Description
Technical field
The present invention relates to a kind of prochloraz iprodione suspending agent.
Background technology
Prochloraz, english common name: PROCHLORAZ, chemical name: N-propyl group-N-[2-(2,4,6-Trichlorophenoxy) ethyl]-imidazoles-1-formamide, No. CAS: 67747-09-5, it is a kind of wide-spectrum bactericide, to the disease that various crop is caused by sac fungi and imperfect fungus, there is obvious preventive effect, also can be mixed with most of bactericide, bactericide, Insecticides (tech) & Herbicides (tech), all there is good control efficiency.To the multiple diseases on field crop, fruit and vegetable, turf and ornamental plants, there is treatment and eradicant action.
Iprodione, chemical name: 3-(3,5-dichlorophenyl)-N-isopropyl-2,4-dioxoimidazolidin-1-carboxylic acid amides, English name Iprodione, No. CAS: 36734-19-7, be dicarboximide class high-efficiency broad spectrum, contact killing type bactericide.Be applicable to prevent and treat the diseases such as crop early defoliation disease, gray mold, early blight such as multiple fruit tree, vegetables, melon and fruit class.
Agricultural chemicals suspension agent is the formulation of 20 century 70 development, has now become one of basic processing formulation.Suspending agent, also known as aqueous suspension agent, colloidal suspending agent, concentrated suspension, is under surfactant and other promoter effects, is distributed in water, forms uniform and stable thick suspension system by the former medicine being insoluble to or being insoluble in water.Because its dispersion medium is water, thus suspending agent to have cost low, to produce, the feature such as storing and use safety, and easily mix with water, easy to use.Compared with taking organic solvent as the formulations of pesticide of medium, there is the advantages such as little to environmental influence of poisoning be light.
Summary of the invention
For solving the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of prochloraz iprodione suspending agent.Be achieved especially by following technical proposals:
Prochloraz iprodione suspending agent, comprises the raw material of following weight percentage: Prochloraz 6-10%; Iprodione 6-10%.
Prochloraz iprodione suspending agent, is made up of following materials by weight percentage: Prochloraz 6-10%; Iprodione 6-10%; Surfactant 5-9%; Ethylene glycol 5-7%; Carboxymethyl cellulose 0.05-0.15%; Dimethicone 0.1-0.3%; Sodium salicylate 0.01-0.03%; Surplus is water.
Described surfactant is poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of succinate sodium 2-ethylhexyl and/or α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Described surfactant, is made up of 40-60 weight portion succinate sodium 2-ethylhexyl and poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of 40-60 weight portion α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, CAS:64422-66-8, molecular formula: (C

24o.Succinate sodium 2-ethylhexyl, also known as: Aerosol OT, No. CAS: 577-11-7.
PH adjusting agent can also be added according to actual needs in formula.
Prochloraz iprodione suspending agent of the present invention can adopt the general method in this area to be prepared, and one is ultramicro grinding method, and another kind is coacervation.
Concrete, described ultramicro grinding method:
(1) according to formula, Prochloraz, iprodione, surfactant, ethylene glycol, carboxymethyl cellulose, dimethicone, sodium salicylate and water are uniformly mixed pulp thing, are placed in ball mill and pulverize.
(2) be placed in skin grinder and carry out ultramicro grinding, control average grain diameter 2-4 μm.
(3) be placed in homogenizer homogeneous, make particle homogenization.
Prochloraz iprodione suspending agent of the present invention has higher suspension rate, stable during long-term storage.Agricultural chemicals suspension agent of the present invention is a kind of interior absorption broad spectrum type bactericide, has certain therapeutic action simultaneously, also plays systemic action by root absorption.Can effectively prevent and treat fungi benzimidazole systemic fungicide being had to resistance.Have treatment protection and wait multiple action, work by suppressing the biosynthesis of sterol, without systemic action, the multiple diseases preventive effect caused for sac fungi and imperfect fungus is splendid.Adopt gene induced technology, activated plant disease-resistant gene is expressed, and quick-acting is good, and the lasting period is long, uses control gourd, fruit and vegetable without systemic action controlling object routine.Suitable for crop: apple, pears, cherry, melon, tomato, capsicum, vegetables etc., controlling object: scab, shot hole, decayed fruit disease, powdery mildew, leaf spot, rust, anthracnose, black spot, anthrachose of grape, blight dis-ease, grey scab, gray mold etc.
Embodiment
Embodiment 1
(1) according to formula, Prochloraz, iprodione, surfactant, ethylene glycol, carboxymethyl cellulose, dimethicone, sodium salicylate and water are uniformly mixed pulp thing, are placed in ball mill and pulverize.
(2) be placed in skin grinder and carry out ultramicro grinding, control average grain diameter 2-4 μm.
(3) be placed in homogenizer homogeneous, make particle homogenization.
Obtained suspending agent, the liquid of outward appearance thickness homogeneous phase, measure through Malvern laser fineness gage, its average grain diameter (D50) is 3.0 μm.
Table 1: prochloraz iprodione suspending agent formula table unit: kilogram
