Abstract
The invention relates to seed treatment dispersible powder, which is prepared by the following components in percentage by weight: thifluzamide 1%-85%, agricultural film-forming agent 1%-5%, agricultural warning coloring agent 1%-5%, and the balance of agricultural preparation auxiliary element, and the total percentage by weight of all the components is 100%. The invention aims to solve the following problems: the thifluzamide in the prior art is mainly used as suspending agent, wettable powder and water dispersible granules of bactericide, and is mainly used for later treatment after crop diseases, while the seed treatment dispersible powder is mainly used for seed dressing of plants, and takes precautions against the plant diseases. The technical key point lies in that the thifluzamide is mixed with appropriate wetting dispersant, agricultural film-forming agent, agricultural warning coloring agent, inert filler and the like to prepare the pesticide preparation, which protects crops, reduces the pesticide usage amount and improves the crop quality.
Description
Technical field
But the present invention relates to a kind of seed treatment dispersion powder and preparation method thereof, but be specifically related to a kind of seed treatment dispersion powder that contains the thifluzamide bactericide and preparation method thereof.
Background technology
Thifluzamide (thifluzamide), chemical name are 2', 6'-two bromo-2-methyl-4'-trifluoromethoxy-4-Trifluoromethyl-1, and 3-thiadiazoles-5-hydroxyl anilide, structure is:
It belongs to the thiazole amide bactericide, has strong interior conductivity and the long lasting effect of inhaling.Thifluzamide is the succinate dehydrogenase inhibitor, because fluorine-containing, its its competitiveness in biochemical pathway is very strong, in case be combined with regard to difficult recovery with substrate or enzyme.Thifluzamide all has activity to pathomycetes such as Rhizoctonia, Puccinia, Ustilago, Tilletia, corticium, nuclear cavity Pseudomonas, especially the fungus-caused disease of Basidiomycetes such as banded sclerotial blight, damping off etc. is had special efficacy.
Present thifluzamide preparation is suspending agent, wetting powder, water dispersible granules.Mainly be take the foliar spray control as main, and the also not application on seed treatment.
