Abstract
A micropowder coating agent for seeds contains insecticide, fungicide, film-forming agent, emulsifier, disperser, wetting agent, growth regulator and kaolin micropowder. Said insecticide is organophosphorus. Its advantages are low cost and high and stable performance.
Description
The present invention relates to a kind of coating agent for seed, relate in particular to a kind of micropowder coating agent for seeds.
The various coating agent for seed of production and sales in the market (being called for short kind of a clothing agent) mostly are suspending agent type.Plant the clothing agent and serve as theme, be equipped with auxiliary agents such as bactericide, film forming agent, plant growth regulator, wetting agent and make with insecticide.Plant the clothing agent to crops prevention and elimination of disease and pests in seedling stage, promotion full stand and healthy seedling etc. has all played certain effect.But, because the insecticide in the agent of suspending agent type kind clothing is that main cost is higher with carbofuran etc., increased peasant's production cost, influenced it in wider applying.In the insecticide, the organic phosphor series pesticide has stable and obvious effects really to the control underground pests, and with low cost, but being applied to becomes suspending agent in kind of the clothing agent, and wherein water content is about 80%, and effective ingredient is very easily decomposed, do not reach standard-required, the pest control effect descends.As seen reducing kind of clothing agent cost and improving kind of a clothing agent effect is a pair of contradiction.
The object of the present invention is to provide stable, the tangible micropowder coating agent for seeds of a kind of cheap, insecticidal effect.
Technical program of the present invention lies in adopting this all clothing agent of a kind of micropowder coating agent for seeds to be made up of insecticide, bactericide, film forming agent, emulsifier, dispersant, wetting agent, plant growth regulator and kaolin micro mist, described insecticide is an organic phosphor.
Described each component effective ingredient proportioning is (percentage by weight):
Organic phosphor: 6-16%
Bactericide: 1.5-3% (triazolone) or 40-50% (tmtd or carbendazim)
Film forming agent: 2-6%
Emulsifier: 0.5-2.5%
Dispersant: 0.5-2.5%
Wetting agent: 1-4%
Plant growth regulator: 0.5-5%
The kaolin micro mist: all the other.
Described organic phosphor can be Isofenphos methyl, thimet or parathion-methyl.
Described film forming agent is the mixture of sodium carboxymethylcellulose, both one of sodium hydroxyethyl cellulose or both mixtures or both one or both mixtures and xanthan gum.Described bactericide is: triazolone, tmtd, carbendazim etc.
The micro powder granule of described kaolin micro mist has granularity more than 90% less than 4 microns.
The content of each component of the kind clothing agent that is used for wheat that meets technical solution of the present invention is for (percentage by weight):
Organic phosphor: 10%
Triazolone (bactericide): 3%
Film forming agent: 4%
White carbon (dispersant): 0.5%
2201 emulsifier: 1%
Draw back powder (wetting agent): 2%
Sodium-para-nitrophenolate (plant growth regulation): 0.5%
The kaolin micro mist: all the other.
The content of each component of the kind clothing agent that is used for corn that meets technical solution of the present invention is for (percentage by weight):
Organic phosphor: 8%
Tmtd (bactericide): 50%
Film forming agent: 3%
White carbon (dispersant): 1%
2201 emulsifier: 2.2%
Draw back powder (wetting agent): 1%
Potassium dihydrogen phosphate (plant growth regulator): 1%
The kaolin micro mist: all the other.
Each components contents that meets the kind clothing agent that is used for cotton of technical solution of the present invention is (percentage by weight):
Organic phosphor: 14%
Carbendazim (bactericide): 45%
Film forming agent: 5%
White carbon (dispersant): 2%
0204C (emulsifier): 0.7%
Draw back powder (wetting agent): 3.6%
Potassium dihydrogen phosphate (plant growth regulator): 2.5%
The kaolin micro mist: all the other.
Because the insecticide of this micro powder type kind clothing agent is served as theme with organic phosphor, the price of organic phosphor is well below the price of insecticides such as the employed carbofuran of suspending agent type kind clothing agent, thereby make the agent of micro powder type kind clothing possess the higher market competitiveness, help kind of clothing agent applying on a large scale in agricultural production, promote the development of agricultural production.Under the micro powder type kind clothing agent normality is the dry powder shape, and packing, transportation, storage etc. are convenient, and expense is also low.The agent of micro powder type kind clothing is compared with the agent of floating type kind clothing, also has few, the easy to use advantage of consumption.During use, only need to mix with water by a certain percentage to get final product, usage amount only is that sixth is arrived in 1/10th of floating type kind clothing agent.The defective of unstable properties that the application of organic phosphor in the agent of micro powder type kind clothing also solved it when using in the agent of floating type kind clothing.In addition, adopt these several water-soluble binders of sodium carboxymethylcellulose, sodium hydroxyethyl cellulose and xanthan gum as film forming agent among the present invention, make film forming layer have network structure, film forming is even, has guaranteed to plant the premium properties of clothing agent.
The production method of micro powder type kind clothing of the present invention agent is as follows, at first film forming agent, kaolin micro mist, dispersant, emulsifier, wetting agent are prepared by a certain percentage and (generally plant the clothing agent when actual production, also should add warning colouration, the normal basic rhodamine that adds 2.5-5%) puts into batch mixer, make it abundant mixing, by a certain percentage effective ingredients such as insecticide, bactericide, plant growth regulator are added then, grind after mixing once more, be ground to material particles more than 90% and below 4 μ m, can pack and become finished product.
During use, only need add water according to a certain percentage, liquid medicine is than being (1: 4-5), stir 15 minutes (or leaving standstill after stirring) and make it become suspending agent, can carry out seed pelleting in the ratio of agent kind than 1: 50.
Following table be the clothing agent of this micro powder type kind and water in 1: the ratio of 4-5 stirs the technical indicator of the suspending agent of making after 15 minutes:
| Viscosity | ????300-600Mpa.S |
| PH value | ????6.8-7.2 |
| Centrifugal degree of fixation | ＜6% (elutriation goes out volume) |
| Film formation time | ????＜10min |
| The seed expulsion rate | ????≤0.5％ |
| Coating thickness | ????4-6μm |
| Cover kind of a clothing rate | ????96％ |
As can be seen from the above table, during use, this kind clothing agent viscosity and pH value are moderate, and degree of fixation is better, and film formation time is short, does not need Exposure to Sunlight, and the seed expulsion rate is lower, and coating thickness is moderate, and kind of example is good in covering.
