Problems solved by technology

There are following disadvantages in the formulations of emulsifiable concentrate, water-dispersible granule and suspending agent: 1. Compared with this preparation, the raw material cost of suspending agent and water-dispersing granule is high, and the stability of suspending agent is poor, so it is not suitable for storage; 2. The content of organic solvents such as xylene in the emulsifiable concentrate Relatively high, serious environmental pollution, and poor transportation and storage safety

Abstract

The invention relates to difenoconazole emulsible powder, which is agricultural germicide taking original difenoconazole as effective constituents and the dosage form is emulsible powder; the emulsible powder is constituted by the following constituents in percentage by the mass fraction: 5-60% of difenoconazole, 0-5% of solvent, 0.5-10% of dispersing agent, 0.5-30% of emulsifier, 0-8% of wetting agent, 0.1-5% of suspending agent and the balance of carrier. The optimized dispersing agent is sodium lignosulfonate or the dispersing agent MF; the emulsifier is difenoconazole emulsifier or the combination of pesticide emulsifier 500 or pesticide emulsifier 600 and pesticide emulsifier 700; the wetting agent is lauryl sodium sulfate or wetting agent JFC; the suspending agent is carboxymethyl cellulose or xanthan gum; the carrier is pot clay and white carbon black. Tests prove that the pesticide effect of emulsible powder in the invention corresponds to that of difenoconazole missible oil, and the contained organic solvent is far less than the missible oil and emulsion in water, thus having little contamination on the environment and good storage and transportation safety.

Description

technical field [0001] The invention belongs to the field of pesticide dosage form processing, and relates to a new dosage form of the agricultural fungicide difenoconazole. Specifically, the invention relates to a difenoconazole emulsifiable powder. Background technique [0002] The chemical name of difenoconazole is: 1-{2-[4-(4-chlorophenoxy]-2-chlorophenyl}-4-methyl-1,3-dioxolane -2-ylmethyl)-1-H-1,2,4-triazole, which belongs to azole fungicides, has good systemic property and is a sterol demethylation inhibitor. Difenoconazole currently has preparation products: single doses are emulsifiable concentrates, suspension concentrates, water-dispersible granules, etc., and mixed formulations with other original drugs: emulsifiable concentrates, wettable powders, suspension seed coatings, etc. Formulations. There are following disadvantages in the formulations of emulsifiable concentrate, water-dispersible granule and suspending agent: 1. Compared with this preparation, the ra...
