The chlorothalonil and cymoxanil compounding pesticide suspending agent provided by the invention has the advantages of high suspensibility and stable product performance.
Description
Technical field
The present invention relates to a kind of tpn and the composite agricultural chemicals suspension agent of white urea cyanogen.
Background technology
Tpn, chemical name: daconil M (2,4,5,6-tetrachloro-1,3-benzene dicarbonitrile), English name: chlorothalonil, No. CAS: 1897-45-6.Efficiently, wide-spectrum bactericide, there is protective effect.Stable to weak acid, weak base and photo-thermal, corrosion-free effect.At plant surface, easily adhere, resistance of rainwater washing against, general 7-10 days of the longevity of residure.Be mainly used in the control of rust, anthracnose, powdery mildew, downy mildew on fruit tree, vegetables.
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, and Peronosporales fungi genus as white in epidemic disease, Peronospora, single shaft frost are belonged to effectively.Frost urea cyanogen is mixed with other protective fungicides extensively, is used in the brassicaceous vegetables such as cucumber, grape, tomato, lichee, huge dish and tobacco etc.
Agricultural chemicals suspension agent is the formulation of 20 century 70 development, has now become one of basic processing formulation.Suspending agent claims again aqueous suspension agent, colloidal suspending agent, concentrated suspension, has cost low, produces, stores and transports and use the features such as safety, and easily mixing 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.Specifically by following technical proposals, be achieved:
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 comprised 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, by 40-60 weight portion succinate sodium 2-ethylhexyl and poly-(Oxy-1,2-ethylidene) non-ionic surface active agent composition 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

Can also in formula, add according to actual needs pH adjusting agent.
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 to 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 μ m.
(3) be placed in homogenizer homogeneous, make particle homogenising.
Tpn of the present invention and the composite agricultural chemicals suspension agent of white urea cyanogen have higher suspension rate, long-term stable storage.Cucumber downy mildew (Pseudoperonospora cubensis) is the Major Diseases in cucumber production, all can fall ill whole breeding time, be characterized in that the oncoming force is violent, propagate fast, disease weight, once crop morbidity, if condition is suitable, PD is exceedingly fast, and can cause a large amount of blades of plant withered in the short time, directly impact is tied melon or is caused ahead of time and uproot plants after their edible portions have been harvested, and causes crop Severe Reduction.The composite agricultural chemicals suspension agent control cucumber downy mildew field effect of tpn of the present invention and white urea cyanogen is tested, and result shows, better to the preventive effect of cucumber downy mildew.
Embodiment
Embodiment 1
