Sterilization composition and application thereof

Abstract

The invention discloses a sterilization composition and application thereof. The active constituent of the sterilization composition comprises a mixture of 8-hydroxyquinoline and/or derivate thereof at a mass ratio which is not zero. The sterilization composition is capable of achieving an effect of curing multiple types of plant pathogens, especially banana vascular wilt and downy mildew; the cure rate is averagely not less than 99%; when used in time, the sterilization composition does not influence the fruit yield and the fruit quality; the sterilization composition is not only high in pesticide effect, less in pollution and not beneficial to generation of pesticide resistance of pathogenic bacteria.

Description

technical field [0001] The invention relates to a bactericidal composition and application thereof, belonging to the field of bactericides. Background technique [0002] Banana yellow leaf disease, also known as banana Panama disease, is an infectious disease of bananas transmitted through the soil. The infected bananas gradually wither and die, and because of the legacy of the soil, bananas cannot be grown in the diseased area for more than 30 years. It is an "incurable disease" of bananas. It is also the biggest killer threatening the global banana planting industry. The external symptoms are that the lower old leaves of the affected banana plant first turn yellow, and gradually expand to the middle rib, the petiole softens, bends and droops, and finally withers, and the upper young leaves also gradually turn yellow, and finally the whole banana plant withers and dies. Leaf sheaths around the pseudostem of the plant undergo longitudinal fissures from the base; the interna...
