The present invention relates to a fast-acting natural insecticidal composition containing a plant extract as an active ingredient. More specifically, the present invention relates to a fast-acting natural insecticidal composition having an insecticidal function rapidly applied to insects which are harmful to farms and containing a plant extract which is not harmful to the natural environment and the human body as an active ingredient, wherein the fast-acting natural insecticidal composition comprises 20.5-68.9 wt% of a Sophora root extract, 2.0-8.0 wt% of neem oil, 5.0-15.0 wt% a Solanum nigrum extract, 2.0-8.0 wt% a Kochiae Fructus extract, 2.0-8.0 wt% of a surfactant, 0.1-0.5 wt% of xanthan gum, and 20.0-40.0 wt% of water. Moreover, the present invention provides a method for producing a fast-acting natural insecticidal composition, the method comprising the steps of: (S1) mixing neem oil with a surfactant, and emulsifying a mixture; (S2) feeding and agitating a Sophora root extract in the mixture produced through the step S1; (S3) mixing a Solanum nigrum extract and a Kochiae Fructus extract; (S4) feeding and dispersing xanthan gum in a mixture produced through the step S3; and (S5) feeding and agitating water and a mixture produced through step S4 in the mixture produced through step S2. Accordingly, a fast-acting natural insecticidal composition using a plant extract according to the present invention may be used to harmful insects which significantly damage farms, does not have chemical damage, and has a rapid insecticidal effect. |
