Embodiment 1

[0028] 1. Experimental materials

[0029] Sodium butyrate was a finished product purchased from Sigma. Weigh 5.50 g of sodium butyrate in 50 ml of distilled water to prepare a 1M mother liquor, filter and sterilize and store at 4°C until use.

[0030] The plant pathogens used in this experiment are common pathogens (pathogens can be isolated from diseased plants), and are stored at 4°C in the laboratory.

[0031] The culture medium that adopts is potato medium (being called for short PDA), and PDA medium formula: potato (peeled) 200g, glucose 20g, agar 15g, tap water 1000ml, natural pH. Preparation method: wash and peel the potatoes, weigh 200g, cut into small pieces, add water and boil until rotten (boil for 20-30 minutes, it can be pierced by a glass rod), filter it into a beaker with eight layers of gauze, add 15g of agar, Add 20g of glucose, stir evenly, fully dissolve and then cool down to make up water to 1000ml, after subpackaging, sterilize at 121°C for 20 minutes, c...

Abstract

The invention discloses the use of sodium butyrate in preparing a fungicide for preventing and treating plant diseases caused by plant pathogenic bacteria. As a novel, green and environmentally friendly small molecular compound, sodium butyrate has less pollution and can be Degradation, and has the advantages of low toxicity, poor drug resistance, safety to non-target organisms and humans and animals, etc. The present invention proves through experiments that sodium butyrate can be used to prevent and control plant pathogenic fungi such as Deuteromycota fungi and Ascomycota fungi, It can be used to inhibit a variety of plant pathogenic fungi, has a wide range of bacteriostasis, and has a high bactericidal rate and low toxicity, which can ensure the high quality of agricultural products and fruits and vegetables, and meet the requirements of sustainable development. Its research and application prospects are broad.

Description

technical field [0001] The invention belongs to the technical field of biological control, and relates to bactericidal active compounds, in particular to the use of sodium butyrate in the preparation of fungicides for preventing and treating plant diseases caused by plant pathogenic bacteria. Background technique [0002] The survival of human beings is inseparable from the relationship between animals and plants. The healthy growth and normal development of plants can provide humans with more and better grain, oil, food, fruit and vegetable products and other various agricultural and sideline products. However, plant pathogenic bacteria can cause various diseases of plants, directly affect the yield and quality of products, and thus have a significant impact on human agricultural production and national economy. At present, chemical control is widely used in agricultural production due to its high efficiency and good selectivity. However, due to the improper use or even abu...
