Abstract

The invention relates to a sterilizing composition containing fenpyrazamine. The composition comprises an active component A and an active component B, wherein the active component A is fenpyrazamine, the active component B is selected from one of the following components: boscalid, xemium, peip, fluopicolide, and fluazinam, and the weight ratio of the active component A to the active component B is 1:80 to 60:1. The composition has high activity on a plurality of diseases on a plurality of crops, has prominent synergetic effect at the same time, and thus the bactericidal spectrum is enlarged. Moreover the composition has the characteristics of little use amount, rain washing resistance, and prominent synergetic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fenfluram-containing bactericidal composition on crop diseases. technical background [0002] Fenpyrazamine is a pyridine-based heterocyclic fungicide. Pathogen that inhibits the mechanism of action of the ergosterol biosynthetic pathway, showing inhibition of mycelial growth and spore germination and pollen tube growth. It is mainly used for the prevention and treatment of botrytis, and is used for grapes, cucumbers, citrus, potatoes, peppers, eggplants, ornamental plants, etc. [0003] Boscalid, flufenapyramide, boscalid, flubocalid or fluazinam are all widely used in crop diseases. [0004] In the actual process of agricultural production, the most likely problem in disease prevention and control is the emergence of bacterial resistance. Combination of ingredients from different varieties is a very common method to prevent and control resistant bacteri...
