Abstract
The invention provides a botanical fungicide for controlling cucumber downy mildew and a preparation method thereof. Metered by the total weight, the fungicide comprises the following materials in percentage by weight: 10-50 percent of food processing byproduct, 5-20 percent of solubilizer and the balance being water, wherein the food processing byproduct refers to one or several in corn distilled water, ginger distilled water, turmeric distilled water, wheat distilled water, grape distilled water and camellia distilled water. The fungicide is mainly applied to plants by a spraying method, is made from the readily available raw materials, is simple in processing and low in equipment requirement and remarkably contributes to industrial production; a recycled organic solvent can be repeatedly utilized, resources are reutilized, secondary pollution is avoided, and thus sustainable development of agriculture is promoted.
Description
Technical field
The present invention relates to disinfectant use in agriculture category, particularly, what relate to is botanical fungicide of the control cucumber downy mildew made of a kind of food processing accessory substance and preparation method thereof.
Background technology
Cucumber downy mildew is the fungal disease that cucumber leaf portion the most often occurs, to be caused by the infringement of Mastigomycotina Pseudoperonospora fungi, pathogen is obligatory parasitic bacteria, and the specialization selectivity to host is very strong, its sporangium can be propagated with wind and rain, cucumber beetle, agriculture utensil etc., is a kind of main aeroborne disease.Seedling stage, strain all can be injured, main harm blade.Seedling Stage morbidity, the irregular chlorisis yellowish-brown spot of the positive generation of cotyledon, when moist, the scab back side produces taupe mustiness thing, and when serious, cotyledons turn yellow is withered.Strain morbidity, how, from forward position, greenhouse, there is water stain shape, light green fleck in morbidity strain before this middle and lower part blade reverse side, and front is aobvious, and rear scab expands gradually, front exposed, scab shows yellowish-brown, limited by vein, and scab is polygonal.Under wet condition, there is puce or the sparse mould layer of taupe in the scab back side, and when serious, scab joins together, and blade is withered.
At present, the bactericide that the control of cucumber cream mold is mainly used has that white rot is clean, the chemical pesticide of the mould spirit of the white evil of first, second aluminium MnZn, Du Bangkelu, Propineb, the contour poison of zineb and high residue, but because downy mildew very easily develops immunity to drugs, and resistance level rises fast.Due to long-term a large amount of chemical pesticides that use, the adverse effects such as high residue and contaminated environment are become increasingly conspicuous simultaneously.Along with the reinforcement of environmental legislation and Public environmental attitude, the public more and more requires agricultural production to contain less or not containing the agricultural product of chemical residue, many pesticide species are disabled.
Therefore, problem for the downy mildew harm existing in current cucumber production, the present invention utilizes the discarded part of zingiberaceous plant to develop and develop corresponding biological prevention and control agent, control cucumber downy mildew that not only can be safe, slow down the drug-fast generation of target, meanwhile, also utilized resource discarded after food processing, realization is turned waste into wealth, and is conducive to recycling economy and sustainable development.
