Description
Technical field
The present invention relates to a kind of Isoprothiolane and the composite agricultural chemicals suspension agent of own azoles alcohol.
Background technology
Isoprothiolane, 1,3-bis-sulphur pentane-2-pitches Diisopropyl malonate, English name: Isoprothiolane, No. CAS: 50512-35-1.Efficient systemic fungicide is the special effect agent of control rice blast.Have preventive and therapeutic action to rice blast, by each site absorption of paddy rice, and can be accumulated to leaf portion tissue, thus play drug effect, resistance of rainwater washing against also doublely can control plant hopper.
Own azoles alcohol, English name: hexaconazole, CAS:79983-71-4.Belong to triazole bactericidal agent, sterol demethylation inhibitors, the disease caused fungi especially Basidiomycota and Ascomycota has protection and the therapeutic action of broad spectrum activity.The biosynthesis of the cell membrane important composition composition ergosterol of destruction and prevention germ, causes cell membrane not formed, and makes germ dead.There is interior suction, protection and therapeutic activity.
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 Isoprothiolane and the composite agricultural chemicals suspension agent of own azoles alcohol.Be achieved especially by following technical proposals:
Isoprothiolane and the composite agricultural chemicals suspension agent of own azoles alcohol, comprise the raw material of following weight percentage: Isoprothiolane 25-35%; Own azoles alcohol 3-7%.
Isoprothiolane and the composite agricultural chemicals suspension agent of own azoles alcohol, be made up of following materials by weight percentage: Isoprothiolane 25-35%; Own azoles alcohol 3-7%; Surfactant 5-9%; Ethylene glycol 5-7%; Attapulgite 0.05-0.15%; Cetanol 0.1-0.3%; Acetic acid chloroethene pyridine 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: (C2H4O) nC27H24O.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.
Isoprothiolane of the present invention and the composite agricultural chemicals suspension agent of own azoles alcohol 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, Isoprothiolane, own azoles alcohol, surfactant, ethylene glycol, attapulgite, cetanol, the pyridine of acetic acid chloroethene 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.
Isoprothiolane of the present invention and the composite agricultural chemicals suspension agent of own azoles alcohol have higher suspension rate, stable during long-term storage.Have strong Uptake and translocation effect, medicine can by each site absorption of paddy rice, and be accumulated to leaf portion tissue, and after usual dispenser 2-3 days can take effect, and shows as that rice leaf is obviously turned green, scab reduces, and the lasting period can reach about 15 days, and protecting effect of leaves is remarkable.While controlling disease, stimulate root growth, accelerate transplanting rice and turn green; The use of fringe phase can promote photosynthesis, Delaying Leaf-Senescence, strengthens plant resistance, particularly can regulate spike of rice kernel grouting, improves ripening rate and thousand kernel weight, increase yield, and can improve rice quality.
Embodiment
Embodiment 1
(1) according to formula, Isoprothiolane, own azoles alcohol, surfactant, ethylene glycol, attapulgite, cetanol, the pyridine of acetic acid chloroethene 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 2.5 μm.
