Frost urea cyanogen, 1-(2-cyano group-2-methoxyl group imido grpup)-3-ethyl carbamide, English name: cymoxanil, No. CAS: 57966-95-7.Frost urea cyanogen is a kind of efficient, low toxicity bactericide, to Peronosporales fungi as epidemic disease frost genus, Peronospora, single shaft frost belong to effectively.Frost urea cyanogen is mixed with other protective fungicides extensively, is used in brassicaceous vegetable and the tobaccos etc. such as cucumber, grape, tomato, lichee, huge dish.
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, has cost low, the features such as production, storing and use safety, and easily mixes with water, easy to use.
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 tpn and the composite agricultural chemicals suspension agent of white urea cyanogen.Be achieved especially by following technical proposals:
Tpn and the composite agricultural chemicals suspension agent of white urea cyanogen, comprise the raw material of following weight percentage: tpn 8-12%; Frost urea cyanogen 6-10%.
Tpn and the composite agricultural chemicals suspension agent of white urea cyanogen, be made up of following materials by weight percentage: tpn 8-12%; Frost urea cyanogen 6-10%; Surfactant 5-9%; Propane diols 5-7%; Magnesiumaluminumsilicate 0.05-0.15%; Diethyl silicone oil 0.1-0.3%; Ethylparaben 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.
Tpn of the present invention and the composite agricultural chemicals suspension agent of white urea cyanogen 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, tpn, white urea cyanogen, surfactant, propane diols, Magnesiumaluminumsilicate, diethyl silicone oil, ethylparaben 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.
Tpn of the present invention and the composite agricultural chemicals suspension agent of white urea cyanogen have higher suspension rate, stable during long-term storage.Cucumber downy mildew (Pseudoperonosporacubensis) is the Major Diseases in cucumber production, whole breeding time all can fall ill, be characterized in that the oncoming force is violent, propagate fast, disease weight, crop is once morbidity, if condition is suitable for, PD is exceedingly fast, and a large amount of blade of plant can be caused in the short time withered, direct impact is tied melon or is caused and uproots plants after their edible portions have been harvested ahead of time, causes crop Severe Reduction.Tpn of the present invention and the composite agricultural chemicals suspension agent control cucumber downy mildew field efficacy of white urea cyanogen are tested, and result shows, better to the preventive effect of cucumber downy mildew.
Embodiment
Embodiment 1
(1) according to formula, tpn, white urea cyanogen, surfactant, propane diols, Magnesiumaluminumsilicate, diethyl silicone oil, ethylparaben 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 2.8 μm.
Table 1: tpn and the composite agricultural chemicals suspension agent formula table unit of white urea cyanogen: kilogram
