Embodiment 1

[0019] Remove impurities from Sophora flavescens, Tripterygium wilfordii, Toosendan, Toosendan bark, Aconitum chamaejasma, and Tangerine peel, and grind them into coarse powder. Take 30kg of sophora flavescens, 7kg of toosendan, 19kg of toosendan bark, 15kg of tripterygium twig, 24kg of tangerine peel, 4kg of chamaejamas, and put them into the extraction tank, add water 4 times the volume of the raw materials, soak for 1.5 hours, and heat to 40-50°C, hold for 20 minutes. Add 20 kg of cellulase with a mass percent concentration of 2% and an activity unit of 100 U, keep the temperature at 40° C. for 2.2 hours for enzymolysis, and then filter to obtain a traditional Chinese medicine solution. Adding 6.4kg of papain with a mass percentage concentration of 8% in the above-mentioned Chinese medicinal liquid is clarified, and the clarified liquid is left to stand and filtered at 55-60 degrees of low-temperature vacuum to concentrate to 1.25 grams of crude drug per milliliter of medic...

Embodiment 2

[0022] The preparation process is the same as in Example 1, wherein, 20kg of Sophora flavescens, 10kg of Toosendan, 16kg of Toosendan bark, 12kg of Tripterygium wilfordii, 20kg of Aconiti officinalis, 8kg of tangerine peel, 5kg of chamaejasma, the mass percentage concentration is 2%, and the activity unit is 100U 20kg of cellulase, 6.4kg of papain with a mass percent concentration of 8%. 15kg of traditional Chinese medicine extract containing matrine, 20kg of emulsifier 4209-X, 8kg of permeanthione, 0.1kg of antioxidant FF-04, and 56kg of deionized water.

Embodiment 3

[0024] The preparation process is the same as in Example 1, wherein, 25kg of Sophora flavescens, 8kg of Toosendan, 12kg of Toosendan bark, 10kg of Tripterygium wilfordii, 18kg of Aconiti officinalis, 7kg of dried tangerine peel, 6kg of chamaejasma, the mass percentage concentration is 2%, and the activity unit is 100U 20kg of cellulase, 6.4kg of papain with a mass percent concentration of 8%. 15kg of traditional Chinese medicine extract containing matrine, 18kg of emulsifier 4209-X, 6kg of osmotic agent genthinone, 0.1kg of antioxidant FF-04, 2kg of dimethyl sulfoxide, and 59kg of deionized water.

Abstract

The invention discloses botanical insecticide of soluble matrine used for killing cabbage caterpillar and a preparation method thereof, which aims at providing the botanical insecticide used for killing cabbage caterpillar and a preparation method thereof which adopts Chinese herbal medicine as raw material, has high matrine content, low toxin and low cost but high efficiency and is harmless to human and livestock.. The botanical insecticide comprises 15-20 portions of Chinese herbal medicine extract containing the matrine, 10-20 portions of emulsifier, 4-8 portions of penetrating agent, 0.1 portions of antioxidant and 55-60 portions of deionized water; the Chinese herbal medicine extract containing the matrine is extracted by mixing the following materials by weight portions: 20-30 portions of sophora flavescens ait, 7-10 portions of chinaberry fruit, 12-19 portions of chinaberry leaf, 10-15 portions of tripterygiumforrestii, 18-24 portions of raw aconitum, 4-6 portions of euphorbia and 6-8 portions of dried orangepeel. The insecticide comprises the matrine of super high content of about 2.0 percent and is directionally used for killing the plant louses through scientific compatibility of diversified Chinese herbal medicine components and has powerful penetrating performance that is in favor of absorption by plants, low cost per Mu (approximate to 667 square meter), low toxin, no RPP, no residue, no pollution and no drug resistance.

Description

technical field [0001] The invention belongs to the field of biological pesticides, and more specifically relates to a matrine aqueous plant insecticide specially used for killing cabbage caterpillars and a preparation method thereof. Background technique [0002] my country is the most populous country in the world, and it is also a big agricultural country. Developing rural economy, developing agriculture and related industries is one of the important policies of our country. For a long time, the extensive use of chemical pesticides in the production bases of agricultural products in the vast rural areas of our country has caused serious three pests, and the drug resistance produced by plant diseases and insect pests has become a recessive disease of crops and plants. The pollution of pesticide residues to the food chain and the environment has become increasingly prominent. The three pests problem not only restricts the development of agriculture, but also seriously end...
