Compound bactericidal composition containing fludioxonil

Abstract

The invention relates to a compound bactericidal composition containing fludioxonil and use thereof. The effective components of the composition are fludioxonil and hymexazol, the mass ratio of portions of fludioxonil and hymexazol is 20:1 to 1:50. The bactericidal composition has relatively strong synergistic action, widens disease prevention and treatment spectrum, can prevent germ from generating resistance or delay the development speed of resistance, prolongs the use life of the pesticide, and reduces the use cost and pesticide residue. The compound bactericidal composition can prevent and treat fusarium patch, rice seedling rot, pythium aphanidermatum, fusarium wilt, verticillium wilt, sclerotinia sclerotiorum, colletotrichum lagenarium, phytophthora blight, fusarium wilt, cladosporium cucumerinum, sclerotium erwinia carotovora, seedling blight, stem wilt and leaf blight, and is particularly suitable for preventing and treating crop soil diseases resulted from pathogen fungus such as fusarium graminearum schwabe, rhizoctinia, pythium aphanidermatum, seedling rot fusoma, phytophthora capsici and the like.

Description

technical field

[0001] The invention relates to an agricultural fungicidal composition and its application, in particular to a fungicidal composition with fludioxonil and hymexazol as main active ingredients and its application. Background technique

[0002] During the growth and development of crops, they are vulnerable to various diseases, especially fungal diseases, which are of various types and cause serious harm. Soil-borne fungal diseases are even more difficult to control plant diseases, and it goes without saying that they cause damage to crop growth and yield. For a long time, chemical control has been the main effective means to control soil-borne diseases. Due to unscientific farming methods such as continuous cropping for many years, the pathogenic bacteria in the soil have accumulated for many years and cannot be effectively removed. In addition, single drug use and other unscientific drug use methods have resulted in a variety of soil-borne pathogenic bacteri...
