Abstract
The invention discloses a compound insecticidal composition containing dinotefuran and fenobucarb and application thereof, and the insecticidal composition takes the dinotefuran and the fenobucarb as main active ingredients, wherein the weight ratio of the dinotefuran to the fenobucarb is (0.1-80):(0.5-80). The insecticidal composition can generate the higher synergy, overcome and stay the drug resistance of pests, realize long desinsection speed and long lasting period and reduce the medicament cost; and the control effect of the insecticidal composition is obviously higher than a single agent. The compound insecticidal composition can be used for controlling homoptera pests, in particular to rice plant hoppers and aphids on crops, and the effects of the compound insecticidal composition are obviously higher than the single agent.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of compound pesticide compositions containing MTI-446 and Bassa and uses thereof.
Background technology
MTI-446 (dinotefuran), chemical name: 1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine, white crystal, 107.5 ℃ of fusing points, 94.5～101.5 ℃ of industrial goods, vapour pressure<1.7 * 10-6pa(30 ℃), density 1.33(25 ℃).Solvability is water 40g/L, is insoluble in cyclohexane, solvent wet goods organic solvent.Structural formula is:
MTI-446 is fool proof to mammal, and its acute oral LD50 is male rat 2450mg/kg, female rats 2275mg/kg; Male mice 2840mg/kg, female mice 2000mg/kg.To rat acute through skin LD50 2000mg/kg (female, hero).Without teratogenesis, carcinogenic and mutagenicity.MTI-446 is also fool proof to aquatile.Ichthyotoxin is tested and is shown, MTI-446 is to carp nm (48h) > 1000mg/L, to water flea > 1000mg/L; Equally, MTI-446 is also very low to birds toxicity, to quail acute oral LD50 > 1000mg/kg. is through honeybee test is learnt, and MTI-446 is to honeybee safety, and do not affect honeybee producting honey.This medicament insecticidal spectrum is wide, has remarkable interior sorptivety and thoroughly acts on, and shown very high insecticidal activity at very low dosage.This medicament is fool proof to mammal, birds and aquatile, and crop, without poisoning, be can be used for to numerous crops such as paddy rice, fruit tree, vegetables.
Bassa (Fenobucarb) chemical name is: 2-secondary butyl phenenyl-N-methyl carbamate.Structural formula is as follows:
Bassa belongs to carbamate insecticide, mainly by acetylcholine esterase inhibition, insect is poisoned to death.Plant hopper, spider mite kind are had to special efficacy, and desinsection is rapid, but residual effect is short, can only maintain 4-5 days.
But rice fulgorid and aphid are under the condition of current long-term prescription, and resistance increases gradually, and the agricultural chemicals single dose descends gradually to the effect of control of insect.The inventor finds after deliberation, and the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, not yet finds up to now the Pesticidal combination of relevant MTI-446 and Bassa.
Summary of the invention
The purpose of this invention is to provide a kind of compound pesticide compositions containing MTI-446 and Bassa, this Pesticidal combination is the multifunctional insecticide composition of control homoptera pest.
Another object of the present invention is to provide this Pesticidal combination and prevents and treats the application on the insecticidal materials of resistance homoptera pest in preparation, particularly in preparation, anti-eliminates aphis, the application on the insecticidal materials of aleyrodid and plant hopper.
The objective of the invention is to be achieved through the following technical solutions:
A kind of compound pesticide compositions containing MTI-446 and Bassa, it is main active ingredient that this Pesticidal combination be take MTI-446 and Bassa, wherein, the weight ratio of MTI-446 and Bassa is 0.1～80:0.5～80.Be preferably 0.5～50:2～50, more preferably 0.5～10:4～30.In this Pesticidal combination, effective ingredient is present in composition with the synergy effective dose.
In compound pesticide compositions of the present invention, the two weight percentage that accounts for composition of MTI-446 and Bassa is 3～80%.Be preferably 5～55%, most preferably 10～40%.
Compound pesticide compositions of the present invention be take MTI-446 and Bassa and is mixed with any one formulation allowed on agricultural chemicals, the preferred emulsion of described formulation, suspending agent, wetting powder, aqueous emulsion, microemulsion and water dispersion granule as main active ingredient and insecticides adjuvant and excipient.
Auxiliary agent can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, the rare block compound of polyoxyethylene polyoxy third (as agriculture breast 33
#), polyoxyethylene nonylphenol ether etc., excipient comprises isopropyl alcohol, vegetable oil, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can alone or and use.
The multiple homoptera pest that Pesticidal combination of the present invention easily produces resistance to rice fulgorid and aphid etc. has good preventive effect; And the inhibition insect is to the pesticide resistance generation of unitary agent (MTI-446 or Bassa are arbitrary).
Above-mentioned compound pesticide compositions is prevented and treated the application on this medicine of resistance homoptera pest desinsection in preparation, and especially the effect on the Pesticidal combination of control aleyrodid, plant hopper or aphid is remarkable.
Beneficial effect of the present invention compared with prior art: (1) is compared with single dose, said composition antagonism homoptera pest has obvious synergistic function as rice fulgorid, aphid etc., overcomes and has delayed pest resistance to insecticide, and expanding prevention is composed, desinsection speed is fast, has obviously improved control efficiency; (2) reduce control recruitment, drug cost; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with the Bassa single dose with MTI-446, produce and the use cost reduction; (6) suppress the resistance enhancing of homoptera pest to agricultural chemicals, its successful is used higher than its single dose.
