Difenoconazole emulsible powder
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.
