Abstract
The invention discloses an insecticidal composition and preparation and application thereof. The insecticidal composition is made of cyantraniliprole and nitenpyram in a weight ratio of 1:0.1-10. The insecticidal composition is made of pesticide preparation acceptable auxiliaries. The insecticidal composition accounts for 1%-80% of insecticide. The insecticidal effect of the insecticide is evidently improved, the insecticide can be used for controlling lepidopteran pests, hemiptera pests, colopteran pests, homopterous pests and part of thysanoptera pests, generation of drug resistance of the pests is retarded, cost in drug use is lowered greatly, the insecticide is highly safe for human, livestock and environment and is widely applicable to wheat, rice, cotton, vegetables, fruit trees and the like.
Description
Technical field
The present invention relates to the pesticidal preparations field, relate to a kind of Pesticidal combination and preparation thereof and application specifically.
Background technology
Sucking pest; Claim " five is little " insect again; Be aphid, coccid, tetranychid, aleyrodid, thrips five class pests, they all thrust the tissue of the leaf of plant, tender stem, leaf sheath, bud, calyx, fruit, piece root, stem tuber etc. through mouthpart, draw cell juice; Destroy blade pore, spongy tissue and palisade tissue; Poisonous, the harmful substance of justacrine hinders plant normal growth and grows, thereby causes following main disease symptom: make blade chlorisis, jaundice, rubescent, shrivelled or formation insect gall; Disease bud deformity; Make blade, pericarp be rust; Make blade become the felt shape; Cause dehiscent fruit.Can make plant defoliation, fallen flowers, shedding when serious, even the large tracts of land plant is withered, causes yield and quality to descend significantly.In China, therefore the annual therefore type insect pest of crops such as paddy rice, vegetables and the loss that suffers is very serious uses the insecticide of control sucking pest significant to protection crops normal growth.
The insecticide variety that is used to prevent and treat sucking pest at present is more, and like Imidacloprid, Acetamiprid, but the long-term use of these insecticides makes insect resistance occur easily.Nitenpyram has remarkable interior absorption, osmosis, wide, the no poisoning of safety of insecticidal spectrum, is the regeneration product of control sucking pest such as trialeurodes vaporariorum, aphid, pear sucker, leafhopper, thrips.But Nitenpyram is invalid for pests with chewing mouthparts such as Lepidoptera beet armyworm, coleoptera weevil etc.
Crops multiple often insect pest when insect pest takes place takes place simultaneously, therefore, provides a kind of and can prevent and treat various pests and significant to the good insecticide of pests with chewing mouthparts preventive effect simultaneously.
Summary of the invention
In view of this; The object of the invention provides a kind of Pesticidal combination and preparation and application; Make its sucking pest and the pests with chewing mouthparts that can prevent and treat Lepidoptera, Semiptera, coleoptera, Homoptera and thrips simultaneously, and the control of the pests with chewing mouthparts of Lepidoptera and coleoptera is had synergistic effect.
For realizing the object of the invention, the present invention adopts following technical scheme:
A kind of Pesticidal combination is made up of cyanogen insect amide and Nitenpyram, and the weight ratio of said cyanogen insect amide and Nitenpyram is 1: 0.1-10.
Cyanogen insect amide (cyantraniliprole) is a kind of novel O-formammidotiazol-benzamide insecticide that du pont company develops.Cyanogen insect amide belongs to insect ryania acceptor inhibitor; Mainly discharge to show and tag and stomach poison function through the intracellular calcium ion of inducing insect ryania receptor modulators; Can be used for the control of insect on the various crop such as paddy rice, vegetables, cotton; Especially the control to various lepidoptera pests has special efficacy, other commercialization insecticide varieties that its control efficiency obviously is superior to using in the current production, and there are not cross resistance in other insecticides.Based on this, cyanogen insect amide is described as efficient pesticides of new generation in the world.
Nitenpyram chemistry (E)-N-(6-chloro-3-picolyl) by name-N-ethyl-N '-methyl-2-; The nitro ethylene diamine belongs to the nicotimine compounds, is another novel product of exploitation after Imidacloprid, Acetamiprid.Have remarkable interior absorption, osmosis, wide, the no poisoning of safety of insecticidal spectrum.It is the regeneration product of control sucking pest such as trialeurodes vaporariorum, aphid, pear sucker, leafhopper, thrips.Mainly act on the insect nerve axle shape cynapse acceptor of insect is had the nerve block effect, similar with other anabasine compound.
Cyanogen insect amide is different with the Nitenpyram structure; The mechanism of action is different; The Pesticidal combination of being made up of cyanogen insect amide and Nitenpyram has enlarged insecticidal spectrum, can prevent and treat the sucking pest and the pests with chewing mouthparts of Lepidoptera, Semiptera, coleoptera, Homoptera and thrips simultaneously, the generation that has slowed down pest resistance to insecticide simultaneously; Reduced drug cost significantly, and people, animal, environment have been had high safety.
The different insecticides active component mixes each active component of back because the difference of composition, structure, physicochemical property makes that the synergy between each active component is typically expressed as synergistic effect, summation action or antagonism.So-called synergistic effect is exactly the mutual synergism between different material, and the effect of its generation is greater than the sum total of each composition effect; And being exactly the effect of its generation, summation action equals the sum total of each composition effect; Antagonism is meant that a kind of material disturbed the effect of another kind of material when two kinds of materials acted on living organism, or the effect of interfering with an opponent each other, the phenomenon that general effect is descended.
The present invention estimates two kinds of mixed interactions of different activities component according to the invention with reference to Sun Yunpei (Sun YP) method; Wherein, Co-toxicity coefficient obviously is synergistic effect greater than 100, and co-toxicity coefficient is significantly less than 100 and is antagonism, and co-toxicity coefficient equals 100 and is summation action.The present invention estimates both and uses the back effect with through calculating the co-toxicity coefficient after cyanogen insect amide and Nitenpyram are used with, and the result shows that the weight ratio of said cyanogen insect amide and Nitenpyram is 1: the co-toxicity coefficient of 0.1-10 is all greater than 100.Find that through outdoor biological activity determination test the weight ratio of said cyanogen insect amide and Nitenpyram is 1: the mixed of 0.1-10 is used has the notable synergistic effect.
Preferably, the weight ratio of said cyanogen insect amide and Nitenpyram is 1: 0.15-1.5, more preferably 1: 0.4-1.
In a specific embodiment, the present invention serves as the test insect with homoptera pest aphid, plant hopper and Lepidoptera pests with chewing mouthparts beet armyworm and coleopteran pest weevil, detects the drug effect of Pesticidal combination according to the invention.The result shows; When each active component consumption in the said Pesticidal combination during less than this absorption of active ingredient of single use; The preventive effect of Pesticidal combination according to the invention is higher than the preventive effect of single use active component; Show that each active component does not have cross tolerance in the Pesticidal combination according to the invention, control efficiency has synergistic effect.Therefore, the present invention also provides said Pesticidal combination in the application in control Homoptera, Lepidoptera, coleopteran pest.
Pesticide original medicine generally can not directly use, and must process and be mixed with pesticidal preparations, could use.Therefore the present invention also provides a kind of formulation of insecticides, is processed by Pesticidal combination according to the invention and conventional auxiliary agent and carrier.
Wherein, the percentage by weight that accounts for said insecticide as preferred said Pesticidal combination is 1%-80%, more preferably 5%-50%.
