Immunity detection reagent kit for rice black-streaked dwarf fijivirus in single-head small brown rice planthopper

The invention discloses an immunodetection kit specially used for rice black-streaked dwarf virus in single planthopper and a using method thereof. Specific polyclonal antibodies of the rice black-streaked dwarf virus (RBSDV) are utilized to build a dot immuno-binding assay (DIBA) detecting method which is used for building the detection kit for rice black-streaked dwarf virus, main reagents of the kit are working solution or concentrated solution, and the kit has the characteristics of convenient use, simple operation, and the like. And simultaneously, the use of the rice black-streaked dwarf virus detection kit can be a standard program or a reduced program, which can greatly broaden the using ranges and applicable persons of the kit and facilitate the population and application of the technique to establishment units, and further, the kit is applied in the fields of plant disease prognosis and prediction and the formulation of prevention and curing strategies, and the like. In addition, the kit can be used for measuring the inoculation strength in varietal resistance seed selection of rice black-streaked dwarf virus, and the like.
