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
The invention belongs to formulations of pesticide manufacture field, relate to the novel form of agricultural fungicide difenoconazole, specifically, the present invention relates to a kind of difenoconazole emulsible powder.
Background technology
The chemical name of Difenoconazole (difenoconazole) is: 1-{2-(4-(4-chlorophenoxy)-2-chlorphenyl }-the 4-methyl isophthalic acid, 3-dioxin-pentane-2-ylmethyl)-1-H-1,2; The 4-triazole; Belonging to azoles fungicide, have good interior absorption, is sterol demethylation inhibitor.The existing at present formulation products of Difenoconazole: single agent is formulations such as missible oil, suspending agent, water dispersion granule, and the mixture of processing with other former medicines: formulations such as missible oil, wetting powder, suspension seed-coating agent.There are following shortcoming in missible oil, water dispersion granule, three kinds of preparation formulations of suspending agent: 1. suspending agent, water dispersion granule are compared the cost of material height with this preparation, and the suspending agent poor stability should not be stored; 2. organic solvent content such as xylol is higher relatively in the missible oil, and environmental pollution is serious, and the transport and store poor stability.
Summary of the invention
The objective of the invention is: provide a kind of safety, environmental protection, stable storage, drug effect and missible oil suitable difenoconazole emulsible powder.
The technical scheme that realizes the object of the invention is: a kind of difenoconazole emulsible powder, and it is to be the disinfectant use in agriculture of active ingredient with the difenoconazole technical material, but its formulation is an emulsified powder;
But each component and the mass fraction thereof that constitute emulsified powder are: Difenoconazole 5%～60%; Solvent 0%～5%; Dispersant 0.5%～10%; Emulsifier 0.5%～30%; Wetting agent 0%～8%; Suspending agent 0.1%～5%; Surplus is a carrier.
In the above-mentioned difenoconazole emulsible powder, but each component and the mass fraction thereof of formation emulsified powder are: Difenoconazole 5%～60%; Solvent 0%～5%; Dispersant 0.5%～10%; Emulsifier 0.5%～30%; Wetting agent 0%～8%; Suspending agent 0.1%～5%; Surplus is a carrier.
In the above-mentioned difenoconazole emulsible powder, said solvent is solvent naphtha, ten four carbon alcohols, xylol, toluene, cyclohexanone, N, a kind of in dinethylformamide, the alkyl pyrrolidone; Dispersant is a kind of among sodium lignin sulfonate, calcium lignosulfonate, Dispersant MF, dispersing agent C NF, dispersant NNO, the dispersant S; Emulsifier is a farming breast 100, farming breast 500, farming breast 600, Nongru-700, one or more in the Difenoconazole emulsifier; Wetting agent is one or more in bay alcohol radical sodium sulphate, neopelex, lauryl sodium sulfate, the wetting agent jfc; Suspending agent is one or more in methylcellulose, carboxymethyl cellulose, xanthans, sodium alginate, industrial starch, the sucrose; Carrier is one or more in diatomite, bentonite, kaolin, attapulgite, white carbon black, precipitated calcium carbonate, the potter's clay.
In the above-mentioned difenoconazole emulsible powder, preferred dispersants is sodium lignin sulfonate or Dispersant MF; Emulsifier is the combination of Difenoconazole emulsifier or farming breast 500, farming breast 600 and Nongru-700; Wetting agent is lauryl sodium sulfate or wetting agent jfc; Suspending agent is carboxymethyl cellulose or xanthans; Carrier is potter's clay and white carbon black
Technique effect of the present invention is: but the present invention's emulsified powder; Because each component collocation rationally, an amount of emulsifier of particularly allocating into guarantees that more its active ingredient Difenoconazole can reach emulsified state in use in water, make the Difenoconazole drug effect be not fully exerted; Its drug effect of evidence and Difenoconazole missible oil is (seeing table 5) quite; And contained organic solvent is less than missible oil and aqueous emulsion far away, and environmental pollution is little, and it is good to store with Transport Safety; And wetting powder, water dispersion granule difficult emulsification in water can not guarantee that the Difenoconazole drug effect in the preparation is not fully exerted; Suspending agent not only cost of material is high, and poor storage stability.
