Problems solved by technology

[0005] 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

Embodiment 1

[0038] Embodiment 1, the effect of the mixed sterilization of prochloraz and thiabyl copper

[0039] 1. Preparation of medicine

[0040] The prochloraz original drug (98.1%) used in this example was purchased from Zhejiang Lesi Chemical Co., Ltd., the batch number is 20101103; the thiazolin copper (94%) used in the following examples was purchased from Zhejiang Longwan Chemical Co., Ltd. company. The 7 kinds of medicaments (2 kinds of single agents and 5 kinds of mixed medicaments) used in this embodiment are prepared according to the following method:

[0041]The agent prochloraz is a liquid preparation obtained by dissolving prochloraz in dimethyl sulfoxide; the agent thiabyl copper is a liquid suspension obtained by dissolving thiabyl copper in sterile water and ultrasonically ultrasonicating for 30-60 seconds until the liquid suspension is uniform preparation. The mixed agent is obtained by mixing the dimethyl sulfoxide solution of prochloraz and the aqueous solution of...

Abstract

The invention discloses a prochloraz and thiodiazolecopper compound medicament for preventing and controlling rice seed-borne fungus and bacterium diseases. The active ingredients of the medicament comprise N-propyl-N-[alpha-(2,4,6-trichlorophenoxy)-1H-imidazole-1-formamide and 2-amino-5-mercapto-1,3,4-thiodiazole in a mass ratio of (3-9):(7-1). The medicament disclosed by the invention has effects of radically killing seed-borne pathogenic fungi and bacteria and provides new technical support for preventing and controlling spread of rice seed-borne fungus and bacterium diseases and damage.

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 prochloraz and thimethicin copper mixed agent for preventing and controlling rice seed-borne fungal and bacterial diseases. 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 produc...
