Problems solved by technology
[0008] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge

The invention discloses a sterilization composition containing Bixafen and zineb and application thereof. The sterilization composition takes the Bixafen and the zineb as main effective ingredients, wherein the mass ratio of the Bixafen to the zineb is (1-70):(1-50). The sterilization composition can be used for preventing and curing cereal, fruit tree and vegetable diseases, has a higher synergistic interaction action, overcomes and delays the drug resistance of bacteria, has the advantages of high sterilization speed and long lasting period and lowers application cost, and the prevention and cure effect of the sterilization composition is obviously superior to the prevention and cure effect brought when the Bixafen or the zineb is singly used. The sterilization composition can be used for preventing and curing fungi on crops, and can be especially used for preventing and curing fungal diseases including wheat powdery mildew, grape downy mildew, stripe rust of wheat and barley, corn northern leaf blight, tea red scab, tobacco seedling dry rot and the like, and the effect of the sterilization composition is obviously superior to the effect brought when the Bixafen or the zineb is singly used.
Description
Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with bixafen and zinc zineb as main active ingredients and its application. Background technique [0002] Bixafen (Bixafen), chemical formula: C 18 h 12 C l2 f 3 N 3 O, chemical name: N-(3′,4′-dichloro-5-fluorodiphenyl-2-yl)-3-(difluoromethyl)-1-methylpyrazole-4-carboxamide. Structural formula: [0003] [0004] Bixafen is a pyrazole fungicide, a new type of systemic fungicide with broad-spectrum, protective and therapeutic activities. [0005] Zinc (Zineb), molecular formula: C 4 h 6 N 2 S 4 Zn, chemical name: zinc ethylene bisdithiocarbamate. Structural formula: [0006] [0007] Zinc is a broad-spectrum, protective fungicide. It can be used to control a variety of diseases of rice, wheat, vegetables, grapes, fruit trees, tobacco and other crops, such as wheat rust, corn leaf spot, tea spot, tobacco blight, anthracn...
