Embodiment 1

[0011] Example 1 The 20 small molecule phenolic compounds of chemical formulas (Z-1) to (Z-20) are all commercially available compounds.

[0012]

Embodiment 2

[0013] Embodiment 2: Indoor antibacterial activity assay and result

[0014] The phytopathogenic bacteria used in this experiment were strains stored at 4°C in the laboratory, and the medium used was potato agar dextrose medium (abbreviated as PDA). PDA medium formula: potato (peeled) 200g, glucose 20g, agar 15g, distilled water 1000mL, natural pH.

[0015] 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 four 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 aliquoting, sterilize at 121°C for 20 minutes, cool down and set aside.

[0016] 1) Experimental method

[0017] using the growth rate method.

[0018] 1. Cultivate 6 kinds of plant pathogenic bacteria on a PDA plate at 25°C for about 6 days before use.

[0019] 2. Heat and melt ...

Abstract

The invention relates to the field of medicinal chemistry, and discloses application of a phenolic compound in prevention and treatment of sclerotinia sclerotiorum, rhizoctonia solani, botrytis cinerea, cotton fusarium wilt, gibberella zeae and rice blast.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and discloses a new application of a class of small molecule phenolic compounds, specifically relating to its prevention and treatment of Sclerotinia sclerotiorum, Rhizoctonia solani, Botrytis cinerea, Cotton Fusarium wilt, Gibberella wheat and rice blast in the application. Background technique [0002] Plant disease is one of the natural disasters that seriously endanger agricultural production. According to the estimates of the Food and Agriculture Organization of the United Nations, the annual loss of grain and cotton production in the world due to diseases is more than 10%. Plant diseases can not only cause the reduction of crop yields and cause huge economic losses, but also seriously threaten the quality of agricultural products to a certain extent. security and international trade. At present, plant diseases caused by fungi are mainly controlled by chemicals. Although many commercial ...
