Plant source synergistic compound bactericide and application thereof

Abstract

The invention discloses a plant source synergistic compound bactericide and an application thereof. The compound bactericide is prepared by the following steps: by taking berberine and emodin monomethyl ether as main components, adding the aids, and compounding to obtain the product. The dosage forms of the preparation refer to environment-friendly missible oil, microemulsion, aqueous solution or dissoluble liquid. The preparation comprises 0.1-20 percent of berberine, 0.1-20 percent of emodin monomethyl ether and the balance of aids. The compound bactericide does not contain any chemical pesticide component, is easy to degrade in the environment, does not have environmental pollution and residual toxins and is safe to the people, livestock and environment, and drug resistance is difficultly generated by pathogenic bacteria; the powdery mildew, gray mold, anthracnose, downy mildew, phytophthora root rot, brown rot, tea leaf blight and other agricultural diseases on melons, fruits, vegetables and tea trees can be controlled, and the compound bactericide has extremely high application and popularization values on melons, fruits, vegetables, tea, medicinal materials and other main agricultural and sideline products exported for earning foreign exchange and is an ideal novel pollution-free bactericide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a fungicide with two plant-derived substances, berberine and emodin methyl ether, as active components and its application. Agricultural diseases such as powdery mildew, gray mold, anthracnose, downy mildew, phytophthora, brown rot, moire leaf blight, etc. Background technique [0002] Powdery mildew, gray mold, anthracnose, downy mildew, phytophthora, brown rot, moire leaf blight, etc. are the main diseases on melons, fruits, vegetables, and tea leaves. They have a wide range of damage and are difficult to control. Big. At present, the medicaments used to prevent and control these diseases are mainly chemical fungicides. However, the long-term use of a large number of chemical drugs has led to the emergence of problems such as drug resistance, environmental pollution, and harm to human health; The use of many chemical pesticides has had to be restricted.
