Description
Technical field
The present invention relates to disinfectant use in agriculture category, specifically, it relates to be botanical fungicide and its preparation method of the control cucumber downy mildew that a kind of food-processing by product is made.
Background technology
Cucumber downy mildew is the fungal disease that Folium Cucumidis sativi portion the most often occurs, it is cause by Mastigomycotina Pseudoperonospora fungal attack, pathogenic bacteria is obligate parasite, and the specialization selectivity of host is very strong, its sporocyst can be propagated with wind and rain, cucumber beetle, agriculture utensil etc., is a kind of main air infection diseases. Seedling stage, strain all can be injured, main harm blade. The seedling phase falls ill, and irregular chlorisis tawny spot occurs in cotyledon front, and time moist, the scab back side produces the mould shape thing of beige, and time serious, cotyledon turns yellow withered. Strain is fallen ill, and how from forward position, greenhouse, in morbidity strain before this, water stain shape, light green speckle occurs in lower blade reverse side, and front does not show, and rear scab expands gradually, front exposed, and scab shows tawny, limits by vein, and scab is polygon. In humid conditions, there is puce or the sparse mould layer of beige in the scab back side, and time serious, scab joins together, and blade dries up.
At present, the main sterilant used of control of cucumber cream mold is had that white corruption is clean, the mould spirit of the white evil of first, second aluminium manganese zinc, Du Pont gram dew, zinc 1,2-propylene bisdithiocarbamate, the contour poison of zineb and high residue chemical pesticide, but owing to oidium very easily develops immunity to drugs, and resistance level rising is fast. Simultaneously owing to using chemical pesticide in a large number for a long time so that the disadvantageous effect such as high residue and contaminate environment is day by day outstanding. Along with the reinforcement of environmental legislation and Public environmental attitude, the public more and more requires that agriculture production contains less or not containing the agricultural-food of chemical residue, many pesticide species are disabled.
Therefore, for the problem of the oidium harm existed in current cucumber production, the present invention utilizes zingiberaceous plant to discard the corresponding biological prevention and control agent of part Study and Development, control cucumber downy mildew that not only can be safe, slow down the generation of target resistance, meanwhile, resource discarded after also using food-processing, realization is turned waste into wealth, and is conducive to recycling economy and Sustainable development.
Summary of the invention
For defect of the prior art, it is an object of the invention to provide that a kind of production cost is low, a kind of botanical fungicide for preventing and treating cucumber downy mildew of environmental friendliness, high comprehensive performance and its preparation method.
According to an aspect of the present invention, it is provided that a kind of botanical fungicide preventing and treating cucumber downy mildew, described sterilant comprises food-processing by product, solubilizing agent and water. The weight percentage of sterilant gross weight shared by them is respectively: food-processing by product 10��50%, solubilizing agent 5��20%, all the other are water. Described food-processing by product refers to one or more in corn distilled water, ginger distilled water, turmeric distilled water, wheat distilled water, grape distilled water, camellia distilled water.
Preferably, described food-processing by product, can be following one or more: corn distilled water, ginger distilled water, turmeric distilled water, wheat distilled water, grape distilled water, camellia distilled water, the weight percentage that each component that wherein said food-processing by product comprises accounts for produced sterilant is respectively: corn distilled water 10��40%, ginger distilled water 10��30%, turmeric distilled water 20��50%, wheat distilled water 10��35%, grape distilled water 10��35%, camellia distilled water 10��35%.
Preferably, described solubilizing agent, refers to and can reduce surface tension, increases wettability, the one of the sterilant auxiliary agent (tea saponin, organosilicone surfactants, Tweens tensio-active agent etc.) of tackiness and perviousness.
According to another aspect of the present invention, the preparation method of the botanical fungicide of a kind of above-mentioned control cucumber downy mildew is provided, it is specially: by one or more mixtures of the food-processing by products such as corn distilled water, ginger distilled water, turmeric distilled water, wheat distilled water, grape distilled water, camellia distilled water, add solubilizing agent, conveniently technique, makes the botanical fungicide of the control cucumber downy mildew of the present invention.
