Embodiment 1

[0035] 1. Experimental materials

[0036] Butyric acid is a finished product purchased from Fluka. Weigh 4.47g of butyl benzene hydroxy acid in 20ml of dimethyl sulfoxide to make a 1M mother liquor, filter and sterilize and store at 4°C until use.

[0037] The plant pathogens used in this experiment are strains stored at 4°C in the laboratory, and the medium used is potato medium (PDA for short).

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

[0039] Preparation method: Wash and peel the potatoes, weigh 200g and cut into small pieces, add water to boil (boil for 20-30 minutes, can be pierced by a glass rod), filter in a beaker with eight layers of gauze, add according to the needs of the experiment 15-20g agar, add 20g glucose, stir evenly, fully dissolve and cool to make up water to 1000ml, sterilize at 121°C for 20 minutes after aliquoting, and cool for use.

[0040] 2. Experimental method

[0041] Use the growth rate method.

Abstract

The invention discloses the application of bufexamac in preparation of a bactericide used for controlling a plant disease caused by phytopathogen. It is proved that bufexamac has the good inhibitory activity on plant pathogenic fungi through indoor toxicity measurement. The bufexamac used as the bactericide has the advantages of high efficiency and low toxicity, and meets the requirement for plant disease chemical control. At present, a large number of bactericides are used, phytopathogen drug resistance is enhanced, and traditional bactericides are high in environmental pollution and residue and directly threaten the food safety of human beings. However, the bufexamac is a small molecule compound which is degradable, free of pollution, environmentally friendly, poor in drug resistance, safe for non-target organisms, people and livestock, capable of ensuring high quality of agricultural products, fruits and vegetables and meeting the requirement for sustainable development, and wide in search and market application prospect.

Description

Technical field [0001] The present invention relates to bactericidal active compounds, in particular to the use of bufenac in the preparation of bactericides for preventing and treating plant diseases caused by plant pathogenic bacteria. Background technique [0002] Agriculture is the foundation of human society and economic development, and sustainable agriculture is the trend of world agricultural development. Since the 20th century, with the advancement of science and technology and the improvement of social productivity, mankind has created unprecedented wealth. At the same time, problems such as rapid population growth, resource shortage, environmental pollution, ecological damage and frequent natural disasters have become increasingly prominent, which have seriously hindered agriculture. As a result, agricultural production is under unprecedented pressure. Research and practice at home and abroad show that plant diseases are a major factor restricting the sustainable deve...
