Reagent for preventing and curing apple-tree valsa canker

Abstract

The invention discloses a reagent for preventing and curing apple-tree valsa canker. The reagent is prepared from, by weight, 6-8 parts of dandelion extract, 8-15 parts of radix aconiti kusnezoffii, 8-12 parts of perilla frutescens leaves, 28-35 parts of cortex magnoliae officinalis, 2-4 parts of tuba roots, 12-18 parts of wrinkled gianthyssop herbs and 25-30 parts of pine needles. Compared with the prior art, the reagent has the advantages that the raw materials are all plant materials, antibiotics are not contained, the reagent is applied directly in the injection mode or the fertilization mode, and medicine losses caused by poor medicine permeability can be avoided; the medicine acts inside a trunk, pathogenic bacteria of apple-tree valsa canker can be killed, and fungi diseases such as apple valsa canker are prevented.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a reagent for preventing and treating apple tree rot. Background technique [0002] Apple tree rot is a kind of branch disease. It is a traditional Chinese medicine disease of apple trees in northern my country. It usually causes tree vigor to weaken, branches to die, dead trees and even garden damage. The reason is mainly caused by the fungus Nigella nigricans, which live through the winter in the cortex of diseased plants and diseased residues in the field with mycelium, pycnidia and ascus. The germination continues, destroys plant tissue, and eventually leads to cortical tissue necrosis. At present, there are many methods to prevent and control rot disease, and most of them are concentrated in autumn and spring, but usually they cannot get a good preventive effect. In May-September of each year, rot bacteria will easily germinate, so it is necessary ...

Problems solved by technology

At present, there are many methods to prevent and control rot disease, and most of them are concentrated in autumn and spring, but usually they cannot get a good preventive effect. In May-September of each year, rot bacteria will easily germinate, so it is necessary to control rot bacteria during this period and the commonly used control method is to scrape off the bark and apply pesticides. This method can only be carried out after the disease spots are found. Usually it is too late, resulting in more serious rot. Even if it is cured, it will not It will be more serious in the next year. In addition, most of the chemical agents currently used to prevent and control apple tree rot in the market are poor in control effect, and the efficacy time is short, requiring multiple applications. On the other hand, the permeability of chemical agents Very poor, thereby prolonging the treatment time and as for effect again, therefore, need a kind of medicament that can fully bring into play medicinal effect and application method thereof, avoid the waste that causes because of apple tree rot
