Abstract

The present invention discloses a bactericide composition and applications thereof, wherein the bactericide composition contains active ingredients such as Shenqinmycin and iprodione, and a weight ratio of Shenqinmycin to iprodione is 1:(1-100). According to the present invention, the bactericide composition provides significant prevention and control effects in the field of crop disease prevention and control, has characteristics of broad prevention and control spectrum, good prevention and control effect, single active ingredient and drug resistance generation resistance, provides synergistic effects for a variety of pathogenic bacteria, and can treat a variety of mixed occurring diseases.

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 which has good control effect, is not easy to produce drug resistance and can also treat mixed diseases. [0004] In order to achieve the above object, the present invention provides a fun...
