Embodiment Construction

[0009] 1. Extraction of alkaloids: using normal temperature cell wall breaking and ultra-fine crushing technology, the plant raw materials containing alkaloids are crushed to more than 600 meshes, acetone is added to extract at room temperature, and the extract is separated and concentrated to a certain concentration for later use;

[0010] 2. Concentration by weight of each extract: 0.3% of picrogenetic alkali, 0.15% of nicotine, 0.2% of bovine heart pod, 0.1% of kulian fruit, 0.1% of kulianpi, 0.12% of pyrethrum chrysanthemum, 0.12% of centipede, thyme 0.15%; the mixing ratio of each extract: picrine 200Kg, nicotine 140Kg, beef heart pod 200Kg, kulianguo 80Kg, kulianpi 80Kg, pyrethrum 100Kg, centipeda 100Kg, thyme 100Kg;

[0011] 3. Add additives according to the following ratio: the weight of additives added per ton of the above mixed solution is: turpentine: 80Kg, ketone: 100Kg, emulsifier: 160Kg, penetrant: 160Kg, emulsifier OP-10, penetrant The agricultural penetrating a...

Abstract

The invention is a harmless high-efficient vegetative pesticide, which is composed of active ingredient and aid, wherein the active ingredient is mainly composed of matrine, and the aid is composed of Cymanchum komarovii extract, nicotine, bitter fruit, bitter orange peel, pyrethrum, radix stemonae stemona, and thyme extract. Usually, the medicine effect release of the vegetative pesticide is slower than the chemical pesticide and the vegetative pesticide has low knock down rate, which can be solved by using the invention. In the invention, the knock down time is shortened to 6 hours, and the effect of the vegetative pesticide is better than the chemical pesticide. The invention is provided without harm to human, animal, and crop, pesticide residue, environmental pollution, and 'three genicity' to human body (deformity, cancer, and mutation).

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, in particular to a pollution-free and high-efficiency botanical pesticide. Background technique: [0002] Ningxia and the arid regions of western China have unique and abundant plant resources such as Sophora sophora and Niuxinpuzi. In recent years, the use of alkaloids in Sophora sophora has made many breakthroughs in the field of medicine, and a large number of human medicines have been developed and produced. Picrine also has extremely broad prospects in the development of pollution-free biological pesticide products. The Chinese patent "Sophora Sophora Fungicide and Its Preparation Method" (CN1280775) discloses a recipe of Sophora Sophora fungicide. The main content of this invention is to crush the roots, stems, leaves and fruits of Sophora Sophora Sophora and extract them with a mixed organic solvent. ; Concentrate the extract to the same weight as the ground thing of Sophora Sophora t...
