Description
Technical field
The present invention relates to kind clothing agent and preparation method thereof, relating in particular to a kind of is floating type paddy rice seed coating agent of Main Ingredients and Appearance and preparation method thereof with Imidacloprid and Prochloraz.
Background technology:
Imidacloprid is a kind of nitro-methylene-type systemic insecticide, is the acting body of nicotinic acid acetylcholinesterase acceptor, is used to prevent and treat pierce-suck type oral cavity insect, and is effective to coleoptera, diptera and Lepidoptera.Be specially adapted to seed treatment; Prochloraz is a kind of broad spectrum agricultural bactericide, and the disease that various crop is caused by sac fungi and imperfect fungus has tangible preventive effect, also can use with most of bactericide, Insecticides (tech) ﹠ Herbicides (tech), and the better prevention effect is all arranged.Multiple diseases on field crop, fruit and vegetable, turf and the ornamental plants had treatment and eradicant action.Two kinds of medicaments use separately, and the property of medicine is single, and can not play can desinsection, effect that again can sterilization.
Summary of the invention:
For solving the problem of above existence, the invention provides a kind of suspension seed-coating agent that contains Prochloraz and preparation method thereof, it is composite that purpose is exactly to be with Imidacloprid and Prochloraz that effective ingredient is carried out, and gives full play to the advantage of the two.For realizing this purpose, the technical solution used in the present invention is:
The agent of this kind clothing is formulated by following raw materials by weight percent: Imidacloprid 2-10%, Prochloraz 0.3-5%, emulsifier 3-5%, dispersant 2-5%, film forming agent 4-8%, antifreezing agent 2-5%, thickener 0.2-3%, warning colouration 0.2-0.5%, defoamer 0.1-0.2%, water 58.3-86.2%.
Emulsifier can be calcium dodecyl benzene sulfonate (agricultural newborn 500#), styryl phenol APEO (603#), styryl phenol formaldehyde resin polyoxyethylene polyoxypropylene block type polyethers (peaceful newborn 33#), castor oil polyoxyethylene ether (By-125 and By-140), polysorbas20-40 (T-20 and T-40), styrene (or AMS) phenol formaldehyde resin APEO (peaceful newborn 700#), polyoxyethylene nonylphenol ether modified phosphate fat (phosphoric acid fat 500#), in the styrene phenol formaldehyde resin polyoxyethylene ether phosphate salt (WPJ) one or more.
Dispersant can be one or more in di-2-ethylhexylphosphine oxide naphthalene sulfonate (NNO), desugar sodium lignin sulfonate (M-9), di-2-ethylhexylphosphine oxide methyl naphthalene sulfonic acid salt (MF), the sodium lignin sulfonate (MS).
The mixture that film forming agent is made up of polyvinyl alcohol 1788, water-based benzene emulsion, Sodium Benzoate and water.Antifreezing agent can be a kind of in ethylene glycol, propane diols, the glycerine.Thickener can be one or more in acrylic acid series polymeric compounds, cellulosic derivative, aluminium-magnesium silicate, xanthans, the bentonite.Warning colouration can be a kind of in rhodamine toner, water-based rhodo, the azarin.Defoamer can be a kind of in n-octyl alcohol, the organosilicon.
The preparation method of this kind clothing agent is: at first by following percentage by weight each raw material of weighing: Imidacloprid 2-10%, Prochloraz 0.3-5%, emulsifier 3-5%, dispersant 2-5%, film forming agent 4-8%, antifreezing agent 2-5%, thickener 0.2-3%, warning colouration 0.2-0.5%, defoamer 0.1-0.2%, water 58.3-86.2%; Respectively Imidacloprid, Prochloraz, emulsifier, dispersant, film forming agent, antifreezing agent, thickener, warning colouration and water being dropped into the sand milling still then ground 1.5-2.5 hour; Add the defoamer froth breaking at last, wait to steep the discharging afterwards that disappeared, analyze qualified packing and get final product.
The agent of this kind clothing is a composite insecticidal sterilization pesticide mixture, consists of two kinds of effective ingredients of A and B.Effective ingredient A is an Imidacloprid, english common name is imidacloprid, chemical name is 1-(6-chloro-3-pyridylmethyl)-N-nitro industry imidazolidine-2-base amine, effective ingredient B is a Prochloraz, english common name is prochloraz, chemical name is N-propyl group-N-[2-(2,4, the 6-Trichlorophenoxy) ethyl] imidazoles-1-formamide.This kind clothing thinner stable in properties, 54 ± 2 ℃ of sealings are stored after heat in 14 days storage resolution ratio less than 5%, and suspensibility is more than 90%, reach country to kind of the requirement of clothing agent,, be used for coating paddy seeds by adding special film forming agent, do not fade after the immersion, reach the purpose of seed pelleting pesticide-germicide.
The present invention carries out composite with Imidacloprid and Prochloraz, the two is had complementary advantages, the purpose that a dispenser can reach desinsection, cure the disease, not only save time but also laborsaving, rice seedling insect and bakanae disease are had good preventive effect, and it is long to have a lasting period, safety, low toxicity, the significant advantage of synergy.
Mixture by this proportioning is formed carries out toxicity test by horn method with healthy white rat, rabbit, and result of the test is as follows:
(1) the present invention to rat acute per os LD50 greater than 4240mg/kg;
(2) the present invention to rat acute through skin LD50 greater than 2150mg/kg;
(3) the present invention all is nonirritant to tame lagophthalmos, skin.According to the toxicity grading standard is low toxicity.
(4) anti-bakanae disease of rice and seedling stage insect effect:
The present invention has very good sustained diseases prevention, insecticidal action on plant, test method is: under indoor conditions, adopt the dull and stereotyped spore germination method of PDA, measure spore germination number, germination rate, inhibiting rate, obtain EC50 value and co-toxicity coefficient, be co-toxicity coefficient greater than 100 the synergistic effect that is, less than 100 be antagonism, result of the test is as follows:
| The medicament title | Concentration (mg/L) | The spore germination number | Germination rate (%) | Inhibiting rate (%) | EC 50 (mg/L) | Insect preventive effect in seedling stage (%) | Co-toxicity coefficient |
| Pesticidal composition | 1.55 | 128.3 | 42.8 | 53.5 | 0.8647 | 95 | 234.2 |
