Description

Sterilization composition containing benziothiazolinone and fluoride ether bacteria amide Technical Field The invention belongs to the field of agriculture, and particularly relates to a sterilization composition containing benziothiazolinone and fluoride ether bacteria amide and application thereof. Background The benziothiazolinone (also called 1,2 benzisothiazolin-3-one) belongs to an isothiazole heterocyclic compound, and is a novel efficient low-toxicity broad-spectrum bactericide, and the action mechanism of the benziothiazolinone is mainly combined with anions or mercapto groups on the surface of a germ cell membrane to destroy the nuclear structure of the germ cell, destroy the synthesis system of protein and the cell membrane, interfere the metabolism of germ cells, inhibit germ reproduction and cause the death of the germ. The compound has good control effect on crops and the like caused by bacteria and fungi. The novel fluoroether bacteria amide (Fluopimomide) is a novel fluorine-containing benzamide bactericide, acts on the respiratory chain of fungi mitochondria, inhibits the activity of succinic dehydrogenase, thus blocking the electron transfer, inhibiting the main stages of fungi spore germination, bud tube elongation, hypha growth and sporocyte formation fungi growth and reproduction, and the sterilization is directly caused by parent active substances without corresponding metabolic activity. The pure fluoroether bacteria amide is white-like powder, is relatively insoluble in water, can be used for preventing and controlling downy mildew, epidemic disease and the like caused by oomycete pathogenic bacteria, can also be used for preventing and controlling diseases such as rice sheath blight, cotton damping-off, cucumber target spot, apple ring spot, apple anthracnose, tomato gray mold and the like, and can be used for various fruits and vegetables, crops, vegetables and the like. CN102086173a discloses a compound fluoroether bacteria amide, and discloses a preparation method thereof and bactericidal activity for preventing and controlling fungal diseases such as epidemic disease, downy mildew and the like. Han Jun et al (Fluor-Em-and pyraclostrobin-against grape downy mildew combined virulence and field control, pesticide science and management) disclose that Fluor-Em-and pyraclostrobin-against downy mildew virulence show a synergistic effect. Zhang Xiuhuan et al (inhibition effect of mixed use of fluoride ether bacteria amide and hexaconazole on sheath blight of rice, pesticide) prove that the mixed use of fluoride ether bacteria amide and hexaconazole has good control effect on rice sheath blight. Meng Runjie et al (synergistic effect of fluoroether bacteria amide and dimethomorph on potato late blight bacteria and field efficacy, pesticide) research shows that the synergistic effect of fluoroether bacteria amide and dimethomorph on potato late blight bacteria is shown by mixing at a specific ratio. Liu Jie et al (synergistic effect of fluoroether bacteria amide and dimethomorph on Conyza and field control effect, pesticide science and management) adopts indoor hypha growth rate method to respectively determine the inhibition effect of fluoroether bacteria amide and dimethomorph and the combination thereof on the pathogenic bacteria of the dasheen epidemic disease, the results show that the fluoroether bacteria amide and the dimethomorph have good control effect on the hyphae of the conomical bacteria, and the fluoroether bacteria amide and the dimethomorph have synergistic effect under a specific proportion. The biological activity of the fluoroether bacteria amide and the valicarb against potato late blight bacteria was explored by the late Hui et al (synergistic effect of the fluoroether bacteria amide and the valicarb against potato late blight bacteria and field control, pesticide). The results show that the fluoroether bacteria amide and the valicarb have good inhibition effect on the growth of the potato late blight bacterial hyphae, and the fluoroether bacteria amide and the valicarb have synergistic effect on the potato late blight under a specific proportion. Cotton damping off, also known as root rot, is an important soil-borne disease caused by the fungus rhizoctonia solani. The pathogen is rhizoctonia solani, and the pathogen can survive in soil for a long time. The infection period is mainly concentrated in the cotton seedling stage, and especially is most fragile in half a month after seedling emergence. Disease symptoms typically manifest as yellowish brown recessed lesions appearing at the seedling stem base, followed by enlargement of the lesions and surrounding the stem, resulting in seedling constriction, wilting, and eventually lodging dead, resulting in "cataplexy". The loss caused by the disease to cotton is extremely serious, which can lead to the seedling shortage and ridge breakage of cotton fields and even needs to be sowed again, thus not only increasing the pr
