Embodiment 1

[0037] 1. Experimental materials

[0038] Sodium valproate was purchased as a finished product from Sigma Corporation. Weigh 3.32g of sodium valproate in 20ml of distilled water to prepare a 1M mother liquor, filter and sterilize and store at 4°C until use.

[0039] The phytopathogenic bacteria used in this experiment were strains stored at 4°C in the laboratory, and the medium used was potato medium (PDA for short).

[0040] PDA medium formula: potato (peeled) 200g, glucose 20g, agar 15g, tap water 1000ml, natural pH.

[0041] 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 15-20g 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, cool down and set aside.

Abstract

The invention discloses an application of sodium valproate in preparation of a fungicide used for preventing and controlling plant diseases caused by phytopathogens. Indoor toxicity measurement proves that sodium valproate has good inhibitory activity on plant pathogenic fungi; sodium valproate can serve as a fungicide, has the advantages of high efficiency and low toxicity and can meet the plant disease chemical control requirement; at present, a large amount of fungicide is used, so that drug resistance of pathogenic bacteria is enhanced, and the traditional fungicide produces severe pollution to the environment, is high in residue amount and directly threats safety of human food; and sodium valproate is a degradable, pollution-free and environment-friendly micromolecular compound, has poor drug resistance, is safe to non-target organisms as well as people and livestock, can guarantee high quality of agricultural products, fruits and vegetables, can meet the sustainable development requirement and has a broad study and market application prospect.

Description

technical field [0001] The invention relates to fungicidal active compounds, in particular to the use of sodium valproate in the preparation of fungicides for preventing and treating plant diseases caused by plant pathogenic bacteria. Background technique [0002] With the global population increasing year by year, plant diseases, insect pests and weeds have aggravated the global disaster caused by food shortage. Currently, at least 800 million people in the world do not receive sufficient food supply. Among them, plant diseases have always been a serious threat in agricultural production, and a method for controlling plant diseases that meets food safety standards is urgently needed. Global climate change in the 21st century may bring serious epidemic diseases to food crops, which in turn poses a huge threat to future food security. Plant protection is an important means to ensure the sustainable development of agriculture. [0003] Currently, fungicides are still the fir...
