Tebuconazole and thiodiazole-copper blended medicament for preventing and treating rice seed-borne fungal and bacterial diseases

Abstract

The invention discloses a tebuconazole and thiodiazole-copper blended medicament for preventing and treating rice seed-borne fungal and bacterial diseases. The medicament comprises the following active ingredients: (RS)-1-p-chlorophenyl-4,4-dimethyl-3-(1H-1,2,4-triazole-1-ylmethyl)pentyl-3-alcohol and 2-amino-5-sulfydryl-1,3,4-thiadiazole copper, wherein the mass ratio of the (RS)-1-p-chlorophenyl-4,4-dimethyl-3-(1H-1,2,4-triazole-1-ylmethyl)pentyl-3-alcohol to the 2-amino-5-sulfydryl-1,3,4-thiadiazole copper is (1-9):(9-1). The medicament disclosed by the invention has an effect on thoroughly killing pathogenic fungi and bacteria carried in seeds, thereby providing a new technical support for preventing and controlling the propagation, spread and harm of rice seed-borne fungal and bacterial diseases in production.

Description

technical field [0001] The invention relates to a bactericide for preventing and treating plant seed-borne bacterial and fungal diseases, in particular to a mixed medicament for preventing and treating rice seed-borne fungal and bacterial diseases of tebuconazole and thiabactin copper. Background technique [0002] Rice is one of the two most important food crops in the world, its cultivated area and total output are second only to wheat. Rice is also the most important food crop in my country. The total area, total output and output per unit area of ​​rice rank first in my country's food crops. In the process of rice production, rice diseases are the main factors restricting the yield and quality of rice, causing huge economic losses, especially the three major diseases of rice blast, rice sheath blight, and rice bacterial blight, as well as rice bakanae disease, The occurrence of diseases such as rice bacterial streak disease has become the most important disease in rice ...

AI Technical Summary

Problems solved by technology

[0006] Rice seeds usually carry pathogenic bacteria of various diseases including fungi and bacteria, and the treatment of rice seeds with a single agent cannot achieve thorough disinfection and health care treatment of fungi and bacteria carried by seeds during production, so that some agents that are not suitable for use Sensitive pathogens survive and spread with the transportation of seeds, sowing, and seedling growth, causing field diseases and damage
