Abstract
The invention discloses a corn seed coating agent, which relates to the seed coating agent, and is characterized in that the raw materials comprise 3.5-7.5% of film forming agent, 0.2-0.5% of plant-growth regulator, 1-2% of dispersant, 2-4% of wetting agent, 0.1-0.3% of thickening agent, 5-20% of antifreezing agent, 0.2-5% of warning color, 2.5-5% of pesticide and 13-23% of bactericide. Water is added in the film forming agent according to weight proportion of 1:29-13, and then raw materials are added and uniformly mixed and grinded. The bactericide thiram/tebuconazole are added with weight proportion of 10-20/3, and the pesticide is cypermethrin.
Description
Technical field
The present invention relates to formulation, be applied to chemical protection of plant field, a kind ofly specifically take the corn seed that cypermethrin, Tebuconazole, tmtd be Main Ingredients and Appearance.
Background technology
Cypermethrin
,molecular formula is C22H19CL2NO3, and molecular weight is 416.32, and former medicine is faint yellow to brown thick liquid or semisolid.Refractive index n
25 d1.5650, vapour pressure 5.066 * 10
-6pa (70 ℃), 190 * 10
-9pa (being extrapolated to 20 ℃), relatively close virtue approximately 1.2350 (25 ℃).In the time of 20 ℃, solvability is: acetone >450g/L, ethanol 337g/L, dimethylbenzene >450g/L, chloroform >450g/L, hexane 103g/L; Former medicine is solvability 0.01～0.2mg/L (21 ℃) in water.To thermally-stabilised, 220 ℃ are not decomposed below, more stable in acid medium, and field trial is stable to light, and alkali condition is unstable.Pyrethroid insecticides, is broad spectrum pesticide safely and effectively, has that strong solution is killed, an effect such as stomach toxicity and prevention are ingested.
Tebuconazole, chemical name: (RS)-1-(4-chlorphenyl)-4,4-dimethyl-3-(1H-1,2,4 triazol-1-yl methyl) penta-3-alcohol, molecular formula: C16H22ClN3O, molecular weight: 307.8, former medicine is clear crystal, fusing point is 102.4 ℃, vapour pressure 0.0133mPa(20 ℃): solvability (20 ℃): water 32mg/L, toluene 50-100g/L.Tebuconazole is a kind of efficient, wide spectrum, interior absorption triazole bactericidal agent, has protection, treats, roots out three large functions, and fungicidal spectrum is wide, the lasting period is long.These product are used for preventing and treating sclerotinia rot of colza, and not only preventive effect is good, and have resistant to lodging, the feature such as production-increasing function is obvious.
Tmtd, molecular formula: C6H12N2S4, molecular weight: 240.44, density: 1.29; 1.39～1.40(20/4 ℃), fusing point: 146～148 ℃, flash-point: higher than 300 ℃.Good fortune U.S.A of broad spectrum protection is a bactericide, to various crop downy mildew, epidemic disease, anthracnose, Cereal smut, seedling stage yellow blight have good control.Single dose is used, and the property of medicine is single, and can not play can desinsection, effect that again can sterilization.
Summary of the invention
Object of the present invention be take exactly cypermethrin, Tebuconazole, tmtd and is carried out compositely as effective ingredient, can give full play to advantage separately and have the effect that strengthens drug effect.The object that a dispenser can reach desinsection, cure the disease, plays mutual supplement with each other's advantages, not only saves trouble but also laborsaving.
The present invention is compound insecticidal sterilization pesticide mixture, and component A, component B, component C are effective ingredient.Effective ingredient A is cypermethrin, and effective ingredient B is Tebuconazole, and effective ingredient C is tmtd.Effective ingredient cypermethrin accounts for 2.5 ~ 5% of mixture gross weight, Tebuconazole accounts for 3% of mixture gross weight, tmtd accounts for 10 ~ 20% of mixture gross weight, dispersant 1 ~ 2%, wetting agent 2 ~ 4%, thickener 0.1 ~ 0.3%, antifreezing agent 5 ~ 20%, warning colouration 0.2 ~ 5%, film forming agent 3.5 ~ 7.5%, water 35.7 ~ 83.2%.After component is determined by best proportioning, respectively the cypermethrin measuring, Tebuconazole, tmtd, dispersant, wetting agent, thickener, antifreezing agent, warning colouration, film forming agent, water are dropped into mixing kettle and stirs, enter sand mill and be ground to the little space 5um of particle diameter, discharging, analyzes qualified packing.
The present invention's combination measures by best proportioning, fully mixes, and after the sand mill sand milling of footpath, remembers processed finished products.Said preparation stable chemical nature, 54 ± 2 ℃ of sealed type storages after heat in 14 days storage resolution ratio is less than 5%, and suspensibility is more than or equal to 90%, reaches the requirement of country to seed coat agent, the present invention passes through composite, the efficient insecticide of combined chloride Cyano chrysanthemate, Tebuconazole, tmtd, the advantage of sterilization.From the mechanism of action, have that insecticidal activity is high, the potential of sterilization wide spectrum may.
embodiment:
Below in conjunction with example, further narrate the present invention
