Abstract
The invention relates to a pesticide suspending agent. The pesticide suspending agent comprises the following materials in percentage by weight: 15-25% of active ester, 15-25% of tridemorph, 4-8% of butyl cellosolve, 0.05-0.15% of attapulgite, 4-8% of a surface active agent and the balance of water. The pesticide suspending agent is high in suspensibility, good in spreadability and permeability and stable in product performance, and is used for controlling multiple plant diseases on crops such as grains, vegetables, fruit frees and flowers, especially powdery mildew and rust disease.
Description
Technical field
The present invention relates to a kind of agricultural chemicals suspension agent.
Background technology
Acibenzolar, benzo (1,2,3) thiadiazoles-7-carbothioic acid-S-methyl esters, english common name: acibenzolar, is a kind of plant disease-resistant activator, suitable crop has paddy rice, wheat, vegetables, banana, tobacco etc.Under recommended dose to crop safety, without poisoning.Can prevent powdery mildew, rust, downy mildew etc.
Tridemorph, English common name: Tridemorph, No. CAS: 81412-43-3.Chemical name: 2,6-dimethyl-4-tridecyl morpholine.Tridemorph is mainly used in preventing and treating powdery mildem of cereals and sigatoka, to other fungal disease, as white, red, the brown root rot of: bamboo grows, powdery mildew, coffee eye spot; The cake disease that tealeaves is right; The electricity such as melon powdery mildew and the powdery mildew of flowers and trees have good preventive effect.
Agricultural chemicals suspension agent is the formulation of 20 century 70 development, has now become one of basic processing formulation.Suspending agent (Suspensionconcentrates, be called for short SC) claim again aqueous suspension agent, colloidal suspending agent, concentrated suspension, be under surfactant and other promoter effects, the former medicine that is insoluble to or is insoluble in water is distributed in water, form uniform and stable thick suspension system.Because its dispersion medium is water, so that suspending agent has cost is low, produce, storing and use the features such as safety, and easily mix with water, easy to use.Compared with the formulations of pesticide take organic solvent as 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 agricultural chemicals suspension agent.
Technical problem to be solved by this invention is achieved by the following technical solution:
Agricultural chemicals suspension agent, comprises the raw material of following weight percentage: Acibenzolar 15-25%; Tridemorph 15-25%.
Agricultural chemicals suspension agent, is comprised of following materials by weight percentage: Acibenzolar 15-25%; Tridemorph 15-25%; Butyl glycol ether 4-8%; Attapulgite 0.05-0.15%; Surfactant 4-8%; Surplus is water.
Described surfactant is poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate and/or α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Described surfactant, by 70-90 weight portion disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate and poly-(Oxy-1,2-ethylidene) non-ionic surface active agent composition of 10-30 weight portion α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate, English name: Sodium Lauryl Diphenyl Ether Disulfonate, No. CAS: 7575-62-4.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, CAS:64422-66-8, molecular formula: (C

α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, formerly be mainly used in suppressing corrosion and the galvano-cautery in line cutting processing, sludge in softening working groove is used as rust-inhibiting additive in the silk thread of being careful cuts production process.In prior art, there is not any technology enlightenment of this raw material being played to dispersion moistening effect for agricultural chemicals reagent.
Agricultural chemicals suspension agent easily produces a large amount of bubbles in process, may affect metering and the packing of preparation.Therefore, can in formula, add the defoamer of 0.1-0.7wt%, can certainly adopt in process of production the methods such as ultrasonic, vacuum defoamation to carry out froth breaking, and not need to add defoamer.Can also in formula, add according to actual needs mould inhibitor or pH adjusting agent.
Agricultural chemicals suspension agent of the present invention can adopt the general method in this area to be prepared, and one is ultramicro grinding method (also claiming wet grinding), and another kind is coacervation (also claiming hot melt-dispersion method).
Ultramicro grinding method:
(1) according to formula, Acibenzolar, tridemorph, butyl glycol ether, attapulgite, surfactant 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≤4 μ m.
(3) be placed in homogenizer homogeneous, make particle homogenising.
Suspension refers to that former powder of dispersion keeps the ability of suspension time length in suspension, represents with suspensibility conventionally.A good suspending agent, should have good storage stability, i.e. higher suspensibility.
Agricultural chemicals suspension agent of the present invention has higher suspension rate, and long-term stable storage, for preventing and treating especially powdery mildew, the rust of plurality of plant diseases in cereal, vegetables, fruit tree, flowers and other crops.
Embodiment
Embodiment 1
