Ethyl pleocidin and the composite oil-suspending agent of desinsection list
Technical field
The present invention relates to a kind of ethyl pleocidin and the composite oil-suspending agent of desinsection list.
Background technology
Ethyl pleocidin, English name: Spinetoram, works code: XDE-175, registration number: 187166-40-1187166-15-0.Be the novel pleocidin insecticides of one of being produced by Dow AgroSciences, and receive first whole world registration, it can effectively control a kind of thorny primary pest on important insect pest, the especially fruit tree on fruit tree and nut---the stupid moth of apple.
Desinsection list, chemical name: 1. thiosulfonic acid sodium base 2. dimethylamino 3. thiosulfonic acid base propane, English name: Monosultap, CAS 29547-00-0.Be the analog of artificial synthetic nereistoxin, enter and in insect bodies, be converted into rapidly nereistoxin or Dihydronereistoxin element.This medicine is acetylcholine competitive inhibitor, have stronger tag, stomach toxicity and interior suction conduction, the larva of lepidoptera pest is had to good control efficiency.
Oil-suspending agent, is called for short oil suspending agent, refers to that one or more pesticide active ingredients (wherein have at least a kind of for the former medicine of solid) form high dispersive, stable suspension system in grease dispersion medium.Oil-suspending agent is generally rear for spraying with grease dilution, also can, without dilution, do ultra low volume spraying.
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 ethyl pleocidin and the composite oil-suspending agent of desinsection list.Specifically by following technical proposals, be achieved:
Ethyl pleocidin and the composite oil-suspending agent of desinsection list, comprise the raw material of following weight percentage: ethyl pleocidin 0.5-1.5%; Desinsection list 15-25%.
Ethyl pleocidin and the composite oil-suspending agent of desinsection list, be comprised of following materials by weight percentage: ethyl pleocidin 0.5-1.5%; Desinsection list 15-25%; Surfactant 7-9%; Dibutyl adipate 2-4%; Carbomer 1-3%; Cetanol 0.1-0.3%; Propylben 0.2-0.4%; Surplus is soybean oil.
Described surfactant is poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of cumene sodium sulfonate and/or α-[three (phenyl methyl) phenyl]-ω-hydroxyl.Preferably, described surfactant, by 30-70 weight portion cumene sodium sulfonate and poly-(Oxy-1,2-ethylidene) non-ionic surface active agent composition of 30-70 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.Cumene sodium sulfonate, No. CAS: 28348-53-0.
The composite oil-suspending agent of ethyl pleocidin of the present invention and desinsection list can adopt the general method in this area to be prepared, as:
(1) in mixing kettle, add ethyl pleocidin, desinsection list, surfactant, dibutyl adipate, carbomer, cetanol, propylben and soybean oil, be uniformly mixed;
(2) be placed in sand mill and carry out ultramicro grinding, controlling average grain diameter is 3 μ m;
(3) check, qualified rear packing.
Ethyl pleocidin of the present invention and the composite oil-suspending agent of desinsection list have higher suspension rate, long-term stable storage.The present invention is applicable to prevent and treat arthropod, especially Insecta, arachnids or Nematoda.

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.
Ethyl pleocidin of the present invention and the composite oil-suspending agent of desinsection list, suspensibility is high, plate-out ability and good penetrability, properties of product are stable.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent is 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.In the present invention, in a creative way by poly-α-[three (phenyl methyl) phenyl]-ω-hydroxyl that is originally used for rust-inhibiting additive (Oxy-1,2-ethylidene) non-ionic surface active agent is diverted in insecticidal suspending agent, plays dispersion moistening effect.Especially, by composite to cumene sodium sulfonate and poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of α-[three (phenyl methyl) phenyl]-ω-hydroxyl, Synergistic, effectively improves suspensibility.
