The invention relates to a weed-killing suspending agent obtained by compounding sulcotrione and atrazine. The weed-killing suspending agent comprises the following materials in percentage by weight: 15-25% of sulcotrione, 15-25% of atrazine, 5-9% of a surface active agent, 5-7% of glycerinum, 0.05-0.15% of hydroxypropyl cellulose, 0.1-0.3% of dimethicone, 0.01-0.03% of sodium benzoate and the balance of water. The weed-killing suspending agent has the advantages that the suspensibility is high, the long-time storage is stable, the weed control spectrum is expanded, the application time is reduced, the control cost is reduced, the resistance of weeds is reduced, the safety of crops is good and the safety requirement for pesticide preparations is met.
Description
Technical field
The present invention relates to the weeding suspending agent of a kind of sulphur humulone and atrazine.
Background technology
Sulphur humulone, English name: Sulcotrione, name of product 2-(the chloro-4-methylsulfonyl of 2-) benzoyl-1, hydroresorcinol, CAS accession number: 99105-77-8.Sulphur humulone (sulcotrione) is p-hydroxybenzene keto ester dual oxide enzyme (HPPD) inhibitor, can be absorbed by the root of plant and cauline leaf, by suppressing the synthetic of p-hydroxybenzene keto ester dual oxide enzyme, cause the accumulation of tyrosine, the biosynthesis of plastoquinone and vitamin e is obstructed, and then have influence on the biosynthesis of carotenoid, dead after the albefaction of weeds cauline leaf.After maize seedling, use sulphur humulone, nitro sulphur humulone is met low temperature after excessive or dispenser can make corn be injured, and leaf look yellow is or white, generally within 7-10 days, restore normal growth.
Atrazine, English common name: atrazine; The chloro-4-diethylin-6-of chemical name: 2-isopropylamine base-1,3,5-triazines, CAS accession number: 1912-24-9.Be before interior suction selectivity seedling, seedling rear enclosed weed killer herbicide.Root absorption is main, and cauline leaf absorbs seldom.The same Simanex of herbicide effect and selectivity, easily by rainwater drip washing to soil compared with deep layer, also effective to some dark root grass, but easily produce poisoning.Lasting period is also longer.
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 the weeding suspending agent of a kind of sulphur humulone and atrazine.Specifically by following technical proposals, be achieved:
The weeding suspending agent of sulphur humulone and atrazine, comprises the raw material of following weight percentage: sulphur humulone 15-25%; Atrazine 15-25%.
The weeding suspending agent of sulphur humulone and atrazine, is comprised of following materials by weight percentage: sulphur humulone 15-25%; Atrazine 15-25%; Surfactant 5-9%; Glycerine 5-7%; Carboxy-propyl cellulose 0.05-0.15%; Dimethicone 0.1-0.3%; Sodium Benzoate 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 comprised 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: (C

24o.Succinate sodium 2-ethylhexyl, claims again: Aerosol OT, No. CAS: 577-11-7.
Can also in formula, add pH adjusting agent according to actual needs.
The weeding suspending agent of sulphur humulone of the present invention and atrazine can adopt the general method in this area to be prepared, and a kind of is ultramicro grinding method, and another kind is coacervation.
Concrete, described ultramicro grinding method:
(1) according to formula, sulphur humulone, atrazine, surfactant, glycerine, carboxy-propyl cellulose, dimethicone, Sodium Benzoate 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 weeding suspending agent of sulphur humulone of the present invention and atrazine has higher suspension rate, and long-term stable storage expands control of weeds spectrum, reduces spraying times, reduce cost accounting, slow down the generation of Weed Resistance, good to crop safety, meet the security requirement of pesticidal preparations.
Embodiment
Embodiment 1
(1) according to formula, sulphur humulone, atrazine, surfactant, glycerine, carboxy-propyl cellulose, dimethicone, Sodium Benzoate 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: the weeding suspending agent formula table unit of sulphur humulone and atrazine: kilogram
