Have now found that the use that is mixed of SYP-Zo48 and triazole bactericidal agent has very obvious synergistic effect, have significance to improve, and can enlarge fungicidal spectrum, delay the drug-fast generation of pathogen the control efficiency of corps diseases.The disinfecting composition that the present invention proposes contains SYP-Zo48 and any one or two or more triazole type bactericidal active constituent.Because two class medicaments possess different structure types and different mechanism of action, the two composite can the pathogen pesticide resistance produces and development delaying to a greater extent, thereby reached main purpose of the present invention.
In the bactericidal composition of the present invention, the ratio of weight and number of SYP-Zo48 and two kinds of active components of triazole bactericidal agent is 1: 100 to 100: 1.Better suited ratio is 1: 20 to 20: 1.
Active component is 0.5% to 95% of a gross weight in the bactericidal composition of the present invention.The amount that contains active component in the bactericidal composition of the present invention depends on the amount of application when every kind of component is used separately, also depends on the ratio of a kind of component and another kind of component and the degree of synergistic effect.
Contain at least two kinds of carriers in the bactericidal composition of the present invention, carrier can be solid or liquid, and the carrier that is generally used for preparing bactericidal composition all can use.At least a carrier is a surfactant in the composition of the present invention, for example can be emulsifier, dispersant or wetting agent etc.Surfactant all has commercially available, and its selection is known in those skilled in the art, for example, and lauryl sodium sulfate, Teepol, neopelex, polyoxyethylene fatty acid fat, polyoxyethylene aliphatic alcohol ether or polyoxyethylene fatty amine etc.
The present composition can be mixed with missible oil, suspending agent, (water) emulsion, wetting powder, (aqueous dispersion) granule etc., and these preparations can be prepared by method in common.
The composition that the present invention describes can be the finished product preparation form to be provided, and promptly each material mixes in the composition; But the composition of composition also can provide with independent preparation, directly mixes in bucket (jar) before using.Concentrate of the present invention mixes the concentration that obtains required active substance usually with water.
Composition of the present invention can be used for preventing and treating the disease that is caused various plants by sac fungi, basidiomycetes and imperfect fungus, as cereal, wheat, paddy rice, grape, strawberry, cucumber, custard squash, capsicum, pimento, eggplant, tomato, Kidney bean, cowpea, leek, lettuce, Chinese cabbage, sunflower, lichee, tobacco, rubber and some flowers, traditional Chinese medicine, lawn etc.The place of using of bactericidal composition of the present invention is farmland, orchard or warehouse etc.
Composition of the present invention also can with other compound with weeding, desinsection or bactericidal property particularly protective fungicide mix use, can also mix use with nematocide, protective agent, growth regulator, nutrient for plants or soil conditioner.
The present invention comprises that also a kind of scene kills the method for fungi, before or after crop is susceptible, uses composition of the present invention to the place of crop and plant growth or storage.Can use by common method, as cast, injection, spraying.Amount of application of the present invention is with weather condition or crop state variation.The duration of protective effect is usually relevant with the content of individualized compound in the composition, also relevant with extraneous factor, weather for example, but by using suitable formulation can slow down climatic influences.
Composition of the present invention has three advantages: the one, and composition shows fabulous synergistic effect in certain ratio range, mixed composition has obviously improved bactericidal effect than its single agent, thereby reduced using dosage, when reducing peasant's drug cost, reduced influence degree.The 2nd, enlarged fungicidal spectrum, a kind of medicament can be prevented and treated the various crop disease simultaneously, and a kind of dispenser means extremely easily and effectively are provided.Has the well double effect of controlling for simultaneous disease on the various plants, as graw mold of tomato, leaf mold, early blight, gray mold of cucumber, scab, powdery mildew, alternaria leaf spot of apple, scab, wheat powdery mildew, rust, banded sclerotial blight, head blight, fruit white rot of grape, brown spot etc.The 3rd, the application of said composition, the resistance that can delay single agent takes place and development.
