Abstract
A synergistic composite insecticide for preventing and treating beet noctuid and rice borer contains flufenoxuron, organophosphorus insecticides, assistant and excipient.
Description
One, technical field
The present invention relates to a kind of Pesticidal combination and uses thereof, especially a class is the Pesticidal combination and the application thereof of main active with flufenoxuron and organophosphorus insecticides.
Two, technical background
Flufenoxuron (flufenoxuron), chemical name: 1-[4-(a-three fluoro-are to toloxyl for 2-chloro-a, a)-2-fluorophenyl]-3-(2,6-two fluorobenzoyl) urea belongs to the benzoyl area kind insect growth regulator, IGR, and it is synthetic to suppress insect chitin, control but the worm mite is double, active high, the lasting period is long.Have and tag and stomach poison function, no systemic action.By suppressing chitinous formation, insect can not normally be casted off a skin and metamorphosis, especially to the control of normally casting off a skin and growing of larva, reach the purpose of desinsection.This medicament also has good blade face anelasticity.Can be used for preventing and treating the mite class and the insect of citrus, cotton, vegetables, soybean, fruit tree, corn, seeding corn and other crops field mezzanine level, to predacious mite and insect safety.But relatively chrysanthemum ester insecticide is slow for the quick-acting of flufenoxuron insecticide, and influence is to the general control of insect, and is especially relatively poor to explosive pest controling effect.
In China, because flufenoxuron 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 flufenoxuron 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.
Chlopyrifos, orthene, phoxim belong to organophosphorus insecticides, belong to neurovirulent fast-acting insecticide, most of lepidoptera pest is had higher preventive effect, and be that toxicity is low, insecticidal spectrum is wide, have tag, stomach toxicity and fumigation action, the agricultural chemicals that has also has acaricidal action.It is the reasonable substitute of high malicious organophosphorous pesticide.But the organic phosphorous insecticide lasting period is short, and on the low side to the lepidopterous larvae insecticidal activity more than 2 ages.Thereby use single agent kind all can not reach best pest controling effect separately.
The synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, still finds no up to now and closes flufenoxuron and organic phosphorous insecticide Pesticidal combination.
Lepidoptera pest as cabbage caterpillar, cotton bollworm, aphid, beet armyworm, the snout moth's larva of rice etc., increases gradually in present resistance, 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.
Three, 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 Lepidoptera, Homoptera and Acarina.
2, technical scheme
For achieving the above object, will the lasting period long flufenoxuron of the present invention respectively with chlopyrifos, orthene, phoxim, wherein a kind of composite, obtain the new and effective multifunctional insecticide composition of a class, wherein the weight ratio of flufenoxuron and chlopyrifos, orthene or phoxim is 0.1～10: 5～60, and the weight ratio of preferred flufenoxuron and chlopyrifos is 0.1～10: 5～40; The weight ratio of flufenoxuron and orthene is 0.1～10: 5～60; The weight ratio of flufenoxuron and phoxim is 0.1～10: 10～40, and most preferably the weight ratio of flufenoxuron and chlopyrifos is 0.5～5: 10～35; The weight ratio of flufenoxuron and orthene is 0.5～5: 10～50; The weight ratio of flufenoxuron and phoxim is 0.5～5: 10～30.
This insecticide has good preventive effect to the various pests that Lepidoptera, Homoptera and Acarina etc. are easy to generate resistance; And the inhibition insect is to the pesticide resistance generation of unitary agent.
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.
3, beneficial effect
Purpose of the present invention just provides the Pesticidal combination of a kind of flufenoxuron and chlopyrifos, orthene, phoxim a kind of composition wherein, it compared with prior art, can produce higher cooperative synergism, overcome and delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, has reduced drug cost, has alleviated toxicity.
The present invention especially can be used for preventing and treating the snout moth's larva of rice and beet armyworm, and its effect is used apparently higher than its single agent.
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 lepidoptera pest, 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 flufenoxuron list, produce and the use cost reduction; (6) suppress the resistance enhancing of lepidoptera pest to agricultural chemicals; (7) reduction is to the toxicity of warm blooded animal.(8) especially can be used for preventing and treating the present serious snout moth's larva of rice of taking place at home: rice leaf roller, striped rice borer, paddy stem borer.
