Abstract
The invention relates to a method for preventing and treating dendrobe sooty mould. A microemulsion which is prepared by taking a plant source extraction liquid as an active ingredient is used for preventing and treating dendrobe sooty mould. The microemulsion is prepared from the following raw materials in percentage by weight: 15-20% of the plant source extraction liquid, 10-20% of normal propanol, 10-15% of styrylphenol polyoxyethylene ether, 5-10% of tween-80 and the balance of water, totally 100%. The assistant and guide relationship among the plant materials is comprehensively considered, so that the method can be used for obviously improving the preventing and treating effect on dendrobe sooty mould.
Description
Technical field
The present invention relates to the pest control of the stem of noble dendrobium, be specifically related to a kind of method of preventing and treating stem of noble dendrobium sooty mould.
Background technology
Compare with traditional chemical agricultural chemicals, botanical pesticide have raw material to be easy to get, action site is many, pest not easily develops immunity to drugs, easily degraded, low-residual, to the natural enemy insect harm advantage such as less and environmentally safe.High active substance is filtered out from natural products, be templated synthesis new chemical agricultural chemicals with it, or be directly developed to efficient, low toxicity, low-residual, natural source pesticidal preparations with harmonious environment, having become important and one of the effective approach of of New pesticides discovery, is the developing direction of pesticide in future.China soil is vast, and plant resources enriches, and the condition of development botanical fungicide is richly endowed by nature, and prospect is very wide.According to statistics, about there is plant more than 50 ten thousand kinds in the whole world, nearly more than 30 ten thousand kinds of higher plant, existing higher plant 470 section of China, and more than 3700 belong to, and about 30,000 kinds, occupy third place in the world." Chinese poisonous plant " lists China poisonous plant kind more than 1300 in, and wherein great majority have bactericidal activity, and numerous species is utilized by as botanical pesticide.
But for the medicine based on herbs in currently available technology, mostly arbitrarily combine according to the effect of each composition, do not consider the relation of the monarch between various composition, not only cause the effect after combining not increase, the effect after combination can be affected on the contrary.
Medicine based on herbs is not adopted to be specifically designed to the report of control stem of noble dendrobium sooty mould in prior art yet.
Summary of the invention
The present invention is directed to some problems in currently available technology, considered the monarch relation between vegetable material, the prevention and controls of the stem of noble dendrobium sooty mould of drug effect after providing a kind of combination, can be significantly improved.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the prevention and controls providing a kind of stem of noble dendrobium sooty mould, the microemulsion using plant resource extract as active fraction preparation is adopted to prevent and treat, wherein, described microemulsion is prepared by mass percentage by following raw material: plant resource extract: 15-20%, normal propyl alcohol: 10-20%, styrylphenol polyoxyethylene ether: 10-15%, Tween-80 5-10%, surplus is water, and the mass percent summation of raw material is 100%; Described plant resource extract is prepared by following methods: get celastrus orbiculatus 13-18kg, purple perilla 20-25kg, Patrinia scaniosaefolia 3-5kg, blackberry lily 0.5-1kg, black nightshade 0.1-0.3kg respectively, mixing after mincing with the meal that plant tissue cracker is crushed to 1mm ~ 3mm, the meal of gained is minced with conventional solvent method lixiviate, Extracting temperature is 80 ~ 90 DEG C, extraction time is obtain extract in 15 ~ 20 hours, extract to being equivalent to 1kg dry powder/kg concentrate, namely obtains plant resource extract through Vacuum Concentration.
Described microemulsion is prepared by mass percentage by following raw material: plant resource extract 18%, normal propyl alcohol 15%, styrylphenol polyoxyethylene ether 13%, Tween-20 7%, and surplus is water, and the mass percent summation of raw material is 100%.
Described solvent is any one or a few in ethyl acetate, chloroform, benzinum.
The consisting of of plant in described plant extraction liquid: celastrus orbiculatus 15kg, purple perilla 23kg, Patrinia scaniosaefolia 4kg, black nightshade 0.2kg, blackberry lily 0.8kg.
The plant compatibility of the application is the interaction of the state of an illness according to stem of noble dendrobium sooty mould and plant, select celastrus orbiculatus, purple perilla, Patrinia scaniosaefolia, black nightshade, blackberry lily with the use of method, wherein celastrus orbiculatus, purple perilla is monarch, Patrinia scaniosaefolia is minister, blackberry lily is assistant, black nightshade is for making, object is the state of an illness adapting to complicated stem of noble dendrobium sooty mould, prophylactic agent is poisoning, this formula is on the basis that differential diagnosis in tcm opinion is controlled, according to the performance of Four Plants sterilization and correlation compatibility, therefore, the overall compatibility of the application, notice that righting turns round and look at stomach, distinguish celastrus orbiculatus, purple perilla is main, Patrinia scaniosaefolia, blackberry lily, black nightshade is secondary, though emphasize particularly on different fields between main points, but connect each other, a unified entirety, only have during embody rule and organically combine four, just can reach the promising result of medicine Synergistic biocidal.
