Abstract
A synergistic composite insecticide for preventing and treating rice borer, beet noctuid and high-resistance plutella xylostella larva contains high-effect cypermethrin, flufenoxuron, assistant and excipient.
Description
One, 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 beta-cypermethrin and flufenoxuron.
Two, background technology
Beta-cypermethrin (efficient alphamethrin) chemical name is: (1R, S)-suitable, trans-2,2-dimethyl-3-(2, the 2-dichloroethylene)-cyclopropane-carboxylic acid-(R, S)-alpha-cyano-3-phenoxy benzyl ester.
Chemical structural formula is:
Beta-cypermethrin has very high stomach toxicity and action of contace poison to insect, knock down rapidly, the tool ovicidal activity, good stability is arranged on plant, the anti-rain drop erosion of energy, effect length is stablized, held to photo-thermal, mammalian toxicity is lower than cypermethrin, drug effect is 2 times of cypermethrins, this product insecticidal spectrum is wide, to Lepidoptera on the crops such as cotton, vegetables, fruit tree, Semiptera, diptera, Homoptera, coleoptera, etc. sanitary insect pest such as agriculture and forestry injurious insect and mosquitos and flies, cockroach, flea, bedbug, louse, ant all have high killing effect.
Flufenoxuron (flufenoxuron) belongs to the benzoyl area kind insect growth regulator, IGR, and it is synthetic to suppress insect chitin, controls but the worm mite is double, and 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, 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.
The synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve desinsection quick-acting and lasting effect, still finds no the Pesticidal combination that closes beta-cypermethrin and flufenoxuron up to now.
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 pest.
2, technical scheme
For achieving the above object, beta-cypermethrin and flufenoxuron assembly that the present invention will grow the lasting period obtain the new and effective multifunctional insecticide composition of a class.This insecticide has good preventive effect to the various pests that Lepidoptera is easy to generate resistance; And suppress insect the pesticide resistance of unitary agent (in beta-cypermethrin or the flufenoxuron arbitrary) is produced.
A kind of Pesticidal combination is characterized in that it contains beta-cypermethrin and flufenoxuron is an active ingredient, and wherein the weight ratio of beta-cypermethrin and flufenoxuron is 0.1～30: 0.5～30.
Above-mentioned effective ingredient is present in the composition with the synergy effective dose.
The preferred weight ratio of beta-cypermethrin and flufenoxuron is 0.5～20: 1～25.
The optimum weight ratio of beta-cypermethrin and flufenoxuron is 1～10: 1～15.
Pesticidal combination of the present invention is that active ingredient and insecticides adjuvant and excipients are formulated with beta-cypermethrin and flufenoxuron.
Pesticidal combination of the present invention is in the application that prevents and treats on the resistance lepidoptera pest, especially in the application that prevents and treats on the snout moth's larva of rice and cabbage caterpillar, the beet armyworm.
Above-described auxiliary agent is that calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxypropylene block compound are (as farming breast 33
#), the one or more combinations in the polyoxyethylene nonylphenol ether, excipient comprises dimethylbenzene, solvent naphtha.Above auxiliary agent, excipient can be singly with or and also can add other auxiliary material with reaching.
Measure through indoor synergism test and to show: is 156-238 by beta-cypermethrin and flufenoxuron to the co-toxicity coefficient of beet exigua larvae, and 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 beet tops moth larvae all is significantly higher than corresponding single agent agricultural chemicals that the present invention is all.
3, beneficial effect
The Pesticidal combination that a kind of beta-cypermethrin and flufenoxuron are provided of the present invention, it compared with prior art, can produce higher cooperative synergism, can both improve the performance of its quick-acting, again can be arranged certain lasting period, 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 resistance cabbage caterpillar, 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 single agent product, 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.
Four, 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:
