix, stir transparently in the reactor, and finally make the finished product after quality inspection.

[0054] The production method of the above plant-derived synergistic compound aphidicide aqueous emulsion is as follows: weigh the raw materials according to the formula, sequentially add and mix them, and finally emulsify and disperse under the action of a high-speed shearing machine, and finally make a finished product after quality inspection.

Abstract

The invention discloses a sophora alopecuroides L alkaloid-containing plant-derived synergistic compound aphicide. The plant-derived synergistic compound aphicide is obtained by adding an aid into sophora alopecuroides L alkaloid and turpentine oil serving as major ingredients and compounding. A preparation is in the form of creaming agent, micro-emulsion and emulsion in water and contains 1.0 to20.0 percent of sophora alopecuroides L alkaloid, 5.0 to 40.0 percent of turpentine oil and the balance of aid. The compound aphicide is mainly applied to aphids such as myzus persicae, cabbage aphids, macrosiphoniella sanborni, medlar aphids and the like on fruit trees, vegetables and flowers. The plant-derived synergistic compound aphicide does not contain any chemical pesticide ingredient, haslow toxicity on human beings and livestock, is environmentally-friendly, can prevent and control various aphids on fruit trees, vegetables and flowers, has extremely high application value on the production of organic agricultural products and is an ideal novel nuisanceless aphicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to an aphidicide with two plant-derived substances of Sophora sophorae and turpentine as active components and a preparation method thereof, which is mainly used for preventing and treating aphids on fruit trees, vegetables and flowers. , cabbage aphid, chrysanthemum small long tube aphid and wolfberry aphid and other aphids. Background technique [0002] Aphids are important agricultural pests and have the characteristics of fast reproduction, large numbers, many types, severe damage and wide range of damage, so it is difficult to control them. At present, chemical agents are mostly used for the prevention and control of aphids. However, a large number of chemical drugs for a long time have led to the emergence of problems such as drug resistance, environmental pollution, and harm to human health. Searching for aphidicidal active substances from the treasure house of...
