Abstract

The invention discloses botanical bactericide of soluble matrine and a preparation method thereof, which aims at providing the botanical bactericide and a preparation method thereof which adopts Chinese herbal medicine as raw material and has high matrine content, low toxin and low cost but high efficiency and is harmless to human and livestock. The botanical bactericide comprises 17-25 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 48-56 portions of deionized water; the Chinese herbal medicine extract containing the matrine is extracted by mixing the following materials by weight portions: 30-35 portions of sophora flavescens ait, 20-35 portions of vietnamese sophora root, 10-15 portions of tea seed, 12-19 portions of common fibraurea stem, 7-10 portions of cubeb litsea, 6-9 portions of phellodendron, and 5-9 portions of magnolia officinalis. The bactericide comprises the matrine of super high content of about 2.6 percent and has special effect on killing pear scab, powerful penetrating performance that is in favor of absorption by plants, high efficiency, low toxin, 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 fungicide and a preparation method thereof. Background technique [0002] my country is the most populous country in the world and a big agricultural country. The development of rural economy, the development of agriculture and related industries is one of the important policies of our country. For a long time, in the vast rural agricultural production bases in my country, the three pests caused by the extensive use of chemical pesticides and the drug resistance caused by diseases and insect pests have become hidden diseases of crops and plants. The pollution of pesticide residues to the food chain and the environment has become increasingly prominent. The problem of three pests not only restricts the development of agriculture, but also seriously endangers human life and health. The harm it causes is immeasurable. The harm of long-t...
