Embodiment
Below the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
The invention provides a kind of composition pesticide, said composition contains active component, and active component contains Diacloden, carboxin and tmtd, and the weight ratio of Diacloden, carboxin and tmtd is 1:0.01-90:0.01-90.
In the present invention, the chemical name of Diacloden is 3-(the chloro-1,3-thiazoles of 2--5-ylmethyl)-5-methyl isophthalic acid, 3,5-oxadiazines-4-base fork (nitro) amine.
In the present invention, the chemical name of carboxin is 5,6-dihydro-2-Methyl-N-phenyl-Isosorbide-5-Nitrae-oxathiene-3-formamide.
In the present invention, the chemical name of tmtd is two (dimethylthiocarbamoyl) two sulphur thing.
According to the present invention, although the active component of composition pesticide contains Diacloden, carboxin and tmtd, the weight ratio of Diacloden, carboxin and tmtd is 1:0.01-90:0.01-90, can realize object of the present invention, namely composition pesticide has synergistic effect, and control efficiency is good; Multiple different types of plant pest that mixing occurs can be prevented and treated.But under preferable case, the weight ratio of Diacloden, carboxin and tmtd is 1:0.1-10:0.1-10, more preferably 1:0.3-1.5:0.3-1.5, the synergistic effect of composition pesticide is more remarkable, can further improve control efficiency.
In the present invention, for the total content of active component in composition pesticide without particular/special requirement, conventional consumption can be selected according to the different dosage form of composition pesticide preparation, this is conventionally known to one of skill in the art, such as, based on the gross weight of composition pesticide, the content of active component is 1-95 % by weight.
In the present invention, for other composition in addition to the active ingredient (s in composition pesticide without particular/special requirement, the composition that this area is conventional can be matched as required, such as, dispersant, wetting agent, antifreezing agent, stabilizing agent, preservative, thickener, film forming agent, binding agent, colouring agent and solid inert carrier.Therefore, composition pesticide of the present invention is also containing one or more in dispersant, wetting agent, antifreezing agent, stabilizing agent, preservative, thickener, film forming agent, binding agent, colouring agent and solid inert carrier.These compositions can according to the consumption of the dosage form selection routine of composition pesticide preparation, and this is conventionally known to one of skill in the art, does not repeat them here.
In the present invention, for mentioned component all without particular/special requirement, the material that this area is conventional can be adopted, such as:
Dispersant and wetting agent can for polyvinylpyrrolidone, maleic acid-acrylic acid copolymer sodium salt, sodium methylene bis-naphthalene sulfonate, sodium lignin sulfonate, calcium lignosulfonate, calcium dodecyl benzene sulfonate, succinate sodium sulfonate, pull open in powder, sldium lauryl sulfate, sodium alkyl sulfonate, lauryl sodium sulfate, polyoxyethylene nonylphenol ether and fatty alcohol-polyoxyethylene ether one or more.
Antifreezing agent can be one or more in ethylene glycol, 1,2-PD, glycerine and urea.
Film forming agent can be gum Arabic, animal glue, methylcellulose, ethyl cellulose, sodium cellulose glycolate, polyvinyl alcohol, polyethylene glycol, polyacrylamide, Sodium Polyacrylate and one or more all in polyvinyl acetate, is preferably the mixture of polyvinyl alcohol and equal polyvinyl acetate.
Binding agent can be one or more in starch, gypsum, glucose, polyvinyl alcohol, gum Arabic and dextrin.
Thickener can be one or more in Magnesiumaluminumsilicate, xanthans, polyethylene glycol, polyvinyl alcohol, carboxymethyl cellulose and phenolic resins.
Solid inert carrier can be one or more in clay, silica, diatomite, kaolin, attapulgite, imvite, bentonite, talcum powder and precipitated calcium carbonate.
The material that stabilizing agent, preservative and colouring agent also adopt this area conventional, this is conventionally known to one of skill in the art, does not repeat them here.
Composition pesticide of the present invention can provide with final product form, and namely in composition, each composition mixes; Also can provide with the form of independent preparation by often kind of composition, directly carry out bucket during use and mix.
On the other hand, present invention also offers the agricultural chemicals prepared by composition pesticide as above, wherein, the formulation of agricultural chemicals is suspending agent, suspension seed-coating agent, wetting powder or water dispersible granules.
In the present invention, consider from the angle of Pesticide use method, the formulation of agricultural chemicals is preferably suspension seed-coating agent.
In above-mentioned each formulation, the content of other composition in addition to the active ingredient (s and content and active component is without particular/special requirement, can adopt the proportioning of this area routine, such as:
Aqueous suspension agent contains 5-70 % by weight active component, 0.5-12 % by weight dispersant, 0.5-5 % by weight wetting agent, 0.1-10 % by weight antifreezing agent, other additive of 0-10 % by weight usually as stabilizing agent, preservative, thickener, and surplus is water.Suspending agent usually need wet pulverizing with obtain stable, can flow, the suspension liquid of easy measurement volumes.
Suspension seed-coating agent is usually containing 5-70 % by weight active component, 0.5-12 % by weight dispersant, 0.5-5 % by weight wetting agent, 0.1-10 % by weight antifreezing agent, 0.5-10 % by weight film forming agent, 0.5-5% warning colouration, other additive of 0-10 % by weight is as stabilizing agent, preservative, thickener, and surplus is water.
Wetting powder contains 3-95 % by weight active component, 0.5-10 % by weight dispersant, 0.5-5 % by weight wetting agent, other additive of 0-10 % by weight usually as stabilizing agent etc., and surplus is solid inert carrier, as kaolin etc.
Water dispersible granules contains 3-95 % by weight active component, 0.5-10 % by weight dispersant, 0.5-5 % by weight wetting agent, other additive of 0-10 % by weight usually as stabilizing agent, adhesive, and surplus is solid inert carrier, as kaolin etc.Water dispersible granules makes 10-100 order international standard sieve mesh (1676-152 μm) particle usually, by method preparations such as mist projection granulating, extruder grain, High Rotation Speed granulation, fluidized bed prillings.
In the present invention, for the preparation method of various formulation without particular/special requirement, various method well known in the art can be adopted, do not repeat them here.
It will be understood by those skilled in the art that the various formulations in the present invention can dilute use according to actual needs when reality uses.
The third aspect, the invention provides the application in agricultural chemicals as above one or more plant pests in control leafhopper, aphid, plant hopper, wireworm, cutworm, grub, root rot, stem rot, smut, rust, leaf blight, damping off, bakanae disease and rotten kind.
In the present invention, above-mentioned damage by disease and insect all has generation in various crop.Such as, on the crops such as corn, peanut, cotton, wheat and paddy rice.
In the present invention, the method that agricultural chemicals can adopt this area conventional uses, and such as, directly spreads fertilizer over the fields and uses in field, or carry out field spray use after dilution, or carry out seed treatment.The angle high from agricultural chemicals availability is considered, uses the method for agricultural chemicals preferably to carry out seed treatment with agricultural chemicals.Seed treatment comprises dressing or seed dressing.
