Abstract
The present invention relates to a micro-powdery coating agent for seeds, which comprises a pesticide, a germicide, a film-forming agent, an emulsifying agent, a dispersing agent, a wetting agent, a plant growth regulator and the micro powder of kaoline, wherein the pesticide is an organophosphorus compound. The coating agent for seeds has the advantages of low cost and stable and obvious performance, is convenient to popularize in a large scale in industrial production, and is favorable for rural economic development.
Description
Technical field
The present invention relates to a kind of coating agent for seed, relate in particular to a kind of micropowder coating agent for seeds.
Background technology
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, the promotion seedling is complete, Miao Zhuan etc. all played certain effect.But because the insecticide in the agent of suspending agent type kind clothing is based on carbofuran etc., cost is higher, has increased peasant's production cost, has 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 active 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.
Summary of the invention
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 a kind of micropowder coating agent for seeds, this micropowder coating agent for seeds is made up of organophosphorus insecticide, bactericide, film forming agent, emulsifier, dispersant, wetting agent, plant growth regulator and kaolin micro mist, and the weight proportion of each component is:
Organophosphorus insecticide: 6-16%
Bactericide: 1.5-50%
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,
Wherein organophosphorus insecticide is Isofenphos methyl, thimet or parathion-methyl.
Described bactericide is tmtd or carbendazim, and weight percentage is: 40-50%.
Described bactericide is a triazolone, and its weight percentage is: 1.5-3%.
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.
The micro powder granule of described kaolin micro mist has granularity more than 90% less than 4 microns.
The weight proportion of above-mentioned each component is:
Isofenphos methyl: 10%
Triazolone: 3%
Film forming agent: 4%
White carbon: 0.5%
2201 emulsifier: 1%
Draw back powder: 2%
Sodium-para-nitrophenolate: 0.5%
The kaolin micro mist: all the other.
The weight proportion of described each component is:
Parathion-methyl: 8%
Tmtd: 50%
Film forming agent: 3%
White carbon: 1%
2201 emulsifier: 2.2%
Draw back powder: 1%
Potassium dihydrogen phosphate: 1%
The kaolin micro mist: all the other.
The weight proportion of described each component is:
Thimet: 14%
Carbendazim: 45%
Film forming agent: 5%
White carbon: 2%
0204C： 0.7％
Draw back powder: 1%
Potassium dihydrogen phosphate: 2.5%
The kaolin micro mist: all the other.
Because the insecticide of micropowder coating agent for seeds of the present invention 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 powder Seed Coating Agent possess the higher market competitiveness, help coating agent for seed applying on a large scale in agricultural production, promote the development of agricultural production.Micropowder coating agent for seeds is the dry powder shape under normal conditions, and packing, transportation, storage etc. are convenient, and expense is also low.Micropowder coating agent for seeds is compared with the floating type coating agent for seed, 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 1/10th of floating type coating agent for seed arrives sixth.The defective of unstable properties that the application of organic phosphor in micropowder coating agent for seeds also solved it when using in the floating type coating agent for seed.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 the premium properties of coating agent for seed.
Embodiment
Embodiment 1
It is as follows that the present invention is used for the weight percentage of each component of kind clothing agent of wheat: Isofenphos methyl 10%, and triazolone 3%, film forming agent 4%, white carbon 0.5%, 2201 emulsifier 1% draws back powder 2%, sodium-para-nitrophenolate 0.5%, kaolin micro mist 79%.
Embodiment 2
It is as follows that the present invention is used for the weight percentage of each component of kind clothing agent of corn: parathion-methyl 8%, and tmtd 50%, film forming agent 3%, white carbon 1%, 2201 emulsifier 2.2% draws back powder 1%, potassium dihydrogen phosphate 1%, kaolin micro mist 33.8%.
Embodiment 3
It is as follows that the present invention is used for the weight percentage of each component of kind clothing agent of cotton: thimet 14%, and carbendazim 45%, film forming agent 5%, white carbon 2%, 0204C emulsifier 0.7% draws back powder 1%, potassium dihydrogen phosphate 2.5%, kaolin micro mist 29.8%.
The production method of micropowder coating agent for seeds of the present invention 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 active ingredients such as organophosphorus 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, medicine be that (1: 4-5), stirring 15 minutes (or leaving standstill after the stirring), make it become suspending agent, can be that 1: 50 ratio is carried out seed pelleting in agent kind ratio with the ratio of water.
Following table be this micropowder coating agent for seeds with 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 |
| The 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 coating agent for seed 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 it is good to cover kind of clothing rate.
