Mixture of bacterial medicine for controlling vegetable epidemic disease and preparation method

Abstract

A bacterium-chemial mixture for preventing and treating the diseases of vegetables is prepared through providing the biopreventing bacterium, fermenting culture, centrifugally depositing of fermented liquid, proportionally mixing it with powdered calcium carbonate and mixing it with bactericide.

Description

technical field [0001] The invention belongs to the field of chemical and biological soil treatment agents and preparation methods thereof, in particular to the field of a fungus-drug mixture capable of preventing and controlling vegetable blight and the preparation method thereof. Background technique [0002] Blight is a serious disease in vegetable production. Common blight mainly includes pepper blight, tomato late blight and cucumber blight. In my country, pepper blight is the most serious. In recent years, due to changes in varieties, cultivation systems, and fertilizer and water conditions, the disease has increased year by year, and the diseased area has expanded from south to north year by year. The death rate in severely diseased areas can reach more than 80%, and the yield loss is very significant. Capsicum blight can occur throughout the growth period of peppers, especially when peppers are budding and fruit-setting. Under favorable weather conditions, the dise...

Problems solved by technology

However, due to the fact that a single biocontrol factor is difficult to achieve the same control effect as the use of chemical fungicides under different environmental conditions; and the biocontrol factors are sensitive to fluctuations in the environmental conditions of the soil or the root circle of crops, under the ecological conditions of pathogenic bacteria in the field , the colonization ability of biological control factors is very different

At present, the research on biological control of vegetable diseases is mostly carried out in laboratories and greenhouses, and has not been used in large-scale production practice.
