Embodiment 1

[0035] 1. Experimental materials

[0036] Niacinamide was purchased from Solarbio as a finished product. Weigh 6.11g of nicotinamide into 50ml of distilled water to prepare a 1M mother solution, filter and sterilize and store at 4°C until use.

[0037] 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).

[0038] PDA medium formula: potato (peeled) 200g, glucose 20g, agar 15g, tap water 1000ml, natural PH

[0039] 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 application of nicotinamide for preparing fungicide used for controlling plant diseases caused by pathogenic fungi. Indoor toxicity measurement shows that nicotinamide has good inhibitory activity on plant pathogenic fungi. The nicotinamide serves as the fungicide, has the advantages of being efficient and low toxic, and meets the requirement of plant disease chemical control. At present, a great amount of fungicide are used, the fungicide resistance of pathogenic fungi is enhanced, traditional fungicide has severe pollution on the environment, is high in vestigital, and directly threats food safety of human. Nicotinamide is a small molecule compound which is degradable, free of pollution, environmentally friendly, poor in fungicide resistance and safe to non-target organisms, man and beast, can guarantee high quality of agricultural products, fruits and vegetables, meets the demand of sustainable development, and is wide in research and market application prospect.

Description

technical field [0001] The present invention relates to fungicidal active compounds, in particular to the use of nicotinamide in the preparation of fungicides for preventing and treating plant diseases caused by plant pathogenic bacteria. Background technique [0002] Plant pathogenic bacteria can cause great harm to the growth and development of plants, and cause huge losses to agricultural production every year. Plant disease is one of the natural disasters that seriously endanger agricultural production. According to the estimate of the Food and Agriculture Organization of the United Nations, the annual loss of grain and cotton production in the world is more than 10% due to disease. Plant diseases can not only reduce the yield of crops, but also seriously threaten the quality and safety of agricultural products and their international trade to a certain extent. [0003] The history of chemical control of plant diseases developed along with the occurrence of plant diseas...
