The invention has the following advantages that: after the acetaniprid is compounded with the flubendiamide, the composition has notable synergistic and persistent control effects, the pesticidal spectrum is broadened, and the pesticidal composition has high activity on pests such as rice stem borers, yellow rice borers, cnaphalocrocis medinalises, rice planthoppers, cabbage caterpillars and aphids.
Description
Technical field
The invention belongs to agricultural technology field, relate to a kind of application of Pesticidal combination in paddy rice, vegetables insect pest that contains Acetamiprid and fipronil bisamide.
Background technology
Acetamiprid, English common name acetamiprid, chemical name are E-N '-[(6-chloro-3-pyridine radicals) methyl]-N^ (2)-cyano group-N '-methylacetamide.Acetamiprid belongs to the Nitromethylene heterocycle compound, it is a kind of novel pesticide, act on the nAChR at insect nervous system cynapse position, the neural stimulation conduction of interference insect, cause the nervous system path blockade, cause the accumulation of neurotransmitter acetylcholine, thereby cause the insect paralysis at the cynapse position, final dead.Be widely used in paddy rice, especially the control of insects such as the aphid of vegetables, fruit tree, tealeaves, plant hopper, thrips, Lepidoptera.
Fipronil bisamide, English common name flubendiamide, chemical name be 3-iodo-N '-(2-mesyl-1,1-dimethyl ethyl group N-{4-[1,2,2,2-tetrafluoro-1-(trifluoromethyl) ethyl]-the 0-tolyl phthalamide, molecular formula is C

4S.Belong to novel phthalic amide insecticides, activate calcium release channel in blue Buddhist nun's alkali recipient cell, the property out of control release that causes storing calcium ion.It is the compound that acts on blue Buddhist nun's alkali (Ryanodine) acceptor of insect cell at present few in number.Lepidoptera pest there is the wide spectrum preventive effect, does not have cross resistance with existing insecticide and produce, be suitable for very much the control that existing insecticide produces the insect of resistance.Larva there is very outstanding preventive effect, limited to the adult preventive effect, there is not ovicidal action.Resistance of rainwater washing against is slightly conducted in the back in the infiltration plant body by xylem.
Often there is defective in various degree in the insecticide variety that contains the single-activity component on agricultural insect pests control: use the back insect to be easy to generate pesticide resistance continuously, access times are many will the weighting ring environment pollution.And that different component carries out is composite, can effectively overcome above shortcoming.Simultaneously, utilizing two kinds of synergistic effects that active component is mixed and is produced, can improve preventive effect, reduce the consumption of active ingredient, save drug cost, delay the generation of pest resistance to insecticide, reduce environmental pollution, is the important means of integrated control insect.At present, still nobody reported in the composite and application of Acetamiprid and fipronil bisamide.
Summary of the invention
In order to satisfy the needs of pesticide producing, make full use of two kinds of active components be mixed the synergistic effect that produced, improve preventive effect, reduce agricultural cost and delay the generation of pest resistance to insecticide, the present invention proposes the composite Pesticidal combination that contains Acetamiprid and fipronil bisamide.
The object of the present invention is achieved like this: a kind of Acetamiprid and fipronil bisamide Pesticidal combination of containing comprises effective active component, auxiliary agent and fills out agent that the percentage by weight of effective active composition Acetamiprid and fipronil bisamide is 1～40: 50～1.
The Pesticidal combination of described Acetamiprid and fipronil bisamide, the percentage by weight of Acetamiprid and fipronil bisamide are 5～30: 40～5.
The Pesticidal combination of described Acetamiprid and fipronil bisamide, the percentage by weight of Acetamiprid and fipronil bisamide are 10～20: 30～10.
Described Acetamiprid and fipronil bisamide complex insecticidal composition can be made into wetting powder, water dispersible granules, suspending agent.
When making wetting powder, composition comprises following constituent content: Acetamiprid 1～40%, fipronil bisamide 1～50%, dispersant 5～10%, wetting agent 2～10%, filler 8～92%.
Acetamiprid, fipronil bisamide, dispersant, wetting agent, filler are mixed, in mixed cylinder, mix, after airslide disintegrating mill is pulverized, mix again, promptly can be made into Acetamiprid fipronil bisamide wetting powder.
When making water dispersible granules, composition comprises following constituent content: Acetamiprid 1～40%, fipronil bisamide 1～50%, dispersant 3～12%, wetting agent 1～8%, disintegrant 1～10%, binding agent 1～8%, filler 8～93%.
Acetamiprid, fipronil bisamide, dispersant, wetting agent, disintegrant, filler etc. are obtained the particle diameter that needs through comminution by gas stream together, add other auxiliary agents such as adhesive again, obtain the materials of granulating.It is interior through after granulation and the drying to expect that product are quantitatively sent the fluidized bed granulation dryer to, makes Acetamiprid fipronil bisamide water dispersible granules.
Comprise following constituent content when composition is made suspending agent: Acetamiprid 1～30%, fipronil bisamide 1～30%, dispersant 2～10%, wetting agent 2～10%, defoamer 0.1～1%, thickener 0.1～2%, antifreeze 0.1～8%, stabilizing agent 0.05%～3%, deionized water add to 100%.
Dispersant, wetting agent, defoamer, thickener, antifreeze in the above-mentioned formulation material are mixed through high speed shear, add Acetamiprid, fipronil bisamide, ball milling is 2～3 hours in ball mill, makes diameter of particle all below 5 μ m, makes the Acetamiprid fipronil bisamide suspension agent.
The described Pesticidal combination that contains Acetamiprid and fipronil bisamide is mainly used in control rice-stem borer, paddy stem borer, rice leaf roller, rice fulgorid, vegetables cabbage caterpillar, aphid.
The invention has the advantages that: different fully to the mechanism of action of target pest after (1) Acetamiprid and fipronil bisamide are composite, both are composite to have notable synergistic and lasting effect; (2) enlarged insecticidal spectrum, rice-stem borer, paddy stem borer, rice leaf roller, rice fulgorid, vegetables cabbage caterpillar, aphid have all been had greater activity; (3) reduce the dosage of agricultural chemicals, reduced the residual quantity of agricultural chemicals on crop, alleviated environmental pollution; (4), insect good to person poultry safety, Environmental compatibility is difficult for developing immunity to drugs.
Embodiment
The present invention is described further below in conjunction with embodiment, and the percentage among the embodiment all is weight percentage, but the present invention is not limited thereto.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field trial again.
