Abstract

The invention discloses application of a compound paeonol as an agricultural bactericide. The compound is used as a bactericide for preventing and treating agricultural fungal diseases, and can effectively prevent and treat crop diseases such as fusarium wilt, gray mold, gibberellic disease, gummy stem blight and the like. The agricultural bactericide prepared from paeonol as an active component has the characteristics of good prevention and treatment effect, broad spectrum, low toxicity, no residue, no pollution and no public nuisance, and is particularly beneficial to environmental protection.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to the use of a compound paeonol as an active ingredient in the preparation of an agricultural fungicide. Background technique [0002] Crop diseases are not as easy to be detected in time as pests and weeds, so they often cause neglect and difficulty in prevention and control, so their harm is even more serious. According to reports, there are as many as 10,000 plant diseases caused by pathogenic fungi in the world, and the losses caused account for 10% to 30% of the total annual crop losses. If plant diseases caused by viruses, bacteria and nematodes are included, the losses will be even more considerable. [0003] In order to meet people's increasing demand for food and other living materials, chemicals have to be used to protect crops from harmful organisms, among which fungicides play an important role. Natural products with agricultural bactericidal activity ...
