Abstract
The invention discloses a flumetralin suspending agent type plant growth conditioning agent and a production method and aims at solving the problem that a flumetralin agent type product pollutes the environment. The flumetralin suspending agent type plant growth conditioning agent is made of the following materials: by weight, 10%-30% of flumetralin active compounds, 20%-30% of wetting dispersants, 0.5-2.05% of thickening agents, 3-5% of anti-freezing agents, and the balance dispersion media. The production method of the product comprises the steps of feeding wetting dispersants and dispersion media into a mixing kettle, feeding flumetralin active compounds, thickening agents and anti-freezing agents into the mixing kettle, stirring the materials to be even; conveying the evenly-stirred mixing materials into a shearing kettle from the mixing kettle, and stirring and grinding the mixing materials so as to obtain the agent. The flumetralin suspending agent type plant growth conditioning agent is good in chemical and physical stability, good in safety performance, and friendly to the environment, can reduce pollution of plant growth conditioning agents of the same kind to the ecology environment in the utilization process, and improves safety in the process of production and the process of storage.
Description
Technical field
The invention belongs to pesticide plant growth regulator field, particularly relate to a kind of oil-suspending agent type plant growth regulator, this formulation is the direction of domestic and international pesticides new formulation research and development, is a kind of flumetralim oil-suspending agent for coordinate plant growth.
Background technology
Local internal-suction type is efficient, low toxicity plant growth regulator for contact is held concurrently for flumetralim, at present main at Tobacco Farm for suppressing the growth of tobacco lateral bud, after tobbaco, dispenser is once, tobacco axillary bud can be suppressed to occur until results.The tobacco leaf of medicament contact full extension does not produce poisoning, can save and beat the artificial of lateral bud in a large number, and make physical maturity degree unanimously, on raising tobacco, intermediate ratio.Also can alleviate the contagion of field mosaic disease, have certain effect to prevention mosaic disease.
At present, the flumetralim product of market sale is mainly 25% flumetralim missible oil.25% flumetralim missible oil concrete operations technique following (calculating to produce 1000 kilogram of 25% flumetralim missible oil): be the former medicine of flumetralim of 98% by 255 kilograms of content, 625 kilograms of content is that the dimethylbenzene of 99.5% and the emulsifier of 20 kilograms of content 99.5% drop in formulation still successively in order and stir.Temperature, at 50 ~ 55 DEG C, stirs 1 ~ 4 hour, analyze qualified after put into finished product storage tank and pack.Due in 25% flumetralim missible oil except active ingredient flumetralim and emulsifier, also have a large amount of organic solvent---dimethylbenzene, dimethylbenzene accounts for 62.5% of gross weight.Flumetralim missible oil, while reaching coordinate plant growth object for farmland, also causes certain pollution to ecotope; In addition, because dimethylbenzene is volatile, inflammable, explosive, also bring some unsafe factors to producing, storing and transporting.
Summary of the invention
The object of this invention is to provide a kind of flumetralim oil-suspending agent type plant growth regulator, to solve the problem of environmental pollution that flumetralim missible oil dosage form product exists.
Another object of the present invention is to provide a kind of production method of flumetralim oil-suspending agent type plant growth regulator.
The technical solution adopted for the present invention to solve the technical problems is as follows:
A kind of flumetralim oil-suspending agent type plant growth regulator, be made up of the raw material of following weight percent:
The former medicine 10% ~ 30% of flumetralim,
Wetting dispersing agent 20% ~ 30%,
Thickener 0.5% ~ 2.05%,
Antifreezing agent 3% ~ 5%,
Surplus is that dispersion medium supplies 100%, and described dispersion medium is vegetable oil.
A kind of flumetralim oil-suspending agent type plant growth regulator, be preferably made up of the raw material of following weight percent:
The former medicine 20% ~ 30% of flumetralim,
Wetting dispersing agent 25% ~ 30%,
Thickener 0.5% ~ 2.05%,
Antifreezing agent 3% ~ 5%,
Surplus is dispersion medium, and described dispersion medium is vegetable oil, as soybean oil, corn oil.
In order to better realize the present invention, described wetting dispersing agent is the mixture of octadecanoic acid ester of polyethylene glycol, thermally coupled distillation columns.The mass ratio of described octadecanoic acid ester of polyethylene glycol and thermally coupled distillation columns is 1:1-1.15.Described thickener is the one in xanthans, white carbon, aluminium-magnesium silicate.Described antifreezing agent is the one in ethylene glycol or propane diols.
A production method for flumetralim oil-suspending agent type plant growth regulator, carries out following production process according to the proportioning in claim 1,
A, in mixing kettle, add wetting dispersing agent and dispersion medium, be heated to 35 ~ 40 DEG C, stir and make mixing of materials even;
B, in mixing kettle, add the former medicine of flumetralim, thickener, antifreezing agent again, stir and make mixing of materials even;
C, the mixed material stirred is proceeded to shearing still by mixing kettle, stir, material is mixed further;
D, to be squeezed in sand mill by above-mentioned material and grind, grinding is until material average grain diameter is 2 ~ 4 microns;
E, sample analysis are checked, and qualified rear packing, final products are yellow flowable suspension liquids.
In order to better realize the present invention, the mixing speed in described step C is 3000r/min.
Product of the present invention is the novel form-oil-suspending agent of flumetralim, flumetralim oil-suspending agent is the stable non-cream preparation be made up with suitable auxiliary agent of the former medicine of flumetralim, it take vegetable oil as dispersion medium, be a kind of feature of environmental protection formulation, this product chemical physical stability is good, safety is good and environmental friendliness; Reduce similar plant growth regulator in use to the pollution problem of ecotope, improve the safety in production, transporting procedures.
Prove (field control effectiveness test report is attached) through field control effectiveness test, under the prerequisite reaching the identical control efficiency of 25% flumetralim missible oil, this invention avoids the use of organic solvent.
Existing 25% flumetralim oil-suspending agent and product of the present invention 25% flumetralim missible oil are compared: the 1. domestic market demand amount about 1000 tons of current 25% flumetralim missible oil, that is, the whole nation about has 1,000 ten thousand mu of farmlands to use this plant growth regulator, and the total usage amount of organic solvent is at 625 tons; If in user's use procedure, 25% flumetralim oil-suspending agent is all used to replace 25% flumetralim missible oil, by the usage amount of minimizing 625 tons of organic solvents.Use in farmland so 25% flumetralim oil-suspending agent is substituted 25% flumetralim missible oil, it is apparent to the contribution of ecotope.2. flumetralim oil-suspending agent does not use volatile, inflammable, explosive organic solvent, so safety is good, is convenient to processing, storage and transport.
There is provided below " the pesticide field efficacy medicine test report " of being provided by weed killer herbicide new technology development popularization center of Shandong Province (test License Number: SY201000902), to further illustrate the control efficiency to controlling object of the present invention:
