Abstract
A seed treating agent in the form of superfine particles (3-16 microns) is prepared from 6 main components including triadimefon, thiram, carboxymethyl cellulose, etc and 8 secondary components including hydroxyethyl cellulose, emtrol, EDTA, etc through pulverizing and proportional mixing. Its advantages are slow release, less dosage and low cost.
Description
The present invention relates to seed treatment, be specially a kind of superfine powder seed treating agent of solid dosage forms seed treatment.
At present, the seed treatment of China divides two classes, and the one, the kind clothing agent of suspending agent type, another kind of is that common wettable powder or liquid preparation are directly used as seed dressing or increased some and be stained with knot agent seed dressing and use.The agent of suspending agent type kind clothing, safety, seed dressing is convenient and safe, have a slow releasing function, a drug can be kept 40-60 days drug effect and not only can diseases prevention but also can insect protected, but the big freight volume of the low volume of concentration increases, it is little not reduce the dosage usable floor area, use cost is afraid of the storehouse that low tempertaure storage need be incubated than higher, and cryogenic conditions influences coating effect.And the second class seed treatment, dosage is big, the expulsion rate height, and contaminated environment, medication is dangerous.External seed treatment divides three classes, and the one, the agent of suspending agent type kind clothing, the 2nd, liquid dosage form seed treatment, the 3rd, the seed treatment of solid dosage forms.The agent of suspending agent type kind clothing accounts for about 50%.European countries have certain solid dosage forms seed treatment to use, and the U.S. is suspending agent or liquid dosage form substantially.Japan, the seed treatment of using on the paddy rice is a dry powder, the major part that vegetables are used is the agent of suspending agent type kind clothing.The objective of the invention is, in safety, it is convenient and simple to dress seed, and when having slow releasing function, improves valid density, the usage amount that reduces agricultural chemicals reduces environmental pollution, increase usable floor area, reduce drug cost, reduce freight volume and cost of transportation, make seed treatment not be afraid of low tempertaure storage, reduce and store cost.Have high concentration, high activity, low consumption, low cost, be convenient to packing, transportation, storage, both be suitable for grouping of the world economy, mechanization, seed treatment in enormous quantities, also suitable seed dry method or wet method dressing in a small amount.
Kind clothing agent general in the current production of China is the colloid formulation, the ultrafine powder seed treatment with colloid kind clothing agent compared three significant advantages: the first, changed kind clothing agent formulation.The agent of colloid kind clothing is liquid suspension emulsion or colloidal suspending agent, and the agent of ultrafine powder kind clothing is the ultra-fine powder of solid.The change of formulation brings a series of convenience for packing, transportation, storage, the use of product.The second, ultra-fineization, high vigor.Ultrafine powder kind clothing agent powder diameter is at micron order＜3-16 micron, the result of ultra-fineization, and the functioning efficiency of active component improves greatly, and under the same dose situation, pesticide effectiveness improves more than 1.8 times.The 3rd, high concentration, low consumption, low cost.The active ingredient of ultrafine powder kind clothing agent is 50-65%, consumption is sixth to ten/one of colloid kind clothing agent, this is just when improving the level of resources utilization, environmental pollution and residue of pesticide have significantly been reduced, under the suitable situation of result of use, cost reduces by 1/2nd to 2/5ths.With the wheat is example, and it is 1 that pesticide-seeds ratio is used in the agent of colloid kind clothing: 50-60, and about 0.1 yuan of seed pelleting cost per jin, it is 1 that pesticide-seeds ratio is used in the agent of ultrafine powder kind clothing: 500-600, only 0.05 yuan of seed pelleting cost per jin.
Fig. 1 is a process of the present invention.
Below in conjunction with accompanying drawing in detail most preferred embodiment of the present invention is described in detail: major ingredient is triazolone 9-13, tmtd 35-45, carboxymethyl cellulose 8-15, polyoxyethylene 3-5, polyethylene glycol 2-3 neopelex 3-5, six components are dry powder after pulverizing mixing, and its diameter is the 3-16 micron.Still can add appropriate amount talcum branch in the auxiliary material, reach absolutely.Auxiliary material is hydroxyethylcellulose 0.5-1.5, fatty alcohol 1-2, zinc sulphate 2-3, EDTA1-2, manganese sulphate 2-4, borax 0.5-1.5, citric acid 2-5, white carbon 2-5.Raw material are pressed drop into the powder machine that mixes after the accurate weighing of recipe ingredient, enter the sifted branch after fully mixing, remove impurity.Pulverize through cracker if any larger particles, enter the ultra-fine grinding operation in the lump with screenings and carry out ultra-fineization processing, institute goes out superfine powder and enters second drum mixer after metering and fully mix, and sends into the packing machine quantitative package at last, the vanning warehouse-in.
Example 1: major ingredient is triazolone 9, tmtd 35, carboxymethyl cellulose 8, polyoxyethylene 3, polyethylene glycol 2, neopelex 3; Auxiliary material is hydroxyethylcellulose 0.5, fatty alcohol 1, zinc sulphate 2, EDTA1, manganese sulphate 2, borax 0.5, citric acid 2, white carbon 2,31, ten five components of fossil meal through pulverizing after mixing is dry powder, and its diameter is 3 microns.Get 1 part of dry powder of the present invention, add 4 parts of water stirrings and make suspending agent, add in wheat seed at 1: 100 by the pharmacopoeia weight ratio, stirring gets final product again.
Example 2: major ingredient is triazolone 13, tmtd 45, carboxymethyl cellulose 15, polyoxyethylene 5, polyethylene glycol 3, neopelex 5; Auxiliary material is hydroxyethylcellulose 1.5, fatty alcohol 2, zinc sulphate 3, EDTA2, manganese sulphate 4, borax 1.5, citric acid 5 white carbons 5.14 components are dry powder after pulverizing mixing, and its diameter is 16 microns.Get 1 part of dry powder of the present invention, add 5 parts of water stirrings and make suspending agent, add in wheat seed at 1: 100 by the pharmacopoeia weight ratio, stirring gets final product again.
Example 3: major ingredient is triazolone 10, tmtd 42, carboxymethyl cellulose 13, polyoxyethylene 4, polyethylene glycol 2.5, neopelex 4, fossil meal 24.5.Seven components are dry powder after pulverizing mixing, and its diameter is 14 microns.Get 1 part of dry powder of the present invention, add 4.5 parts of water stirrings and make suspending agent, add in wheat seed at 1: 100 by the pharmacopoeia weight ratio, stirring gets final product again.The present invention claims the agent of ultrafine powder kind clothing again, the invention solves three technical problems.
One, it is ultra-fine that the formulation of superfine powder kind clothing agent requires product cut size.Because have only superfine powder just to have high-specific surface area, the characteristic of high surface energy and high absorption, and these characteristics have exactly been given the various active components of kind clothing agent have the high activity vigor under low dosages, make this product have cost low, consumption is few, acts on tangible advantage.This is that common mechanical crushing is difficult to realize.This equipment utilization high velocity air is a carrier, and the speed that material is accelerated to 1000m/s clashes mutually, realizes the purpose of pulverizing.
Two, one of characteristic of this product is that the size distribution band of requirement powder is narrow, and only in the certain particle scope, the advantage of formulation and effect are just more obvious, and the automatic grading plant of airslide disintegrating mill is by having satisfied above-mentioned requirements to the adjusting of sorter parameter.
Three, one of main component of this product---film forming agent is a kind of macromolecular material of growing carbochain, and flexible under the normal temperature, softening point are about 54 ℃.All there is the intensification phenomenon in general dry pulverization process, can't realize ultra-fineization processing to this composition, when two strands of gas thing mixtures clash mutually in the Jet Mill, adiabatic expansion principle according to gas, can produce-40 ℃ of low temperature, reach the pulverizing requirement of film forming agent fully, realized the ultra-fine grinding of film forming agent.Belong to domestic initiation, still do not have similar manufacturer production.
Superfine powder kind clothing agent consumption is few, and pesticide-seeds ratio 1 on wheat: 500--600 only is 1/8th of colloid type kind clothing agent, is 1 on corn: 250--300 only is the sixth of colloid type kind clothing agent.Compare with the agent of colloid kind clothing, though the unit price of superfine powder kind clothing agent is higher, it uses the mu cost but is 1/2nd to 1/3rd (seeing table 1 for details) of colloid.
