Abstract

The invention discloses a sterilization composition, a sterilization pesticide and the application of the sterilization composition or the sterilization pesticide. The sterilization composition consists of kasugamycin and cuppric nonyl phenolsulfonate, and the weight ratio of the kasugamycin to the cuppric nonyl phenolsulfonate is 1:40 to 40:1, preferably 1:20 to 20:1. The composition serving as an active ingredient and acceptable auxiliary components in the pesticide form the sterilization pesticide in form of microemulsion, wettable powder and the like. When the sterilization composition or the sterilization pesticide is applied to the prevention and control of cucumber bacterial angular leaf spots, rice bacterial leaf blight and tobacco wildfire, a remarkable synergistic effect can be achieved, the application amount of each single dosage can be effectively reduced, a lasting period can be prolonged, and the generation of pesticide resistance of pathogenic microorganisms can be retarded; and the sterilization composition, the sterilization pesticide and the application have remarkable popularization value.

Description

technical field [0001] The invention relates to an agricultural fungicidal composition, in particular to a fungicidal composition composed of kasugamycin and nonyl copper, as well as the corresponding fungicidal pesticide and its application in preventing and treating crop diseases. Background technique [0002] Cucumber bacterial angular spot is one of the important diseases on cucumber. It often occurs mixed with cucumber downy mildew in the field, and the lesions are relatively close, and sometimes it is easy to confuse, but cucumber downy mildew produces several polygonal water-soaked lesions on the back of the leaves in the early stage of the disease, while bacterial angular spot is on the back of the leaves Acicular water-soaked lesions are produced, and dozens of lesions often occur at the same time. The commonly used preventive drug is streptomycin sulfate, but due to long-term use, the pathogenic bacteria have developed serious drug resistance, resulting in shorten...
