Description

Sterilization composition containing benziothiazolinone and Inpyrfluxam Technical Field The invention belongs to the field of agriculture, and particularly relates to a sterilization composition containing benziothiazolinone and Inpyrfluxam 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. Inpyrfluxam is succinic dehydrogenase inhibitor (SDHI) bactericide, which can inhibit mitochondrial function, prevent energy generation, inhibit growth of pathogenic bacteria and finally cause death by interfering complex II on respiratory electron transfer chain of pathogenic bacteria mitochondria. Can be applied to wheat, corn, rice, sorghum, peanut, potato, soybean, rape, beet, fruit tree, vegetable and the like, and can prevent and treat various diseases such as rice sheath blight, grape powdery mildew, wheat leaf blight, barley net blotch, wheat scab and the like. CN109452287a discloses a bactericidal composition containing Dichlobentiazox and Inpyrfluxam for controlling various diseases such as rice sheath blight, rice blast, grape powdery mildew, apple scab, cucumber anthracnose and the like. CN116209355A discloses a fungicidal composition comprising penconazole, inpyrfluxam and a third compound active ingredient. Is used for preventing and controlling fungus diseases such as wheat leaf blight, barley net blotch and the like. The rice sheath blight disease is one of the most widely distributed and most harmful diseases on rice, and is mainly caused by rhizoctonia solani infection. Pathogenic bacteria mainly use sclerotium to overwinter in soil, and float water surface to infect rice plants in the next year. The disease mainly occurs on leaf sheaths and leaves, and is a water stain-like dark green small spot at the initial stage, and then expands into an elliptic or moire-like large spot, and the edge is brown and the center is grey. When the humidity is high, white spider silk mycelium can be seen in the affected part, and brown sclerotium which is easy to fall off is formed in the later period. Diseases develop rapidly under the conditions of high temperature and high humidity, and especially after rice is sealed, the diseases are easy to prevail when the field is shaded and the humidity is high. The incidence of excessive nitrogen fertilizer application and excessive close planting in the field is often more serious. Wheat scab is a destructive spike disease, not only causes yield reduction, but also causes great threat to human and livestock health by toxins produced by germs. In the early stage of the disease, water-stain brown spots appear on glumes, part or the whole spikelet is withered and yellow after the water-stain brown spots spread, pink or orange mould layers are generated on the affected part when the water-stain brown spots are wet, and black small particles can be generated in the later stage. The infected kernels shrink and lose luster. The pathogenic bacteria overwintere on crop residues such as cornstalks, rice piles and the like, and the disease popularity and the weather relationship in the flowering period are very close. At present, no report related to the compounding of the benziothiazolinone and Inpyrfluxam in the prior art is found. Disclosure of Invention The invention aims at screening effective compound medicaments for diseases which are common in agricultural production such as rice sheath blight disease, wheat scab and the like but are difficult to control in the prior art. The inventor finds that the benziothiazolinone and Inpyrfluxam have obvious synergistic effect after being compounded, can effectively prevent and treat various agricultural diseases including the two diseases, and completes the invention based on the research. One aspect of the invention relates to a bactericidal active ingredient composition, wherein the bactericidal active ingredient composition contains two active ingredients of benziothiazolinone and Inpyrfluxam. In the bactericidal active ingredient composition of the invention, the weight ratio of the benziothiazolinone to Inpyrfluxam is 1:120 to 120:1, preferably 1:60 to 60:1, more preferably 1:30 to 30:1. For example ：30:1、29:1、28:1、27:1、26:1、25:1、24:1、23:1、22:1、21:1、20:1、19:1、18:1、17:1、16:1、15:1、14:1、13:1、12:1、11:1、10:1、9:1、8:1、7:1、6:1、5:1、4:1、3:1、2:1、1:1、1:2、1:3、1:4、1:5、1:6、1:7、1:8、1:9、1:10、1:11、1:12、1:13、1:14、1:15、1:16、1:17、1:18、1:19、1:20、1:21、1:22、1:23、1:
