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 synthesis 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.Use sulphur humulone after maize seedling, nitro sulphur humulone meets low temperature after excessive or dispenser can make corn be injured, and leaf look yellow is or white, and general 7-10 days restore normal growth.
Atrazine, English common name: atrazine; The chloro-4-diethylin of chemical name: 2--6-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.Herbicide effect and the same Simanex of selectivity, easily by rainwater drip washing to soil comparatively 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, also known as aqueous suspension agent, colloidal suspending agent, concentrated suspension, has cost low, the features such as production, storing and use safety, and easily mixes 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.Be achieved especially by following technical proposals:
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 made up 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 made up 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, also known as: Aerosol OT, No. CAS: 577-11-7.
PH adjusting agent can also be added according to actual needs in formula.
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 one 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 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 μm.
(3) be placed in homogenizer homogeneous, make particle homogenization.
The weeding suspending agent of sulphur humulone of the present invention and atrazine has higher suspension rate, stable during long-term 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 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 μm.
(3) be placed in homogenizer homogeneous, make particle homogenization.
Obtained suspending agent, the liquid of outward appearance thickness homogeneous phase, measure through Malvern laser fineness gage, its average grain diameter (D50) is 3 μm.
Table 1: the weeding suspending agent formula table unit of sulphur humulone and atrazine: kilogram
The sulphur humulone of embodiment 1 and the weeding suspending agent of atrazine, expand control of weeds spectrum, reduce spraying times, reduce cost accounting, slow down the generation of Weed Resistance, good to crop safety, meets the security requirement of pesticidal preparations.
Use in the corn 3-4 leaf phase, dosage is 0.9kg/hm
