Abstract
The invention discloses a nuisance free seed additive for preventing vegetable sprout term disease and its preparation method, wherein the seed additive is prepared from two of metalaxyl, Tolclofos-methyl or hymexaxzol by a predetermined proportion through specific process technology, the seed addictive also comprises surface active agent, dispersing agent, solvent, film-forming agent, and aposematic coloration.
Description
Technical field
The present invention relates to a kind of agricultural chemicals seed treatment, relate in particular to a kind ofly, more relate to a kind of seed treatment that is used to prevent and treat vegetable sprout term disease by metalaxyl, two kinds of composite pesticide seed treatments of tolelofos-methyl.
Background technology
Metalaxyl is a kind of systemic fungicide, can be by the root of plant, and stem, leaf absorbs, and is transmitted to the various piece of plant, the effect of play diseases prevention, curing the disease.Be mainly used in control greengrocery crop frost enzymophathy disease; its chemical name is: N-(2-methoxyl group acetyl group)-N-(2; the 6-3,5-dimethylphenyl)-racemic-α-An Jibingsuan methyl esters; the preparation method of metalaxyl and relevant performance data are in U.S. Pat 3882162; US4267365; existing report on the disclosed data of document such as Us4317916 and Chinese patent 1051916 and Chen Wanyi chief editor " pesticide producing are with synthetic "; existing many enterprises produce the former medicine of this product both at home and abroad at present; being the main agricultural chemicals of preventing and treating vegetable disease at present, is raw material as the former medicine of 95% metalaxyl that can adopt Zhejiang this insecticide factory of standing grain to produce.
Tolelofos-methyl, adopted name: tolclofos-methyl (BSI, E-ISO, (m) F-ISO); Chemical name: O-2,6-two chloro-are right-tolyl O, O-dimethyl disulfide substituted phosphate.Pure product are colourless crystallization, and former medicine is colourless to the light brown solid, 78～80 ℃ of fusing points.This product is phosphorous series bactericidal agent, various germs such as Fungi Imperfecti, Basidiomycetes and Ascomycetes all there is very strong bactericidal activity, seedling blight, stalk break, snow mold etc. there are good control efficiency, have special effect as damping off to plants such as cotton, potato, beets.Because suction-operated is strong, be difficult for running off, in soil, have certain lasting period, gram spills by seed dressing, dipping and soil and uses.
Tolelofos-methyl can be used for foliage spray and seed treatment effectively.Because the awkward water-soluble organic compound of tolelofos-methyl, therefore, the product of traditional tolelofos-methyl is wetting powder or missible oil, and the granularity of pulvis is big, and the absorption ratio of plant is low, be sprayed on the plant after, be detained and manifest serious, cause environmental pollution; And missible oil is owing to contain a large amount of poisonous, hazardous solvent toluene or dimethylbenzene etc., can produce greatly human body and environment during use and pollute.Therefore research and development will be that institute of agricultural sector ten minutes expected with water by the tolelofos-methyl micro emulsion formulation of dispersion medium, also be the directions that develops the green ecotypical agricultural.
The kind clothing agent that circulation is used on market at present mostly is the seed treatment that carbendazim, tmtd etc. are formed.Because such pesticide dosage is big, protection effect is poor, the particle of product is bigger, and in use the availability of active ingredient is lower, can produce bigger pollution to people and environment, does not meet the requirement of green ecological agricultural development to agricultural chemicals.So it is less that research is polluted environment and people, the seed treatment formulation that grain fineness reaches below 1 micron is very necessary.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of nuisance free seed additive of preventing and treating vegetable sprout term disease and preparation method thereof that is used to, to overcome the defective that pulvis and wetting powder exist.
Technical conceive of the present invention is such:
Seed treatment of the present invention is to be dispersion medium with water, by different chemical assistants, water-fast agricultural chemicals is scattered in the water with the smaller particles form.Mainly be to have utilized the pesticidal emulsifiable technology that it is prepared into the seed treatment that has less than 1 micron particles.This seed treatment is compared with the prior seed inorganic agent has bigger advantage on grain fineness and action effect, this product is once seed treatment, promptly have faster to seed conducted inside performance, can be more effectively at the disease situations of crops, accelerate the infiltration of agricultural chemicals to crops tissue, make it can fast Absorption and be transmitted in the plant corpus, the while can be decomposed in plant corpus again very soon, metabolism can not make that persticide residue exceeds standard in the agricultural product.
Seed treatment of the present invention is a kind of composition, and its component and weight percent content comprise:
Metalaxyl 1～15%
Tolelofos-methyl 1～10%
Surfactant 3～30%
Solvent 10～30%
Film forming agent 1～5%
Defoamer 1～3%
Water surplus;
Preferably:
Metalaxyl 1～15% 5%
Tolelofos-methyl 1～10% 8%
Surfactant 3～30% 18%
Solvent 10～30% 22%
Film forming agent 1～5% 3%
Defoamer 1～3% 1.5%
Water surplus;
Wherein:
Said surfactant is selected from the mixture of non-ionic surface active agent and anion surfactant;
In No. 400, non-ionic surface active agent preferred alkyl phenol polyethenoxy ether, fatty alcohol-polyoxyethylene ether, castor oil polyoxyethylene ether, phenol derivatives polyoxyethylene/polyoxypropylene base ether, polyoxyethylene carboxylate, ethyoxyl propoxylated derivative, farming breast or No. 1601 etc. one or more;
The preferred calcium dodecyl benzene sulfonate of anion surfactant (No. 500, farming breast);
The surfactant product of being addressed is the commercially available prod, as the product that can adopt companies such as chemical plant, Lvshun, Nanjing, Nanjing petrochemical industry Co., Ltd, Liaoyang gram difficult to understand chemicals Co., Ltd to produce;
Said solvent is selected from a kind of or its mixture in methyl alcohol, ethanol, isopropyl alcohol, n-butanol, benzene, cyclohexane, hexane, the chloromethanes etc.;
Said film forming agent is selected from one or more in polyvinyl alcohol, polyvinylpyrrolidone, the hydroxypropyl cellulose, especially the mixture of preferably polyethylene alcohol and polyvinylpyrrolidone;
Said defoamer is selected from tributyl phosphate.
According to optimized technical scheme of the present invention, 0.5～2% the warning colouration that also comprises, warning colouration are selected from water capacity dyestuffs such as acid scarlet, rose-red, rose violet, and it mainly acts on is to using the seed of handling from sub-inorganic agent to have indicative function;
Seed treatment preparation method of the present invention comprises the steps:
Under 10～80 ℃ temperature, metalaxyl, tolelofos-methyl, surfactant, solvent are mixed stirring, emulsification thing to be mixed according to a certain percentage and become add film forming agent, defoamer and warning colouration behind the liquid of homogeneous transparent and promptly obtain said seed treatment.
Seed treatment outward appearance of the present invention is transparent or opaque one-tenth emulsion form, and the product particle fineness is less than 1 micron, and the seed consumption is 1～5% of a seed weight, and is stable, not stratified in 0 ℃～55 ℃ scopes.
Because the present invention is a kind of novel no high sea seed treatments, the product particle fineness is all in 1 micron, this seed treatment is compared with the prior seed inorganic agent has bigger advantage on grain fineness and action effect, this product is once seed treatment, promptly have faster to seed conducted inside performance, can be more effectively at the disease situations of crops, accelerate the infiltration of agricultural chemicals to the crops tissue, make it can fast Absorption and be transmitted in the plant corpus, can in plant corpus, can be decomposed very soon again simultaneously, metabolism can not make that persticide residue exceeds standard in the agricultural product.
