Abstract
The invention relates to an emulsifiable powder of a preparation of Cyprodinil and triazole fungicide, which is a pesticide fungicide taking a Cyprodinil active compound and a triazole fungicide as active ingredients, and the dosage formation can be emulsifiable powder. The emulsifiable powder comprises the following components by mass percent: 5-60% of collarium, 5-60% of triazole fungicide, 0-5% of solvent, 0.5-0.10% of dispersing agent, 0.5-30% of emulsifier, 0-8% of wetting agent, 0.1-5% of suspending agent and the balance of carriers. Because of the reasonable matching of the components of the emulsifiable powder in the invention, especially the added proper amount of emulsifier, the Cyprodinil and triazole fungicide can be guaranteed to be in an emulsifiable state in the water during using, so that the pesticide effects of the Cyprodinil and triazole fungicide can be given into a full play, and the contained organic solvent is much less than missible oil and emulsion in water, the environmental pollution is small, the storage and transportation safety is good, the process is simple and the process cost is low.
Description
Technical field
The invention belongs to formulations of pesticide manufacture field, the novel form that relates to the triazole bactericidal agent complex preparations such as disinfectant use in agriculture cyprodinil and own azoles alcohol, Tebuconazole, Flutriafol, propiconazole, Difenoconazole, epoxiconazole, prothioconazoles, specifically, but the present invention relates to the emulsified powder of a kind of cyprodinil and triazole bactericidal agent complex preparation.
Background technology
The chemical name of cyprodinil (Cyprodinil) is: 4-cyclopropyl-6-methyl-N-phenyl pyrimidine-2-amine; belong to the aminopyrimidine bactericide; have protection, treatment, blade penetrates and the root systemic activity, is the methionine biosynthesis inhibitor, with triazole bactericidal agent without cross resistance.Cyprodinil has formulation products at present mainly take the water dispersion granule formulation as main, but the water dispersion granule formulation is compared the cost of material height much with this preparation.
Common feature is to contain hydroxyl (ketone group), substituted-phenyl and 1,2,4-triazole group compound on the main chain on the triazole bactericidal agent chemical constitution.This class medicament is except to the oomycetes non-activity in the Mastigomycotina, and the pathogen of Ascomycotina, Basidiomycotina and Deuteromycotina is all had activity, and its mechanism of action is damaged somatic cells film function for to affect the sterols biosynthesis.Triazole bactericidal agent is used widely at pesticide field at present, and its preparation formulation kind is also a lot, is generally missible oil, wetting powder, suspending agent, water dispersion granule etc., and mainly there is following shortcoming in these formulations:
Suspending agent, water dispersion granule are compared the cost of material height with this preparation, the suspending agent poor stability should not be stored;
The organic solvent contents such as the dimethylbenzene in the missible oil are relatively high, and environmental pollution is serious, and the transportation storing stability is poor.
Summary of the invention
The objective of the invention is: but cyprodinil that a kind of safety, environmental protection, stable storage, drug effect be higher than other common formulations and the emulsified powder of triazole bactericidal agent complex preparation are provided.
Be to realize the object of the invention, but the invention provides the emulsified powder of a kind of cyprodinil and triazole bactericidal agent complex preparation, it is the agriculture chemicals fungicide take the former medicine of cyprodinil and the former medicine of triazole bactericidal agent as active ingredient, but its formulation is emulsified powder.
But each component and mass percent thereof that emulsified powder of the present invention comprises are: cyprodinil 5%-60%; Triazole bactericidal agent 5%-60%; Solvent 0%-5%; Dispersant 0.5%-10%; Emulsifier 0.5%-30%; Wetting agent 0%-8%; Suspending agent 0.1%-5%; Surplus is carrier.
Described triazole bactericidal agent is one or more in own azoles alcohol, Tebuconazole, Flutriafol, propiconazole, Difenoconazole, epoxiconazole, the prothioconazoles.
Described solvent is solvent naphtha, a kind of in ten four carbon alcohols, dimethylbenzene, toluene, cyclohexanone, DMF, the alkyl pyrrolidone, and solvent quality is relatively less, therefore can reduce oxious component in the solvent to environment.
Described dispersant is a kind of among sodium lignin sulfonate, calcium lignosulfonate, Dispersant MF, dispersing agent C NF, dispersant NNO, the dispersant S, and dispersant helps each component is uniformly dispersed.
Described emulsifier is one or more in farming breast 100, farming breast 500, farming breast 600, the Nongru-700, emulsifier can guarantee that active ingredient cyprodinil and triazole bactericidal agent can reach emulsified state in use in water, so that cyprodinil and triazole bactericidal agent drug effect are not fully exerted.
Described wetting agent is one or more in bay alcohol radical sodium sulphate, neopelex, lauryl sodium sulfate, the wetting agent jfc, wetting agent is by reducing material surface tension force tension force or interfacial tension, makes that substance is more abundant to be mixed with solvent and other components.
Described suspending agent is one or more in methylcellulose, carboxymethyl cellulose, xanthans, sodium alginate, industrial starch, the sucrose, suspending agent can increase settling velocity or the increase particulate hydrophilic additives of viscosity to reduce particulate of dispersion medium, makes dispersion medium be difficult for precipitating.
Described carrier is one or more in diatomite, bentonite, kaolin, attapulgite, White Carbon black, precipitated calcium carbonate, the potter's clay.
But in the emulsified powder of above-mentioned cyprodinil and triazole bactericidal agent complex preparation, preferred dispersants is sodium lignin sulfonate or Dispersant MF; Emulsifier is the combination of farming breast 500, farming breast 600, 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 is emulsified powder, because each component collocation rationally, the an amount of emulsifier of particularly allocating into guarantees that more its active ingredient cyprodinil and triazole bactericidal agent can reach emulsified state in use in water, so that cyprodinil and triazole bactericidal agent drug effect are not fully exerted, drug effect (seeing Table 5) when the general formulation that its drug effect of evidence is better than single dose cyprodinil water dispersion granule and triazole bactericidal agent is used with, and contained organic solvent is far less than missible oil and aqueous emulsion, environmental pollution is little, it is good to store with Transport Safety, processing technology is simple, and processing cost is low; And wetting powder, water dispersion granule difficult emulsification in water can not guarantee that the active ingredient in the preparation is not fully exerted, and suspending agent then not only cost of material is high, and poor storage stability.
