摘要：
The present invention relates to a method of preparing a disease and insect pest control composition using an extract of Cinnamomum camphora or Sophora japonica, the method comprising powdering Cinnamomum camphora to obtain a powder of Cinnamomum camphora, mixing the powder of Cinnamomum camphora with an ethanol solvent, performing a pretreatment process of the mixture to produce an extract, separating an extracted liquid from the extract, concentrating the extracted liquid-separated extract under reduced pressure in a rotary evaporator to obtain Camphora oil, stirring Camphora oil, Cinnamon oil or Neem oil, Lemon grass oil, Eucalyptus oil and the like with a surfactant, injecting purified water and Sophora japonica extract (matrine) into the stirred material, and stirring the purified water, Sophora japonica extract (matrine) and the stirred material to prepare the disease and insect pest control composition such that the disease and insect pest control composition has antifungal effects on plant pathogenic fungi, resisting power against disease effects on strawberry flower supporting explant and lettuce leaf explant, and insecticidal effects on cabbage webworm and aphid. Further, the present invention relates to the composition which does not have a response of phytotoxicity on rust of Chionanthus retusus Lindl. & Paxton planted as a street tree, and of which an efficacy of chemicals control value reaches a level of 80%.본 발명은 녹나무를 분말화하여 에탄올용매에 혼합하여 전처리과정에서 추출물을 생성하고 이 추출물에서 추출액을 분리하여 감압농축시스템에서 감압농축한 녹나무 농축추출액(camphora oil)에 계피유(Cinnamon oil) 또는 님오일(Neem oil), 레몬그라스오일(Lemon grass oil), 유칼립투스오일(Eucalyptus oil) 등을 계면활성제와 교반하고 정제수와 회화나무추출물(matrine) 투입 및 교반하여 병해충방제 조성물을 제조하여 식물병원균에 대한 항진균효과와 딸기꽃받침절편 및 상추잎절편에 대한 항병력효과와 배추순나방에 및 진딧물에 대한 살충효과를 갖도록한 녹나무 또는 회화나무의 추출물을 이용한 병해충방제 조성물 제조방법에 관한 것이며, 더 나아가 가로수에 식재되어있는 이팝나무 녹병에 대한 약해반응은 없으면서 약효 방제가가 80%의 수준에 달하는 조성물에 관한 것이다.
