Description
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to a powdery mildew resistant bactericidal active agent.
Background
The powdery mildew pathogenic bacteria are pathogenic fungi which are parasitic on the surface of a plant in an obligate way and generate powdery white diseases, belong to the family of ascomycete subfamily powdery mildew, have high parasitic specificity and strong parasitic capacity, and mycelia or conidia can directly invade the epidermis of a host organ through pores after germination to mainly damage young parts of plant leaves, leaf stalks, tender stems, buds, petals and the like, the damaged parts generate near-circular or irregular-shaped powdery spots which can be mutually healed into large pieces with unobvious edges, and white powder is distributed on the large pieces, namely the mycelia, the conidiophores and the conidia of the pathogenic bacteria. In the later period, the white powder turns into grey white or light brown, the leaves are withered yellow and shriveled, and the young leaves are often twisted and withered. In the process of raising seedlings of macadimia nuts, seedlings are often damaged by powdery mildew pathogenic bacteria, at present, chemical agents are mainly used for preventing and treating the macadimia nuts, but the conventional chemical agents are usually narrow in prevention and treatment spectrum, and easily generate the problems of drug resistance, pesticide residue, environmental pollution and the like after long-term large-scale use.
The activated ester is a plant activator such as diazosulfide carboxylic acid developed by Zhangda corporation, and tests show that the mixed use of the activated ester and other medicaments can not only improve the control effect of the activated ester, but also enlarge the disease prevention range of the activated ester. Application No. CN201410612276.5 discloses a bactericidal composition containing amisulbrom and activated ester and application thereof, and specifically discloses a chemical structural formula of the activated ester. The fluxazole activated ester is a novel benzothiadiazole analogue synthesized by eastern university of eastern China, and not only can be used as a plant cell inducer, but also can be used as a plant induced disease-resistant activator. Indoor and field activity tests and experiments performed by multiple domestic scientific research institutes show that the fluxapyrozole active ester can be mixed with a bactericide to improve the bactericidal activity. The application number CN201310034822.7 discloses a pesticide composition containing fluxazole activated ester, specifically discloses the chemical name and structural formula of the fluxazole activated ester, and specifically discloses that the compound of the fluxazole activated ester and metalaxyl, zhongshengmycin, dimethomorph, oxanil, thiram or iprodione has a synergistic effect, so that the control effect can be improved, and the generation of drug resistance can be delayed.
The pesticide active ingredients with different action mechanisms are compounded, and the test judges whether the pesticide compounding has synergism, addition or antagonism, so that the pesticide composition can be used for developing novel chemical pesticides. The inventor discovers that better synergistic effect can be achieved when the fluxapyroxad active ester is compounded with fluxapyroxad, isopyrazam, pyraclostrobin or probenazole within a certain mass ratio range through indoor biological activity tests, and related compounding reports are not seen at present.
