Purely natural soil insectofungicide

Abstract

The invention discloses a purely natural soil insectofungicide. The insectofungicide is prepared from the following raw materials in parts by weight: 10-14 parts of fructus ulmi, 5-10 parts of rumex japonicus, 5-10 parts of fructus quisqualis, 6-12 parts of cortex meliae, 10-14 parts of garlic, 5-10 parts of Chinese prickly ash, 5-8 parts of radix stemonae and 10-15 parts of semen arecae. The environment-friendly soil insecticide disclosed by the invention is a pollution-free and broad-spectrum insecticide dedicated for soil, which is obtained in the way that the raw materials are scientifically prepared and subjected to supercritical carbon dioxide extraction by adopting the biotechnology of modern science and technology; compared with water decoction in the prior art, the adopted technology has the following advantages: various effective components are easier to extract, the use ratio of the traditional Chinese medicine is high, the insecticidal and antibacterial effects are better, the drug property is mild, pests, bacteria and spawns in soil can be effectively killed, environmental pollution is avoided, and the insectofungicide is basically free of toxic and side effects on human and livestock, long in effective duration, low in dosage and high in safety.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pure natural soil insecticide and fungicide. Background technique [0002] my country is one of the earliest countries to use pesticides and has a very long history. The use of organochlorine pesticides in the late 1980s had a great impact on the soil. With the vigorous promotion of pollution-free agricultural products in my country , high-efficiency, low-toxicity, and low-residue pesticides are gradually being respected by consumers, and the widely used pesticides are still chemical preparations after all. Although they have good insecticidal effects, such low-residue chemicals are still harmful to the environment. It will cause pollution, have toxic and side effects on humans and animals, and is not conducive to long-term development. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a pure natural soil insecticide an...
