The insecticidal composition provided by the invention consists of sulfoxaflor and flubendiamide. The invention also discloses an insecticide, which consists of the insecticidal composition provided by the invention and the pharmaceutically acceptable adjuvants, and the insecticidal composition takes up 1-80% by weight of the insecticide. The insecticidal effects of the insecticidal composition and the preparation provided by the invention are significantly improved, the synergistic effect is significant, and the insecticidal resistance of the pests can be delayed, so that the insecticidal composition and the preparation of the insecticidal composition can be extensively applied to the agricultural field.
Description
Technical field
The present invention relates to the pesticidal preparations field, relate to specifically a kind of Pesticidal combination and preparation thereof and application.
Background technology
Crop pests is one of Main Agricultural disaster of China, and it has, and kind is many, impact is large, also often break out the characteristics of causing disaster, and its occurrence scope and the order of severity often cause heavy losses to Chinese national economy, particularly agricultural production.
Sucking pest, claim again " five is little " insect, be aphid, coccid, tetranychid, aleyrodid, thrips five class pests, they all thrust the tissues such as the leaf of plant, tender stem, leaf sheath, bud, calyx, fruit, piece root, stem tuber by mouthpart, draw cell juice, destroy Stoma of Leaves, spongy tissue and palisade tissue, and secretion poisonous and harmful substances, the obstruction plant normal growth is grown, thereby causes following Major Diseases 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 significantly to descend.In China, therefore the annual therefore class insect pest of the 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.
Fluorine pyridine worm amine nitrile is the sulfimide insecticide, and sulfimide acts on the nervous system of insect, namely acts on binding site unique in the choline receptor and brings into play insecticidal function.Can enter in the plant corpus through leaf, stem, root absorption, insect sucks rear nervous centralis preaches and is obstructed and dead, is mainly used in preventing and treating sucking pest.It is only effective to sucking pests such as aphid, coccid, aleyrodids that but fluorine pyridine worm amine nitrile uses separately, bad to the lepidoptera pest effect that harm on the agricultural is serious, and easily produce resistance.Lepidoptera is the order second largest in the Insecta, comprises butterfly and moth class, and the overwhelming majority belongs to insect.Lepidoptera pest is very big to murrain, and almost each crop all can be subject to the harm of one or both lepidoptera pests.
Therefore; single use fluorine pyridine worm amine nitrile can not comprehensively protect crops to avoid insect pest; and the control efficiency of fluorine pyridine worm amine nitrile can't farthest protect crops not to be subject to the infringement of insect; therefore need to provide a kind of Pesticidal combination novel, that have higher control efficiency, cover crop avoids the infringement of sucking pest and lepidoptera pest better.
Summary of the invention
In view of this, the object of the invention provides a kind of Pesticidal combination and preparation and application, can prevent and treat simultaneously sucking pest and lepidoptera pest, and have synergistic effect.
For realizing purpose of the present invention, the present invention adopts following technical scheme:
A kind of Pesticidal combination is comprised of fluorine pyridine worm amine nitrile and fipronil bisamide, and the weight ratio of described fluorine pyridine worm amine nitrile and fipronil bisamide is 1:20-20:1, is preferably 1:15-15:1, and more preferably 1:10-10:1 most preferably is 1:5.
Fluorine pyridine worm amine nitrile, chemical name is [1-6-(trifluoromethyl) pyridin-3-yl] ethyl]-λ 4-sulfydryl cyanamide, fluorine pyridine worm amine nitrile is the sulfimide insecticide, sulfimide acts on the nervous system of insect, namely acts on binding site unique in the choline receptor and brings into play insecticidal function.Can enter in the plant corpus through leaf, stem, root absorption, insect sucks rear nervous centralis preaches and is obstructed and dead, is mainly used in preventing and treating sucking pest, such as fleahopper, aphid, aleyrodid, plant hopper and coccid etc.Fluorine pyridine worm amine nitrile is efficient, quick and the longevity of residure is long, without the cross tolerance problem, can effectively prevent and treat nicotinoids, chrysanthemum ester class, organophosphate and carbamate pesticide produces the suction juice class pest of resistance, and low to non-target arthropods toxicity, be the integrated pest control preferred agents.
Fipronil bisamide belongs to Novel ortho benzenedicarboxamide insecticides, activates calcium release channel in blue Buddhist nun's alkali recipient cell, and the property out of control release that causes storing calcium ion is the compound that acts on the blue Buddhist nun's alkali of insect cell acceptor at present few in number.Lepidoptera pest there is the wide spectrum preventive effect, produces without cross resistance with existing insecticide, be suitable for very much the control that existing insecticide produces the insect of resistance.Fipronil bisamide has very outstanding preventive effect to larva, and is limited to the adult preventive effect, do not have ovicidal action, nearly all Lepidoptera class pest is all had good activity, and speed of action is fast, and the lasting period is long.
The present invention also provides a kind of insecticide, is comprised of acceptable auxiliary material on Pesticidal combination of the present invention and the pesticidal preparations.
Wherein, to account for the percentage by weight of described insecticide be 1-80% to described Pesticidal combination.
