Abstract

The invention discloses a sterilization composition, and belongs to the field of agricultural bactericides. An active component of the sterilization composition comprises bacillus subtilis and polyoxin. The sterilization composition comprises 10 to 85 wt% of the active component. The active component comprises 10 to 70 wt% of bacillus subtilis. The invention also discloses a use of the sterilization composition in prevention and treatment of grey mould fruit rot of strawberry, cucumber fusarium wilt and rice sheath blight. Compared with a sterilization preparation prepared only from polyoxin or bacillus subtilis as an active component, the sterilization composition provided by the invention has better effects and activity of prevention and treatment of grey mould fruit rot of strawberry, cucumber fusarium wilt and rice sheath blight. Because of different mechanisms of effects produced by bacillus subtilis and polyoxin in the active component, polyoxin resistance is relieved and a sterilization composition service life is prolonged.

Description

technical field [0001] The invention relates to an agricultural bactericidal agent and its application, in particular to a bactericidal composition and its application. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the society has put forward higher requirements for the quality and safety of agricultural products. Many crops are prone to pests and diseases due to the large-scale and large-scale production management mode. For example, in recent years, the occurrence frequency of gray mold of strawberry has become higher and higher, and the disease has become more and more serious, which has become a restrictive factor for strawberry production; large-scale planting of cucumber and tomato will also cause fusarium wilt; another example is rice sheath blight. In recent years, due to the large-scale planting of late-maturing high-quality and high-yield rice varieties, as well as the ...
