Abstract

The present invention relates to a phenoxy bacterioester water dispersing granules preparation and a phenoxy bacterioester water suspension agent, the former is a granules preparation obtained by mixing phenoxy bacterioester with adjuvant and pilling material together, and can be quickly disintegrated in water, dispersed and formed into high suspended and stable dispersion system, and the latter is a high-dispersity and stable liquid preparation using water as medium and obtained by mixing phenoxy bacterioester together with adjuvant and water. As compared with wettable powder preparation said two preparations are large in density, small in volume, have good dispersity and high suspension rate, and can raise control effect.

Description

1. Technical field [0001] The present invention relates to a new preparation of agricultural bactericide, specifically two preparations of bactericide phenoxystrobin, namely phenoxystrobin water dispersible granules (WDG) and phenoxystrobin aqueous suspension (SC) . 2. Background technology [0002] Kresoxim-methyl, also known as pyraclostrobin, is a methoxyacrylate fungicide. [0003] Structural formula: [0004] [0005] The chemical name is: [0006] (E)-α-Methoxyimino-2-[(2-methylphenoxy)-methyl]phenylacetate methyl ester. Mainly used in wheat, corn, sorghum, rice, fruit trees, vegetables, potatoes and other crops, and has the ability to treat and protect most diseases caused by pathogenic fungi such as Ascomycetes, Basidiomycetes, Deuteromycetes and Oomycetes and eradication. It is a new and excellent variety that has received considerable attention at home and abroad in recent years. CN1237088A discloses a method for controlling fungi with this compound, but d...
