Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of compound pesticide compositions that contains MTI-446 and Profenofos 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).No teratogenesis, carcinogenic and mutagenicity.MTI-446 is also fool proof to aquatile.The ichthyotoxin test shows that MTI-446 is to carp nm (48h)＞1000mg/L, to water flea＞1000mg/L; Equally, MTI-446 is also very low to birds toxicity, and through the honeybee test is learnt, MTI-446 is to honeybee safety to quail acute oral LD50＞1000mg/kg., and do not influence honeybee producting honey.This medicament insecticidal spectrum is wide, has remarkable interior suction osmosis, and has promptly shown very high insecticidal activity at very low dosage.This medicament is fool proof to mammal, birds and aquatile, and crop is not had poisoning, can be used for numerous crops such as paddy rice, fruit tree, vegetables.
Profenofos is the moderate toxicity insecticide.Chemical formula: O-(4-bromo-2-chlorphenyl)-O-ethyl-S-propyl group-thiophosphate, structural formula is:
This insecticide does not have chronic toxicity, and no carcinogenic, teratogenesis, mutagenesis have no stimulation to skin, and is poisonous to fish, bird, honeybee.Profenofos belongs to the asymmetric high osmosis type broad-spectrum organophosphorous pesticide of ternary, has to tag and stomach toxicity, stifling, straight osmosis, can directly permeate in blade and polypide, thoroughly kill hide in blade in (back side), the paddy field, fruit neutralizes and pierces stalk.Profenofos is the thiophosphate insecticides that a kind of molecule contains positive rosickyite base, and its insecticidal spectrum is wide, easily biological-degradable, and the antagonism insect shows high biologically active.Can be used for preventing and treating insects such as cotton bollworm on the crops such as paddy rice, cotton, fruit tree, vegetables, two paddy stem borers (borer) beet webworm, rice water weevil, Liriomyza, small brown rice planthopper, scotellaris, heart-eating worm, aphid.
But homoptera pest, particularly 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 to the effect of control of insect gradually.The inventor finds that after deliberation the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, does not find the Pesticidal combination of relevant MTI-446 and Profenofos up to now as yet.
Summary of the invention
The purpose of this invention is to provide a kind of compound pesticide compositions that contains MTI-446 and Profenofos, this Pesticidal combination is the multifunctional insecticide composition of control homoptera pest.
Another object of the present invention provides this Pesticidal combination and prevents and treats the application on the insecticidal materials of resistance homoptera pest in preparation, particularly the application on the insecticidal materials of preparation control aleyrodid, plant hopper or aphid.
The objective of the invention is to realize through following technical scheme:
A kind of compound pesticide compositions that contains MTI-446 and Profenofos; This Pesticidal combination is main active ingredient with MTI-446 and Profenofos, and wherein, the weight ratio of MTI-446 and Profenofos is 0.1～80: 0.5～80; Be preferably 0.5～50: 2～50, further be preferably 0.5～10: 4～30.Effective ingredient is present in the composition with the synergy effective dose in this Pesticidal combination.
In compound pesticide compositions of the present invention, the two weight percentage in this compound pesticide compositions of MTI-446 and Profenofos is 3%～80%.Be preferably 5%～55%, most preferably 10%～40%.
Compound pesticide compositions of the present invention is that main active ingredient and insecticides adjuvant and excipient are mixed with any one formulation that allows on the agricultural chemicals, the preferred emulsion of described formulation, suspending agent, wetting powder, aqueous emulsion, microemulsion or water dispersion granule with MTI-446 and Profenofos.
Auxiliary agent can adopt calcium dodecyl benzene sulfonate, APES, polyoxyethylene polyoxy third rare block compound (like farming breast 33
#), NPE etc., excipient comprises isopropyl alcohol, vegetable oil, solvent naphtha, water, antifreezing agent (like propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can singly be used or and use.
Compound pesticide compositions of the present invention has good preventive effect to the multiple homoptera pest that is easy to generate resistance; And the inhibition insect is to the pesticide resistance generation of single preparation (MTI-446 or Profenofos are arbitrary).
A kind of compound pesticide compositions that contains MTI-446 and Profenofos is prevented and treated on the resistance homoptera pest insecticidal materials in preparation and is used, and especially the effect on preparation control aleyrodid, plant hopper and aphid insecticidal materials is remarkable.
Beneficial effect compared with prior art of the present invention: Pesticidal combination of the present invention can be prevented and treated the homoptera pest that takes place on the crops; Especially can be used for preventing and treating rice fulgorid, aphid etc. obvious synergistic function is arranged; Overcome and delayed pest resistance to insecticide; The expanding prevention spectrum, desinsection speed is fast, has obviously improved control efficiency; Reduce control recruitment, drug cost; Alternative high-toxic pesticide; Have concurrently quick-acting and long-acting; Compare with the agent of Profenofos list with MTI-446, produce and the use cost reduction; Suppress the resistance enhancing of homoptera pest to agricultural chemicals, its effect is used apparently higher than its single agent.
