Abstract
A synergistic composite insecticide for preventing and treating rice hopper and wheat aphid contains iurfenuron, imidacloprid, assistant and excipient.
Description
Technical field
The present invention relates to a kind of Pesticidal combination and uses thereof, especially a kind of is the Pesticidal combination and the application thereof of main active with Acarus tritici urea and Imidacloprid.
Background technology
Acarus tritici urea (Lufenuron), chemical name: N-[[[2,5-two chloro-4-(1,1,2,3,3,3-hexafluoro third oxygen) phenyl] amino] carboxyl]-2, the 6-difluorobenzamide.Be by the exploitation of Switzerland Syngenta Co.,Ltd, CAS:103055-07-8, its 5% missible oil commodity U.S.A by name removes.
The Acarus tritici urea belongs to benzoyl area kind and kills mite, insecticide, and a kind of insect growth regulator, IGR is a chitin synthesis inhibitor.Be mainly used in 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 etc.Tool stomach toxicity and action of contace poison, the unique insecticidal mechanism of tool: suppress insect decortication, desinsection, to kill ovum effective, insect has eaten and has sprayed the crop that U.S.A removes and stopped to get food in 2 hours, enters dead worm peak in 2-3 days.Be characterized in 1. low toxicity, suitable non-polluted farm product production.2. desinsection kills ovum, kills large and small larva, 14 days lasting periods.3. permeability is strong, positive spray medicine, the dead worm in the back side, dead ovum.4. anti-rain washes away, and spraying rains after back 15 minutes does not influence drug effect.
In China, because Acarus tritici urea import price height, usable floor area is confined on the high part fruit and vegetables of economic value added, the application area is less, can not in the crop pests control, use widely, and the Acarus tritici urea is not seen the control of insect that field crops such as being used in paddy rice, wheat is arranged in the document at home and abroad.
Imidacloprid (Imidacloprid) chemical name is: 1-(6-chloropyridine-3-pyridylmethyl)-N-Nitroimidazoline-2-base amine.Imidacloprid is a nicotinoids super-high-efficient insecticide, has wide spectrum, efficient, low toxicity, low-residual, and insect is difficult for producing resistance, to characteristics such as people, animal, plant and natural enemies securities, and have tag, multiple actions such as stomach toxicity and interior suction.Behind the insect contact medicament, the nervous centralis normal conduction is obstructed, and makes its paralysis dead.Product quick-acting is good, higher preventive effect is promptly arranged in 1 day behind the medicine, and residual life reached about 25 days.Be mainly used in the control sucking pest.Be mainly used in the sucking pest on the crops such as control paddy rice, wheat, cotton, as aphid, leafhopper, thrips, trialeurodes vaporariorum and colorado potato beetle and wheat stem maggot etc.
The synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, still finds no the Pesticidal combination that closes Acarus tritici urea and Imidacloprid up to now.
Rice fulgorid and aphid are under the condition of present long-term prescription, and resistance increases gradually, and the agent of agricultural chemicals list descends gradually to the effect of control of insect, and agriculture chemical compounding can obviously improve drug effect, and delays the generation of pest resistance.
Summary of the invention
1, goal of the invention
The purpose of this invention is to provide a kind of multifunctional insecticide composition and application thereof that prevents and treats rice fulgorid and wheat aphid.
2, technical scheme
For achieving the above object, Acarus tritici urea and Imidacloprid that the present invention will grow the lasting period are composite, obtain the new and effective multifunctional insecticide composition of a class.This insecticide has good preventive effect to the various pests that rice fulgorid and wheat aphid are easy to generate resistance; And the inhibition insect is to the pesticide resistance generation of unitary agent (Acarus tritici urea or Imidacloprid).
The present invention adopts following technical scheme:
A kind of Pesticidal combination is characterized in that it contains the Acarus tritici urea and Imidacloprid is an active ingredient, and wherein weight hundred content of Acarus tritici urea are 0.1～30%, and weight hundred content of Imidacloprid are 0.2～30%, and surplus is auxiliary agent and carrier.
The effective ingredient of above-mentioned desinsection combination is present in the composition with the synergy effective dose.
The preferred weight percentage composition of Acarus tritici urea is 0.5～20% in the above-mentioned desinsection combination, and the preferred weight percentage composition of Imidacloprid is 2～20%.
Above-mentioned desinsection combination is that active ingredient and insecticides adjuvant, excipients are mixed with missible oil with Acarus tritici urea and Imidacloprid.
Above-mentioned Pesticidal combination being is especially is being prevented and treated water rice hopper and wheat aphid in the application that prevents and treats on the resistance homoptera pest.
Above-described auxiliary agent is the one or more combinations in calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound, the polyoxyethylene nonylphenol ether, and excipients comprises dimethylbenzene, solvent naphtha.
Measure through indoor synergism test and to show: be respectively 163-268 by Acarus tritici urea and composite dose of co-toxicity coefficient to water rice hopper of Imidacloprid, test determination shows that all composite dose all has significant synergistic insecticidal action to two kinds of insects; Field control effectiveness test equally also shows the composite dose of effect that the insecticidal effect of water rice hopper and wheat aphid all is significantly higher than corresponding single agent agricultural chemicals that the present invention is all.
The present invention especially can be used for preventing and treating water rice hopper and wheat aphid, and its effect is used apparently higher than its single agent.
3, beneficial effect
Acarus tritici urea that provides of the present invention and Imidacloprid Pesticidal combination can produce higher cooperative synergism, and overcome and delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, has reduced drug cost, has alleviated toxicity.
Pesticidal combination of the present invention compared with prior art produces following beneficial effect: (1) is compared with single agent, and said composition has notable synergistic to insect, has obviously improved control efficiency; (2) one medicines are controlled more, and a dispenser can prevent and treat various pests simultaneously, reduce control recruitment cost; (3) alternative high-toxic pesticide, and reduce the field dosage significantly, effectively reduce environmental pollution and residue of pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with the agent of Acarus tritici urea list, produce and the use cost reduction; (6) suppress the resistance enhancing of insect to agricultural chemicals; (7) reduction is to the toxicity of warm blooded animal.
Embodiment
Embodiments of the invention are the methods that adopt indoor bioassay and field trial to combine.Pass through indoor bioassay, the co-toxicity coefficient after clear and definite two kinds of medicaments are composite by a certain percentage earlier; On this basis, carry out field trial again.
Implementation result:
