Results: different extraction methods of solidago Canadensis have the effect of pesticides in the water extract, the liquid is stronger than the effect of the insecticidal effect of dilution, but with time going, gradually build up their insecticidal effect, it can achieve tou the best after 48 hours , the same stock solution of the insecticidal effect is stronger than the effect of dilution, but some time laters , the gradual weakening of the effect of insecticide 24 effect from time to time to achieve the strongest insecticide. Objective: Experimental verification of the insecticidal activity of Solidago, and based on this extract of Solidago of the insecticidal activity and extraction of the optimum conditions for exploratory research, the with hope to find a good, natural, the human body and environment-friendly and highly efficient source of plant pesticides.
