Abstract

The invention provides an application of a graphene aqueous dispersion in prevention of bacterial wilt of crops. The mass fraction of graphene in the graphene aqueous dispersion is 0.001-0.1%. The graphene aqueous dispersion provided by the invention can effectively prevent bacterial wilt of crops, does not pollute soil, does not influence crop growth, and is greener and more environment-friendly.

Description

technical field [0001] The invention relates to the application field of graphene, in particular to the use of a graphene aqueous dispersion in preventing bacterial wilt of crops. Background technique [0002] Bacteria wilt, pathogen (scientific name of pathogenic bacteria): Ralstonia solanacearum, bacteria. Initially, the aboveground part of the plant without any abnormal phenomenon suddenly lost its vitality during the day, and the entire aboveground part withered. Cloudy days and morning and evening recover, just like a healthy plant, however, it will wither soon after, showing symptoms of withering, and this process is progressing very rapidly. It is a worldwide disease widely distributed in the tropics, subtropics and some temperate regions, and is the main reason for the production reduction of many crops. [0003] At present, there is no good method for the prevention of plant bacterial wilt in the industry. Generally, bactericidal pesticides are used to irrigate or...
