Abstract

The invention provides a bactericidal composition containing benzisothiazolinones and oxathiapiprolin, the bactericidal composition contains two active components of A and B, the active component A isa compound with the structure of formula I, the active component B is oxathiapiprolin, and the weight ratio of A to B is 20-1:1-20. The invention also provides a preparation method and application ofthe composition. The test results show that, the bactericidal composition has obvious synergistic effect, more important, the application amount is reduced, and the use cost is reduced. The bactericidal composition can effectively prevent and treat certain bacterial or fungal diseases of crops. By compounding of bactericides of different mechanisms and modes of action, the bactericidal composition has very good effects on expanding the bactericidal spectrum, delaying the fungal and bacterial resistance, improving the control effect and other aspects.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, and in particular relates to a bactericidal composition with improved properties, in particular to a bactericidal composition comprising benzisothiazolinones and fluthiazolinone. Background technique [0002] Benzisothiazolinone compounds are a new type of broad-spectrum fungicides, which are mainly used to prevent and treat various bacterial and fungal diseases of cereal crops, vegetables, and fruits. The mechanism of its bactericidal action mainly includes two aspects: destroying the nucleus structure of germs, causing them to lose their heart parts and dying of failure, and interfering with the metabolism of germ cells, making them physiologically disordered and eventually leading to death. Using it at the early stage of disease can effectively protect plants from pathogens, and increasing the dosage after disease occurs can obviously control the spread of pathogens, so as to achie...
