Problems solved by technology
[0007] 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 2-cyano-3-amino-3-ethyl phenylacrylate and metalaxyl-M as well as applications thereof. The sterilization composition containing 2-cyano-3-amino-3-ethyl phenylacrylate and metalaxyl-M employ 2-cyano-3-amino-3-ethyl phenylacrylate and metalaxyl-M as main active components, and the weight ratio between 2-cyano-3-amino-3-ethyl phenylacrylate and metalaxyl-M is 1-70:1-50. The invention also discloses an application of the sterilization composition to medicines for controlling fungal diseases of resistant plants, the composition can be applied to control of diseases of cereals, fruit trees, and vegetables with high synergistic interaction effects, and pesticide resistance of pathogens is overcome and delayed; the composition has the advantages of fast sterilization speed and long persistent period, reduced application cost, and control effects which are obviously better than the effects of usage of single dose. The composition is used for controlling fungal diseases on crops, and especially can be used for controlling wheat scab, rice bakanae disease, tomato wilt, downy mildew, and phytophthora blight, and other fungal diseases, and the effects of the composition are better than effects of usage of single dose.
Description
technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition containing cyclostrobin and metalaxyl and its application. Background technique [0002] Cyclostrobin, appearance is white powder, molecular formula: C 12 h 12 N 2 o 2 , chemical name: ethyl 2-cyano-3-amino-3-phenylacrylate. [0003] Cyanostrobin is a 2-cyanoacrylate fungicide, which is a new type of fungicide with a unique mode of action. It is effective against diseases caused by Fusarium, especially for head blight caused by Fusarium and Fusarium moniliforme Rice bakanae disease and tomato wilt caused by Fusarium oxysporum have good control effects. Cyclostrobin is absorbed through the root, has upward transport on the leaves, and has poor transport towards the lower part of the leaves and between the leaves. [0004] Metalaxyl-M, molecular formula: C 15 h 21 NO 4 . Chemical name: N-(2,6-xylyl)-N-(methoxyacetyl)-D-alanine me...
