The application discloses a bactericidal composition and application thereof in prevention and treatment of corn dwarf mosaic, and belongs to the technical field of pesticides. An active ingredient of the bactericidal composition comprises carvacol and chlorobromoisocyanuric acid, and the weight ratio of the carvacol and the chlorobromoisocyanuric acid is 1:1-1:15. It is found that the effect of the carvacol and the chlorobromoisocyanuric acid mixed for preventing and treating corn dwarf mosaic is obviously higher than that of a single component, the synergistic effect of the two is obvious in the range of 1:1-1:15, and the best ratio is 1:5. The bactericidal composition can reduce the use dosage of the pesticide, improve the prevention and treatment effect, reduce the use cost, and improve the safety to crops and the environment.

The primer probe combination, kit and application for simultaneously detecting four corn pathogens belong to the technical field of molecular biology detection, and can solve the technical problems that the existing molecular biology detection methods for corn diseases cannot simultaneously detect multiple corn pathogens, or cannot simultaneously detect bacterial and viral pathogens of corn, and are complicated in operation and time-consuming. The primer probe combination for detecting corn inner state wilt fungus, corn bacterial wilt fungus, corn chlorotic mottle virus and corn dwarf mosaic virus, an integrated microfluidic chip kit containing the primer probe combination and a detection method are provided. The method for detecting pathogens in corn crops by using the primer probe combination and the kit has high sensitivity and accuracy, is simple, fast and time-saving in operation. The primer probe combination, kit and method can simultaneously detect the four pathogens, and play an important role in the on-site rapid detection of pathogens in corn planting.
