Abstract

The invention discloses a bactericide composition and application thereof. The bactericide composition contains active ingredients, namely phenazino-1-carboxylic acid and fluazinam, and the weight ratio of phenazino-1-carboxylic acid to fluazinam is 1:(0.02-50). The bactericide composition is capable of simultaneously treating various diseases, has the characteristics of broad preventing and treating spectrum and good preventing and treating effects, has synergistic effects on multiple germs, and contains non-single active ingredients so that drug resistance is not easy to generate.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a fungicide composition and its application. Background technique [0002] In recent years, with the refinement of planting and the increase in the frequency and dosage of pesticides, the resistance of crop diseases has developed rapidly, and the difficulty of prevention and control has increased. In addition, in agricultural production, multiple diseases often occur together, which increases the difficulty of prevention and control. Therefore, the market is in urgent need of high-efficiency, broad-spectrum fungicides to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, and provide a fungicide composition with broad control spectrum, good control effect and not easy to produce drug resistance. [0004] In order to achieve the above object, the present invention provides a bactericide compos...
