Description
Technical field
The present invention relates to a kind of cyhalofop-butyl oil-suspending agent.
Background technology
Cyhalofop-butyl, English name: cyhalofop-butyl, (R)-2-[4 (4-cyano group-2-fluorophenoxy) phenoxy group]-butyl propionate.Belong to aryloxyphenoxypropionic class weed killer herbicide.Paddy field selective herbicide, can only do cauline leaf process, and bud pre-treatment is invalid, mainly prevents and kill off barnyard grass, the grassy weeds such as moleplant seed.
Oil-suspending agent, is called for short oil suspending agent, refers to that one or more pesticide active ingredients (wherein having at least a kind of is 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 without dilution, can 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 cyhalofop-butyl oil-suspending agent.Be achieved especially by following technical proposals:
Cyhalofop-butyl oil-suspending agent, comprises the raw material of following weight percentage: cyhalofop-butyl 15-25%; Surplus is corn oil.
Cyhalofop-butyl oil-suspending agent, is made up of following materials by weight percentage: cyhalofop-butyl 15-25%; Surfactant 7-9%; Diethyl malonate 2-4%; Fume colloidal silica 1-3%; Dimethicone 0.1-0.3%; Sodium Benzoate 0.2-0.4%; Surplus is corn 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, is made up of 30-70 weight portion cumene sodium sulfonate and poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent 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.
Cyhalofop-butyl oil-suspending agent of the present invention can adopt the general method in this area to be prepared, as:
(1) in mixing kettle, add cyhalofop-butyl, surfactant, diethyl malonate, fume colloidal silica, dimethicone, Sodium Benzoate and corn oil, be uniformly mixed;
(2) be placed in sand mill and carry out ultramicro grinding, controlling average grain diameter is 3 μm;
(3) check, qualified rear packing.
Cyhalofop-butyl oil-suspending agent of the present invention has higher suspension rate, stable during long-term storage.The present invention is mainly used in preventing and kill off important grassy weed, efficient to moleplant seed, have certain preventive effect to low age barnyard grass, also can prevent and kill off, lady's-grass, Paspalum distichum, green foxtail, eleusine indica, amur foxtail etc.
Embodiment
Embodiment 1
(1) each raw material is taken by table 1 corresponding embodiment 1 data;
(2) in mixing kettle, add cyhalofop-butyl, surfactant, diethyl malonate, fume colloidal silica, dimethicone, Sodium Benzoate and corn oil, be uniformly mixed;
(3) be placed in sand mill and carry out ultramicro grinding, controlling average grain diameter is 3 μm;

Table 1: cyhalofop-butyl oil-suspending agent formula table unit: kilogram
Embodiment 2
Take raw material by table 1 corresponding embodiment 2 data, be prepared by the method for embodiment 1.
Embodiment 3
Take raw material by table 1 corresponding embodiment 3 data, be prepared by the method for embodiment 1.
Test case
High temperature storage 14 days under room temperature storage 14 days, 54 DEG C ± 2 DEG C conditions respectively, adopt " GB/T14825-2006 agricultural-chemical suspension rate assay method " to survey suspensibility, concrete data see the following form 2.As suspensibility >85%, then think that this product is certified products.
Table 2: agricultural-chemical suspension rate determination data list position: %
| Embodiment 1 | Embodiment 2 | Embodiment 3 | |
| Room temperature storage is after 14 days | 98.9 | 98.2 | 97.8 |
| High temperature storage is after 14 days | 98.2 | 97.4 | 96.9 |
Suspension refers to that former powder of dispersion keeps the ability of suspension time length in suspension, usually represents with suspensibility.A good suspending agent, should have good storage stability, namely higher suspensibility.
Cyhalofop-butyl oil-suspending agent of the present invention, suspensibility is high, plate-out ability and good penetrability, and properties of product are stablized.The present invention is mainly used in preventing and kill off important grassy weed, efficient to moleplant seed, have certain preventive effect to low age barnyard grass, also can prevent and kill off, lady's-grass, Paspalum distichum, green foxtail, eleusine indica, amur foxtail etc.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent is mainly used in suppressing the corrosion in linear cutter and galvano-cautery, sludge in softening working groove, is used as rust-inhibiting additive in low-speed WEDM production process.In prior art, do not have and this raw material is used for any technology enlightenment that agricultural chemicals reagent plays dispersion moistening effect.In the present invention, poly-(the Oxy-1 of α-[three (phenyl methyl) phenyl]-ω-hydroxyl being originally used for rust-inhibiting additive in a creative way, 2-ethylidene) non-ionic surface active agent is diverted in insecticidal suspending agent, plays dispersion moistening effect.Especially, cumene sodium sulfonate and α-[three (phenyl methyl) phenyl]-ω-hydroxyl are gathered (Oxy-1,2-ethylidene) non-ionic surface active agent composite, Synergistic, effectively improves suspensibility.
