Abstract

The invention relates to a thiobencarb granule. The thiobencarb granule comprises 0.01%-20% of thiobencarb, 30%-60% of carriers, 0.5 %-3% of dispersants, 0.1%-2% of controlled release agents, 1%-6% of disintegrating agents, 0.1%-5% of binders, 0.1%-0.5% of coating agents, 10%-50% of fertilizers, the balance being fillers. The thiobencarb granule is advantaged by controlled-release function, long efficacy duration and good effects.

Description

The thiobencarb granule
Technical field
The invention belongs to technical field of pesticide, relate to a kind of thiobencarb granule.
Background technology
Thiobencarb has another name called the barnyard grass peace, english common name: Thiobencarb, chemical name: the methyl S-[(4-chloro-phenyl-)] and the diethyl thiocarbamate, molecular formula: C 12H 16ClNOS, structural formula:
Figure 844204DEST_PATH_IMAGE001
Thiobencarb belongs to amino formate selectivity inner sucting conduction type soil processing herbicide, can be absorbed by the root of weeds and young shoot, and particularly young shoot is transferred in the plant materials after absorbing, and vegetative point is had very strong restraining effect.Thiobencarb hinders α-Dian Fenmei and protein synthesis, and the mitotic division of vegetable cell is also had the strongly inhibited effect, thereby causes the weed seed and the weeds at the initial stage of sprouting that sprout withered.Can be rapidly by adsorption by soil, thus little with the leaching of moisture, generally be distributed in soil layer 2 centimeters.The adsorption of soil has reduced the loss that is caused by evaporation and photodissociation.Transformation period in soil is 2-3 week under the ventilation good condition, and anaerobic condition is next to be the 6-8 month.Can be by soil microbial degradation, the dechlorination thiobencarb that is formed by soil microorganisms under the anaerobic condition can suppress paddy growth consumingly.
The inventor furthers investigate thiobencarb, and it is prepared into granule, is used for rice terrace and prevents and kill off annual grassy weeds.
Dogstail sublimed preparation granule and granule medicine fertilizer are not reported at present as yet.
Summary of the invention
Technical problem to be solved: the present invention is directed to the prior art deficiency provides a kind of thiobencarb to be combined with the carrier science and the granule developed, give full play to the weeding activity of thiobencarb, in agriculture production, use the fertilizer granules applied once to apply fertilizer and can effectively prevent and kill off the rice terrace annual grassy weeds, equally thiobencarb is processed into granule and spreads fertilizer over the fields also and can reduce medication and human cost.
Technical scheme of the present invention: a kind of thiobencarb granule, activeconstituents is thiobencarb, formed by following components in weight percentage: thiobencarb 0.01%-20%, carrier 30 as one kind %~60%, dispersion agent 0.5%~3%, sustained release dosage 0.1%~2%, disintegrating agent 1%~6%, binding agent 0.1%~5%, coating agent 0.1%~0.5%, fertilizer 10%~50%, all the other are filler.
Described carrier is quartz sand or fertilizer.
Described dispersion agent is alkylphenol polyoxyethylene formaldehyde condensation products, sulfonated lignin, polycarboxylate, naphthalenesulfonate formaldehyde condensation compound, to one or more combination in the methoxyl group fatty acyl amido Phenylsulfonic acid.
Described sustained release dosage is a kind of in polyvinyl alcohol, the gum arabic.
Described disintegrating agent is the one or more combination in sodium sulfate, urea, sodium starch glycolate, starch, yellow soda ash, ammonium sulfate, sodium-chlor, calcium chloride, the wilkinite.
Described binding agent is one or more the combination in polyoxyethylene glycol, carboxymethyl cellulose, the polyvinyl alcohol.
Described filler is the one or more combination in kaolin, diatomite, light calcium carbonate, white carbon black, attapulgite, wilkinite, starch, the stone flour.
Thiobencarb granule of the present invention is applicable to prevents and kill off the rice terrace annual grassy weeds.
Thiobencarb granule of the present invention has the following advantages:
(1) uses conveniently.Need not to adopt apparatus, directly use and spread fertilizer over the fields.
(2) safety, environmental protection.Do not add materials such as toluene class, DMF, acetone of inflammable and explosive and environmental pollution etc., ethanol, safety non-pollution in production, transportation, storage, the use does not have dust during production, not drift during use.
(3) excellent.Granule with slowly-releasing effect, the drug effect lasting period is long.
(4) cost is low.Product technology is simple, can produce finished product by material stirring → granulation → drying.Do not add high price supplies such as solvent, emulsifying agent, dispersion agent, wetting agent.
Embodiment
Preparation method of the present invention: with thiobencarb 0.01%-20%, carrier 30 as one kind %~60%, dispersion agent 0.5%~3%, sustained release dosage 0.1%~2%, disintegrating agent 1%~6%, binding agent 0.1%~5%, coating agent 0.1%~0.5%, fertilizer 10%~50%, surplus filler mix in airtight compounding kettle, adopt the granulation of coating method, after screening, drying, check, namely obtain required thiobencarb granule.The powder sieving thing is back to compounding kettle after crushed to be mixed again, unacceptable product is back to compounding kettle after the check analysis reason mixes again, mix and adopt the method for fractional steps, the lower starting material of component concentration elder generation's blending dispersion auxiliary agent or filler again with other mixing of materials, to guarantee the homogeneity of product content.Can make the different thiobencarb granule of active constituent content.
Embodiment 1:
In the granule gross weight, wherein: thiobencarb 0.2%, attapulgite 2%, polyvinylpyrrolidone 0.15%, Reactive blue 0.1%, quartz sand surplus.
According to the fertile preparation method of granule medicine of the present invention, above-mentioned material is mixed in airtight compounding kettle, the granulation of coating method through screening, drying, after the assay was approved, namely obtains 0.2% thiobencarb granule.
Embodiment 2:
In the granule gross weight, wherein: thiobencarb 0.02%, carrier fertilizer 30%, sustained release dosage 0.5%, binding agent 5%, coating agent 0.3%, all the other are the kaolin filler.
According to the fertile preparation method of granule medicine of the present invention, above-mentioned material is mixed in airtight compounding kettle, the granulation of coating method through screening, drying, after the assay was approved, namely obtains 0.2% thiobencarb granule.
Practical application effect of the present invention further specify below with the field efficacy example in order better to verify.The inventor experimentized in Lao Keng village, province Ren Shan town, Huidong, Guangdong Province in July, 2012.
Reagent agent and consumption:
The fertile consumption 200 gram a.i/667m of (1) 0.02% thiobencarb granule medicine 2
(2) 10% thiobencarb granule consumptions 200 gram a.i/667m 2
Contrast medicament: (3) 50% thiobencarb missible oil consumptions 200 gram a.i/667m 2
Prevent and kill off object: rice seedling throwing field annual grassy weeds.
Using method: the whole soil of rice terrace back seedling throwing field spreads fertilizer over the fields or pesticide-clay mixture spreads fertilizer over the fields.
Test-results shows (seeing Table 1): 0.02% thiobencarb granule medicine fertilizer and 10% thiobencarb granule are prevented and kill off rice terrace seedling throwing field annual grassy weeds preventive effect more than 95%, and effect is better than 50% thiobencarb missible oil, to rice safety.
