Abstract
The invention discloses a composite insecticidal composition containing dinotefuran and isoprocarb and purpose thereof. The insecticidal composition contains main effective components of dinotefuran and isoprocarb in a mass ratio of 0.1-80:0.5-80. The insecticidal composition can generate high synergism, overcome and delay resistance of insect, has fast insecticidal speed, long persistent period, reduced drug usage cost and obvious better control effect than that of a single dose. The composition of the invention can control homoptera insects on crops, especially rice hopper and aphid, and has obvious better control effect than that of a single dose.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of compound pesticide compositions containing MTI-446 and Mobucin 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, and to quail acute oral LD50 > 1000mg/kg., through honeybee test is learnt, MTI-446 is to honeybee safety, and do not affect honeybee producting honey.This medicament insecticidal spectrum is wide, has remarkable interior suction osmosis, and has 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.
Mobucin, chemical name: methylamino formic acid-2-isopropyl phenyl ester, molecular formula: C
11h
15nO
2, structural formula is:
Mobucin is the insecticide that a kind of tagging property has the carbamate of systemic action concurrently.Quick-acting, but the drug effect phase is very short.Be mainly used in preventing and treating rice leafhopper, cotton leafhopper and rice fulgorid etc., and can doublely control thrips, also can prevent and treat other pests with chewing mouthparts.Very little on Natural Spider Enemies impact, the lasting period is shorter.Harmful to honeybee.Under general concentration, to crop safety, but taro is had to poisoning.Should not execute with alkaline agricultural chemicals is mixed, can not use with Stam F-34 simultaneously, can 10 days above uses the in interval.
But the insect such as rice fulgorid, aphid is under the condition of current long-term prescription, and resistance increases gradually, and agricultural chemicals single dose declines gradually to the effect of control of insect.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 Mobucin.
Summary of the invention
The object of this invention is to provide a kind of compound pesticide compositions containing MTI-446 and Mobucin, 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 in preparation, prevents and treats the application on the insecticidal materials of resistance homoptera pest, particularly the application on the insecticidal materials of preparation control plant hopper, aphid.
The object of the invention is to be achieved through the following technical solutions:
Containing a compound pesticide compositions for MTI-446 and Mobucin, it is main active ingredient that this Pesticidal combination be take MTI-446 and Mobucin, and wherein, the weight ratio of MTI-446 and Mobucin 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 synergy effective dose.
In compound pesticide compositions of the present invention, the two weight percentage in this compound pesticide compositions of MTI-446 and Mobucin is 3%～80%.Be preferably 5%～55%, most preferably 10%～40%.
Compound pesticide compositions of the present invention be take MTI-446 and Mobucin and is mixed with any one formulation allowing 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 solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can alone or and use.
Multiple Homoptera and lepidoptera pest that compound pesticide compositions of the present invention easily produces resistance to rice fulgorid and snout moth's larva etc. have good preventive effect; And suppress insect the pesticide resistance of unitary agent (MTI-446 or Mobucin are arbitrary) is produced.
Above-mentioned compound pesticide compositions is prevented and treated the application on resistance homoptera pest insecticidal materials in preparation, and especially the effect on preparation control plant hopper or aphid insecticidal materials is remarkable.
Beneficial effect of the present invention compared with prior art: (1) is compared with single dose, said composition antagonism homoptera pest, as rice fulgorid, aphid etc. has obvious synergistic function, 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 Mobucin single dose with MTI-446, produce and use cost reduction; (6) suppress homoptera pest the resistance of agricultural chemicals is strengthened, its successful is used higher than its single dose.
