This study was carried out to control the disease of wood-cultivated ginseng(panax ginseng) using natural materials. Four fungi spices such as Pythium ultimum, Alternaria alternata, Fusarium oxysporum and Rhizoctonia solani which caused disease of the wood-cultivated ginseng were investigated. The infection of these fungi causes symptom on roots, stems and leaves. The leaves became dry and die. The disease caused by Pythium ultimum can be prevented by using friendly environmental materials like Chamaecyparis obtuse essential oil and Wormstop. Alternaria alternata and Fusarium oxysporum might be prevented by using wormstop extracted from Neem tree(Azadirachta indica). No substance tested effectively prevents the growth of Rhizoctonia solani.

A study was carried out to identify the life cycle of Adoxophyes orana (Lepidoptera: Tortrididae) that inflicts tea tree leaves in Korea and selected three ecofriendly pesticides (Common name for commercial: Essential oil, Nemacatch, and Wormstop in Korean Farmers' Market) of A. orana for pest control. A. orana appeared to follow four life cycle phases a year; each presenting varying developmental periods dependent on seasonal and environmental factors. The fecundity of A. orana female was $24.6{\pm}4.10$ for $1^{st}$, $36.7{\pm}12.77$ for$ 2^{nd}$, and $27.9{\pm}4.22$ for $3^{rd}$ phase during 2011, while it was $65.0{\pm}32.72$, $49.7{\pm}30.27$, $63.8{\pm}27.22$ for corresponding phases during 2012. The average longevity of adult A. orana was 7.72 days. The average number of eggs deposited by each female in this study group was 44.62 with an average of 2.47. In three selected ecofriendly pesticides, the mortality of A. orana on treating with the Essential oil [The essential oil of Chamaecyparis obtuse (100%)] and Nemacatch [Azadirachtin 800-900 ppm (75%)] were 36.67% and 43.33% after 3 days and were 48.30% and 56.67% after 7days, respectively. Besides, the mortality of A. orana on treating with Wormstop [Azadirachtin 500 ppm (5%) and Salannin+Liminoids (95%)] was 61.67% and 78.33% after 3 and 7 days, respectively. Therefore, the application of Wormstop was the most useful to control the diseases caused by A. orana.

본 연구는 밤 종실을 생산량과 소득증대를 위한 방제 기술을 보급하고자 밤의 주 생산지인 경상남도 밤나무 집단 재배지에서 몇 가지 친환경적인 방법으로 처리한 결과를 요약하면 다음과 같다. 복숭아명나방(Dichocrocis punctiferalis)의 피해율은 조생종인 단택과 삼조생 밤이 웜스톱 처리구에서 피해율이 8.17%로 가장 낮았고, 포충기, 네마캐치, 나프탈렌 처리구 순이었다. 중생종인 유마와 축파 밤은 웜스톰 처리구에서 9.83%로 가장 낮았으며 피해율간 유의차가 있었다(p<0.05). 만생종인 박미와 은기 밤은 피해율간 유의차가 없었다(p>0.05). 처리별 방제가는 조생종, 중생종 밤의 웜스톱 처리구에서 각각 90.68%, 80.58%로 가장 높았다. 밤바구미(Curculio sikkimensis)의 피해율은 조생종과 중생종 밤에서는 피해율이 낮았으며, 처리별 피해율간의 유의차가 없었다(p>0.05). 만생종 밤에서 피해율은 네마캐치 처리구가 13.07%로 가장 피해율이 낮았으며, 웜스톱, 포충기, 나프탈렌 처리구 순이었다. 밤바구미(Curculio sikkimensis)에 대한 처리별 방제가는 조생종과 중생종에서는 처리간 유의차가 없었고, 만생종의 네마캐치와 웜스톱 처리구에서 방제가는 각각 80.58%, 77.90%였다.
