Abstract

The invention relates to an application of psoralen in preventing and treating plant bacterial diseases, and belongs to the technical field of botanical bactericides. The compound can effectively inhibit the growth of xanthomonas, such as Xanthomonas oryzae pv.oryzae, Xanthomonas oryzae pv.oryzicola, Xanthomonas campestris pv.campestris and the like, and plant source bactericide processed by the compound as an active ingredient can be used for preventing and treating plant bacterial diseases caused by xanthomonas. The compound and other bactericide can be alternately used to delay the generation of drug resistance.

Description

technical field [0001] The invention belongs to the technical field of botanical fungicides, and in particular relates to the application of psoralen in preventing and treating plant bacterial diseases. Background technique [0002] Bacterial plant diseases are an important class of plant diseases, once the disease occurs, it will cause huge losses to agricultural production. At present, there is a serious shortage of plant bacterial disease control agents, and common control agents have resistance problems due to long-term use, so it is urgent to develop new control agents for alternate use. [0003] Psoralen is derived from the leguminous plant psoralen ( Psoralea corylifolia L.) A furanocoumarin compound in the fruit, which has rich biological activities. Among the literature and patents that can be retrieved at present, "Use of psoralen as an agricultural fungicide or insecticide" (patent application number: 201110050088.4) discloses the use of psoralen in the prevent...
