Abstract
The invention discloses a composite insecticidal composition containing pyridalyl and dimehypo and a use thereof. The composite insecticidal composition contains pyridalyl and dimehypo as active insecticidal components and a weight ratio of pyridalyl to dimehypo is 0.1-80: 0.5-80. The composite insecticidal composition can produce good synergism, overcomes and delays insect resistance to pesticides, has a fast insecticidal rate and a long persistent period, reduces a pesticide cost and has prevention and control effects obviously higher than that of a single-ingredient pesticide. The composite insecticidal composition can prevent and control lepidoptera pests of crops, especially can be used for preventing and controlling cotton bollworm and stem borers and has effects obviously higher than that of a single-ingredient pesticide.
Description
Technical field
The invention belongs to pesticide field, be specifically related to that a kind of to be principle active component with fluoroform pyrrole ether and dimehypo kill
Worm composition and application thereof.
Background technology
Fluoroform pyrrole ether (Pyridalyl), chemical name: 2-{3-[2.3-bis-chloro-4-(3,3-bis-chloro-2-acrylic oxygen base) phenoxy group] propoxyl group }-5-(trifluoromethyl) pyrimidine, structural formula:
Fluoroform pyrrole ether, also known as pyridalyl, is to be developed by SUMITOMO CHEMICAL chemical company and the novel pyrimidines developed is efficient, low toxic pesticide, has remarkable preventive effect, with existing lepidopteran insecticidal agent without cross resistance to lepidoptera pest.It has the effect of tagging with stomach toxicity, is mainly used in the lepidoptera pest larva preventing and treating damage to crops, also has good preventive effect in addition to thrips thrips, diptera leaf miner.
Dimehypo (Bisultap), molecular formula: C
5h
11o
6nS
4na
2, chemical name: the two thiosulfonic acid sodium base propane of 2-dimethylamino-1,3-.
Dimehypo belongs to nereistoxin insecticides, is a kind of never poison, insect contact and show after taking food medicament blunt, slow in action, lose that the infringement ability of crop, stasi, polypide are softening, paralysis is until dead.Dimehypo has very strong systemic action, can be absorbed and conduction by the leaf of crop, root etc.To insect, there is stronger tagging and stomach poison function, and have certain fumigation action concurrently.There is very strong systemic action, can be absorbed and conduction by the leaf of crop, corn, root etc.Be applicable to the crops such as paddy rice, vegetables, fruit tree, cotton and wheat.
But the insect such as cotton bollworm, snout moth's larva is under the condition of current long-term prescription, resistance increases gradually, and the effect of agricultural chemicals single dose to control of insect declines gradually.Inventor finds after deliberation, and the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures improving preventive effect, not yet finds the Pesticidal combination about fluoroform pyrrole ether and dimehypo up to now.
Summary of the invention
The object of this invention is to provide a kind of compound pesticide compositions containing fluoroform pyrrole ether and dimehypo, this Pesticidal combination is the multifunctional insecticide composition of control lepidoptera pest.
Another object of the present invention is to provide this Pesticidal combination and is preparing the application prevented and treated on the insecticidal materials of resistance lepidoptera pest, the application particularly on the insecticidal materials preparing control cotton bollworm or snout moth's larva.
The object of the invention is to be achieved through the following technical solutions:
Containing a compound pesticide compositions for fluoroform pyrrole ether and dimehypo, this compound pesticide compositions is with fluoroform pyrrole ether and dimehypo for principle active component, and wherein, the weight ratio of fluoroform pyrrole ether and dimehypo is 0.1 ~ 80:0.5 ~ 80.
In this compound pesticide compositions, the weight ratio of fluoroform pyrrole ether (A) and dimehypo (B) is preferably 0.5 ~ 10:1 ~ 30, and more preferably 1 ~ 10:1 ~ 10, most preferably are 1 ~ 10:1.
This compound pesticide compositions can only containing active component fluoroform pyrrole ether and dimehypo, and also can add other components when using or prepare in active component, the effective ingredient in this Pesticidal combination can also be present in composition by enhancing effective amount.
In compound pesticide compositions of the present invention, both fluoroform pyrrole ether and the dimehypo weight percentage in this compound pesticide compositions is 3% ~ 80%.Be preferably 5% ~ 55%, further preferably 20% ~ 55%, most preferably 20% ~ 30%.
Compound pesticide compositions of the present invention with fluoroform pyrrole ether and dimehypo for active component or principle active component, any one formulation that agricultural chemicals allows is become, the preferred missible oil of described formulation, suspending agent, wetting powder, aqueous emulsion, microemulsion or water dispersion granule with insecticides adjuvant and excipient.
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, agriculture breast 600
#, the rare block compound of polyoxyethylene polyoxy third is (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 solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can be alone or and use.
Compound pesticide compositions of the present invention has good preventive effect to the multiple Semiptera of the easy generation such as cotton bollworm and snout moth's larva resistance and lepidoptera pest; And suppress insect to produce the pesticide resistance of unitary agent (fluoroform pyrrole ether or dimehypo arbitrary).
Compound pesticide compositions of the present invention can prepare the application prevented and treated on resistance lepidoptera pest insecticidal materials, and the effect especially on preparation control cotton bollworm or snout moth's larva insecticidal materials is remarkable.Described snout moth's larva is preferably rice-stem borer.
Compared with prior art beneficial effect of the present invention: (1) is compared with single dose, said composition antagonism lepidoptera pest is obvious synergistic function as cotton bollworm, snout moth's larva etc. have, and overcomes and has delayed pest resistance to insecticide, and expanding prevention is composed, desinsection speed is fast, significantly improves control efficiency; (2) control recruitment, drug cost is reduced; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) with fluoroform pyrrole ether compared with dimehypo single dose, produce and use cost reduction; (6) suppress lepidoptera pest to strengthen the resistance of agricultural chemicals, its successful uses higher than its single dose.
