Embodiment
Below the specific embodiment of the present invention is elaborated.Should be understood that, embodiment described herein only is used for description and interpretation 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.
Among the present invention, the chemical name of Diacloden is 3-(2-chloro-1,3-thiazoles-5-ylmethyl)-5-methyl isophthalic acid, 3,5-oxadiazines-4-base fork (nitro) amine.
Among the present invention, the chemical name of carboxin is 5,6-dihydro-2-methyl-N-phenyl-Isosorbide-5-Nitrae-oxathiene-3-formamide.
Among the present invention, the chemical name of tmtd is two (dimethyl thiocarbamoyl) two sulphur things.
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 purpose of the present invention, be that composition pesticide has synergistic effect, control efficiency is good; Can prevent and treat multiple different types of plant pest of mixed occurrence.But under the preferable case, the weight ratio of Diacloden, carboxin and tmtd is 1:0.1-10:0.1-10,1:0.3-1.5:0.3-1.5 more preferably, and the synergistic effect of composition pesticide is more remarkable, can further improve control efficiency.
Among the present invention, for the total content of active component in composition pesticide without specific (special) requirements, can select conventional consumption according to the different dosage form of composition pesticide preparation, this is conventionally known to one of skill in the art, for example, based on the gross weight of composition pesticide, the content of active component is the 1-95 % by weight.
Among the present invention, for the composition of other except active component in the composition pesticide without specific (special) requirements, can match as required this area composition commonly used, for example, 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 also contains one or more in dispersant, wetting agent, antifreezing agent, stabilizing agent, preservative, thickener, film forming agent, binding agent, colouring agent and the solid inert carrier.These compositions can be 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.
Among the present invention, all without specific (special) requirements, can adopt this area material commonly used for mentioned component, for example:
Dispersant and wetting agent can be 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 sulfonates, pull open in powder, sldium lauryl sulfate, sodium alkyl sulfonate, lauryl sodium sulfate, polyoxyethylene nonylphenol ether and the fatty alcohol-polyoxyethylene ether one or more.
Antifreezing agent can be in ethylene glycol, 1,2-PD, glycerine and the urea one or more.
Film forming agent can be gum Arabic, animal glue, methylcellulose, ethyl cellulose, sodium cellulose glycolate, polyvinyl alcohol, polyethylene glycol, polyacrylamide, Sodium Polyacrylate and equal one or more in the polyvinyl acetate, is preferably polyvinyl alcohol and equal mixtures of polyvinyl acetate.
Binding agent can be in starch, gypsum, glucose, polyvinyl alcohol, gum Arabic and the dextrin one or more.
Thickener can be in Magnesiumaluminumsilicate, xanthans, polyethylene glycol, polyvinyl alcohol, carboxymethyl cellulose and the phenolic resins one or more.
Solid inert carrier can be in clay, silica, diatomite, kaolin, attapulgite, imvite, bentonite, talcum powder and the precipitated calcium carbonate one or more.
Stabilizing agent, preservative and colouring agent also adopt this area material commonly used, and 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 the finished product form, and namely each composition mixes in the composition; Also can every kind composition provide with the form of independent preparation, directly carry out bucket during use mixed.
On the other hand, the present invention also provides aforesaid composition pesticide prepared agricultural chemicals, and wherein, the formulation of agricultural chemicals is suspending agent, suspension seed-coating agent, wetting powder or water dispersible granules.
Among the present invention, consider from the angle of agricultural chemicals using method, the formulation of agricultural chemicals is preferably suspension seed-coating agent.
Other composition in above-mentioned each formulation except active component and the content of content and active component thereof can adopt the proportioning of this area routine without specific (special) requirements, for example:
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 such as stabilizing agent, preservative, thickener usually, and surplus is water.Suspending agent usually need wet pulverizing stable to obtain, can flow, the easy suspension liquid of measurement volumes.
Suspension seed-coating 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, 0.5-10 % by weight film forming agent usually, the 0.5-5% warning colouration, other additive of 0-10 % by weight such as stabilizing agent, preservative, thickener, surplus are 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 such as stabilizing agent etc. usually, and surplus is solid inert carrier, such 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 such as stabilizing agent, adhesive usually, and surplus is solid inert carrier, such as kaolin etc.Water dispersible granules is made 10-100 order international standard sieve mesh (1676-152 μ m) particle usually, can pass through the method preparations such as mist projection granulating, extruder grain, High Rotation Speed granulation, fluidized bed prilling.
Among the present invention, without specific (special) requirements, can adopt the whole bag of tricks well known in the art for the preparation method of various formulations, not repeat them here.
It will be understood by those skilled in the art that the various formulations among the present invention can dilute use according to actual needs when reality is used.
The third aspect the invention provides the application in aforesaid agricultural chemicals 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 mashed the kind.
Among the present invention, above-mentioned damage by disease and insect all has generation on various crop.For example, on the crops such as corn, peanut, cotton, wheat and paddy rice.
Among the present invention, agricultural chemicals can adopt this area method commonly used to use, and for example, directly spreads fertilizer over the fields in the field and uses, or carry out field spray after the dilution and use, or carry out seed treatment.Consider from the angle that the agricultural chemicals availability is high, the method for use agricultural chemicals is preferably with agricultural chemicals carries out seed treatment.Seed treatment comprises dressing or seed dressing.
