Abstract
The invention relates to a pesticide suspending agent compounded from hexaflumuron and cypermethrin. The pesticide suspending agent consists of the following raw materials in percentage by weight: 0.5-1.5% of hexaflumuron, 3-5% of cypermethrin, 4-8% of surfactant, 5-7% of propylene glycol, 0.05-0.15% of carboxyl propyl cellulose, 0.1-0.3% of tributyl phosphate, 0.01-0.03% of methylparaben and the balance of water. The pesticide suspending agent is high in suspension rate and is stable after being preserved for a long time, and tests show that the pesticide suspending agent has an excellent fly killing effect.
Description
Technical field
The present invention relates to a kind of HEXAFLUMURON and cypermethrin compounded agricultural chemicals suspension agent.
Background technology
HEXAFLUMURON, English name: Hexaflumuron, No. CAS: 86479-06-3.HEXAFLUMURON is novel acylureas insecticides; except having other acyl group ureas desinsection features; insecticidal spectrum is wider, especially the insect of genus heliothis is had to special efficacy, respond well to noctuidae pests such as gypsymoth, tent caterpillar, dysychira abietis, sweet Lay noctuid, the real noctuids of paddy.
Cypermethrin, English name: Cypermethrin., CAS:86753-92-6.
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 HEXAFLUMURON and cypermethrin compounded agricultural chemicals suspension agent.Specifically be achieved by following technical proposals:
HEXAFLUMURON and cypermethrin compounded agricultural chemicals suspension agent, comprise the raw material of following weight percentage: HEXAFLUMURON 0.5-1.5%; Cypermethrin 3-5%.
HEXAFLUMURON and cypermethrin compounded agricultural chemicals suspension agent, be made up of following materials by weight percentage: HEXAFLUMURON 0.5-1.5%; Cypermethrin 3-5%; Surfactant 4-8%; Propane diols 5-7%; Carboxy-propyl cellulose 0.05-0.15%; Tributyl phosphate 0.1-0.3%; Methyl hydroxybenzoate 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 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.
HEXAFLUMURON of the present invention and cypermethrin compounded agricultural chemicals suspension agent 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, HEXAFLUMURON, cypermethrin, surfactant, propane diols, carboxy-propyl cellulose, tributyl phosphate, methyl hydroxybenzoate 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.
HEXAFLUMURON of the present invention and cypermethrin compounded agricultural chemicals suspension agent have higher suspension rate, long-term stable storage.Evidence, the present invention has excellent effect of killing flies.
Embodiment
Embodiment 1
(1) according to formula, HEXAFLUMURON, cypermethrin, surfactant, propane diols, carboxy-propyl cellulose, tributyl phosphate, methyl hydroxybenzoate 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.
The suspending agent making, the liquid of outward appearance thickness homogeneous phase, measures through Ma Erwen laser fineness gage, and its average grain diameter (D50) is 3 μ m.
Table 1: HEXAFLUMURON and cypermethrin compounded agricultural chemicals suspension agent formula table unit: kilogram
Embodiment 2
Take raw material by corresponding embodiment 2 data of table 1, be prepared by the method for embodiment 1.The suspending agent making, average grain diameter (D50) is 3 μ m.
Embodiment 3
Take raw material by corresponding embodiment 3 data of table 1, be prepared by the method for embodiment 1.The suspending agent making, average grain diameter (D50) is 3 μ m.
High temperature storage 14 days under 14 days, 54 ℃ ± 2 ℃ conditions of room temperature storage respectively, adopts " GB/T14825-2006 agricultural-chemical suspension rate assay method " to survey suspensibility, and concrete data see the following form 2.In the time of suspensibility >85%, think that this product is certified products.
Table 2: agricultural-chemical suspension rate determination data list position: %
| ? | Embodiment 1 | Embodiment 2 | Embodiment 3 |
