Abstract

The invention discloses a biopesticide for preventing and treating bacterial diseases of potatoes and a preparation method of the biopesticide. The biopesticide is prepared from the following raw materials: compound microorganisms, white sugar, cooked fish meat, mashed garlic, chili powder and clear water. The preparation process of the biopesticide comprises the following steps: mixing each single bacterial liquid according to a preset weight ratio to obtain a compound microorganism; mixing compound microorganisms, white sugar, cooked fish meat and clear water according to a preset weight ratio to obtain a mixed material; carrying out facultative fermentation on the mixed material at the temperature of 25-35 DEG C, and ending the fermentation when the pH value of the fermentation liquid is less than or equal to 3.8; adding mashed garlic and chilli powder into the fermented liquid according to a preset weight ratio, then placing in a sealed manner, and finally filtering to obtain filtrate as the biopesticide. The biopesticide disclosed by the invention is used for planting potatoes, and can prevent and treat bacterial diseases in the potato production process, promote the growth of the potatoes and improve the yield of the potatoes.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a biological pesticide for preventing and treating bacterial diseases of potatoes and a preparation method thereof. Background technique [0002] With the continuous deepening of understanding of the nutritional value of potatoes, people's consumption demand for potatoes is increasing. Therefore, improving the yield and quality of potatoes is of great significance to my country's food security and sustainable development of society. [0003] In addition, potatoes are susceptible to bacterial diseases (such as ring rot, bacterial wilt, black shank, soft rot, etc.) Healthy development of potato farming. [0004] Therefore, developing a biopesticide containing biocontrol bacteria and applying it to potato cultivation is of great significance for promoting potato production. Contents of the invention [0005] The technical problem to be solved by the present in...
