Ficus Carica Linn Stem Extract Extraction And Myzus Persicae (Sulzer) Control Effect Research

Extract from plants which have a biological insecticidal activity substance, as synthetic plantsource pesticide research foundation, is the natural plant source of pesticide in development andutilization of a hot issue. Myzus persicae (Sulzer) is our country is my area of one of the importantpests, through the extraction Ficus carica with insecticidal activity material for prevention andtreatment of aphids, find the right of the prevention and control of persicae (Sulzer) agent formula.This thesis to Myzus persicae (Sulzer) for the insect, the dipping method with3kinds of Ficuscarica Linn extracts to peach aphid indoor virulence measurement, prove the Ficus carica Linn containswith insecticidal activity substances, including acetone extract contained in the material has a stronginsecticidal activity, followed by ethyl acetate, and ethanol extract of persicae (Sulzer) insecticidalactivities the most weak, through chemical composition prediction try, to the Ficus carica Linn stemextract in the specific what kind of chemical composition on the preliminary appraisal, the test resultsshow that contain alkaloids, phenol sexual material, terpenoids and steroid compound, such as brass.This experiment with normal butanol, chloroform, ethyl acetate, petroleum ether as extractionsolution, and the results show that the normal butyl alcohol extract of peach aphid insecticidal activity t.urticae highest reached38.16mg/L, followed by ethyl acetate and chloroform, respectively131.63mg/L and72.19mg/L, and petroleum ether insecticidal activities the most weak as high as875.03mg/L.Can be used as the plant source of pesticide in extract use. Thus it can be seen, n-butanol as extract isalso very good.This chapter through the different solvent to the Ficus carica Linn concrete solution, determine theoptimum solvent of acetone as the main solvent,95%alcohol as cosolvent, choose different emulsifierto emulsify, through the physical properties, emulsification stability and determination, choosing themost suitable and emulsifier op13, etc.Through the solvent, emulsifier and formula,40%final Ficus carica Linn extract as formula agentsto persicae (Sulzer) indoor virulence measurement and field efficacy trials, the experimental resultsshow that, although although40%Ficus carica Linn extract and10%imidacloprid control effect has acertain gap, but it has some insecticidal effect, it still need further experiment research, choose a moresuitable solvent, emulsifier, synergistic agent, etc.This test just Ficus carica Linn extracts agent test, but in practical application, as to what kind ofdosage form can have better control effect, still need further research and exploration.
