Abstract
The invention discloses a compound pesticidal composition containing ethiprole and fenvalerate and application thereof. The compound pesticidal composition uses ethiprole and fenvalerate as pesticidal active components, wherein the weight ratio of the ethiprole to the fenvalerate is (0.1-80):(0.5-80). The pesticidal composition can generate higher synergic effect, overcomes and postpones the drug resistance of pests, has the advantages of high pesticidal speed and long duration time, lowers the pesticide cost, and has obviously higher preventing and treating effects than a single agent. The composition can prevent and treat hemiptera pests on crops, especially can be used for preventing and treating rice planthoppers and aphids, and has obviously higher effect than a single agent.
Description
Technical field
The invention belongs to the field of agricultural pesticide that contains heterocyclic compound, concrete body relates to a kind of compound pesticide compositions.
Background technology
Second worm nitrile (Ethiprole), chemical name: 1-(2,6-dichlor-4-trifluoromethyl phenyl)-3-cyano group-4-ethyl sulfinyl-5-amino-pyrazol.Molecular formula is: C
13h
9c
l2f
3n
4oS.
Second worm nitrile (Ethiprole) is the Insecticidal and acaricidal agent by rhone-poulenc is found, Beyer Co., Ltd develops, belong to effective to multiple chewing type and sucking pest under the low consumption of insecticide that the second generation acts on GABA, can be used for seed treatment and foliar spray, the lasting period reaches 21-28d.(be mainly used in preventing and treating thrips, stinkbug, curculionid, beet gelechiid, aphid, plant hopper and locust etc., some aleyrodid is also shown to activity (particularly the rice grub green rice bug of extremely difficult control being had to very strong activity).
Sumicidin (Fenvalerate), has another name called: Belmark, kill chrysanthemum ester, Belmark, isoamyl Cyano chrysanthemate, Belmark.Chemical name is: (R, S)-alpha-cyano-3-benzyloxy phenoxy base (S)-2-(4-chlorphenyl)-3 Methylbutanoic acid ester, and structural formula is:
Sumicidin is the pyrethroid insecticides of high-efficiency broad spectrum, and insecticidal spectrum is wide, to natural enemy non-selectivity, take and tags with stomach poison function as main, without interior suction conduction and fumigation action.Effective to lepidopterous larvae, the insects such as Semiptera, orthoptera, Semiptera are also had to better effects, invalid to mite class.And the volume increase of crop and promotion precocity are had certain effect.To people, animal moderate toxicity.
But rice fulgorid and aphid are 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 second worm nitrile and sumicidin.
Summary of the invention
The object of this invention is to provide a kind of compound pesticide compositions containing second worm nitrile and sumicidin, this Pesticidal combination is the multifunctional insecticide composition of control Semiptera insect.
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 Semiptera insect, particularly the application on the insecticidal materials of preparation control plant hopper, aleyrodid or aphid.
The object of the invention is to be achieved through the following technical solutions:
Containing a compound pesticide compositions for second worm nitrile and sumicidin, it is active insecticidal components that this compound pesticide compositions be take second worm nitrile and sumicidin, and wherein, the weight ratio of second worm nitrile and sumicidin is 0.1 ~ 80:0.5 ~ 80.
In this compound pesticide compositions, the weight ratio of second worm nitrile (A) and sumicidin (B) is preferably 0.5 ~ 50:1 ~ 50.A kind of preferred scheme is that the two weight ratio of A and B is further 0.5 ~ 10:1 ~ 30, most preferably is 1～10:1～10.It is that the two weight ratio of A and B is 0.1～20:1 that another kind is preferably scheme, is further 0.1～10:1.
This compound pesticide compositions can only contain active component second worm nitrile and sumicidin, also can when using or prepare, in active component, add other components, and the effective ingredient in this Pesticidal combination can also synergy effective dose be present in composition.
In compound pesticide compositions of the present invention, the two weight percentage in this compound pesticide compositions of second worm nitrile and sumicidin is 3 ~ 80%.Be preferably 5 ~ 55%, most preferably 10 ~ 40%.
It is active component or main active ingredient that Pesticidal combination of the present invention be take second worm nitrile and sumicidin, be mixed with insecticides adjuvant and excipient any one formulation allowing on agricultural chemicals, described formulation is preferably missible oil, suspending agent, wetting powder, aqueous emulsion, microemulsion or water dispersion granule.
Aforementionedly can be applicable to the not special restriction of insecticides adjuvant of the present invention, include, but are not limited to calcium dodecyl benzene sulfonate, 600#, the rare block compound of polyoxyethylene polyoxy third (as agriculture breast 33
#), polyoxyethylene nonylphenol ether etc.Aforementionedly can be applicable to excipient of the present invention and be also not particularly limited, include, but are not limited to 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 Semiptera insect that Pesticidal combination of the present invention easily produces resistance to rice fulgorid and aphid etc. has good preventive effect; And suppress insect the pesticide resistance of unitary agent (second worm nitrile or sumicidin are arbitrary) is produced.
Above-mentioned Pesticidal combination is prevented and treated the application on the insecticidal materials of resistance Semiptera insect in preparation, especially the effect on the insecticidal materials of preparation control aleyrodid, rice fulgorid or aphid is remarkable.
Beneficial effect of the present invention compared with prior art: (1) is compared with single dose, said composition antagonism Semiptera insect, 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 sumicidin single dose with second worm nitrile, produce and use cost reduction; (6) suppress Semiptera insect the resistance of agricultural chemicals is strengthened, its successful is used higher than its single dose.
