Description
Technical field
The present invention relates to a kind of insecticides, being specifically related to a kind of is the composite Pesticidal combination that forms of active ingredient with Acarus tritici urea and ryania acceptor inhibitor insecticides bromine cyanogen insect amide.
Background technology
The Acarus tritici urea, chemical name: RS)-and 1-[2,5-two chloro-4-(1,1,2,3,3,3-hexafluoro propoxyl group) phenyl]-3-(2, the 6-difluoro benzoyl) urea, molecular formula: C

3, structural formula:
The Acarus tritici urea is latest generation substituted urea class insecticide, medicament is by acting on insect larvae, stoping the decortication process to kill off the insect pests, have stomach toxicity and tag, multiple effect of killing ovum, efficient insecticide, especially food leaf caterpillars such as fruit tree there is outstanding preventive effect, tomato noctuid, beet armyworm, flower thrips, cotton bollworm, potato stem borer, tomato rust mite, eggplant moth fruitworm, diamond-back moth etc. are all had good control efficiency.Thrips, rust mite, trialeurodes vaporariorum there is unique mechanism of killing.After the medication, effect first slowly has ovum function extremely, can kill new product worm's ovum, 2-3 days fruits that take effect after the dispenser.The lasting period of medicament is long, is conducive to reduce the laxative number of times; To crop safety, lasting medicine, resistance of rainwater washing against has selectivity to useful arthropods adult.Can be used as good mixed agent and use, lepidoptera pest is had good preventive effect.
The bromine cyanogen insect amide, also be cyanogen insect amide, it is second generation ryania acceptor inhibitor insecticides, this kind is by activating the ryania acceptor of target pest, discharge the calcium in striated muscle and the smooth muscle cell, cause the dead insecticide of insect paralysis, lepidoptera pest and sucking pest are all had the better prevention effect.
Summary of the invention
The present invention is based on the characteristic of Acarus tritici urea and bromine cyanogen insect amide is further studied, utilize the complementarity of the two, finding and proving with Acarus tritici urea and bromine cyanogen insect amide is that active ingredient is carried out composite, can produce tangible synergistic effect, and enlarged prevention and treatment range, reduced use cost on the basis that guarantees control efficiency.
The object of the present invention is to provide a kind of Pesticidal combination of high-efficiency broad spectrum, a kind of Pesticidal combination that contains Acarus tritici urea and bromine cyanogen insect amide, be active ingredient with Acarus tritici urea and bromine cyanogen insect amide, the weight percent content of active ingredient is 20%-70%, and the weight ratio of Acarus tritici urea and bromine cyanogen insect amide is 1:0.1-10.
Acarus tritici urea of the present invention and bromine cyanogen insect amide are commercially available former medicine.
The Acarus tritici urea that the present invention relates to is latest generation substituted urea class insecticide, and this medical instrument has stomach toxicity and tags, multiple effect of killing ovum, efficient insecticide; Be a kind of inhibitor of casting off a skin by working after taking in, this medicine acts on ovum, low instar larvae and the high instar larvae of giving birth in the 24h of back.Suppress insect decortication, desinsection, to kill ovum effective, insect has eaten the crop that has sprayed the Acarus tritici urea and had stopped getting food in 2 hours, enters dead worm peak in 2-3 days.To corn, vegetables, oranges and tangerines, cotton, potato, grape, Soybean and Other Crops control beet armyworm, prodenia litura, tomato moth, diamond-back moth, cotton bollworm, lima bean pod borer, melon thin,tough silk snout moth's larva, oriental tobacco budworm, thrips, rust mite, citrus leaf-miner, plant hopper, potato tuberworm etc., the medicament that can be used as resistance management uses, and is suitable for comprehensive insect pest and administers.
The bromine cyanogen insect amide that the present invention relates to, also be cyanogen insect amide, it is second generation ryania acceptor inhibitor insecticides, this kind is by activating the ryania acceptor of target pest, discharge the calcium in striated muscle and the smooth muscle cell, show as after causing insect to poison and stop to get food, very excited always, excited can not stopping paralysed, paralysis, death at last.Replace Rynaxypyr to contain also forming through modifying of cl radical by cyano group, comparing with Rynaxypyr has higher insecticidal activity and wider insecticidal spectrum.The inventor is through a large amount of discoveries that experimental results show that, the Acarus tritici urea based on stomach toxicity and the action of contace poison to larva, further by the interior absorption of bromine cyanogen insect amide, causes insect to stop to get food mainly by to the biosynthetic inhibition of chitin, and motion is violent, and is dead fast; It is composite to be with Acarus tritici urea and bromine cyanogen insect amide that active ingredient is carried out like this, has higher insecticidal activity, plays the effect of Synergistic, and has enlarged prevention and treatment range, has reduced use cost on the basis that guarantees control efficiency.
In order to reach better control efficiency, the inventor has carried out preferably, and when the weight ratio of described active ingredient Acarus tritici urea and bromine cyanogen insect amide is 1:0.125-5, synergistic function is outstanding; Further, when the weight ratio of described Acarus tritici urea and bromine cyanogen insect amide is 1:0.5-2, control efficiency the best.
