Background : This experiment was carried out to investigate the occurrence of disease and pest and the yield depending on cultivation methods in Cynanchum wilfordii. Methods and Results : There were damages by anthracnose, aphid, mite, thrips, Gastrophysa atrocyanea, Tropidothorax cruciger and Metcalfa pruinosa. In the case of anthracnose, the number of damaged leaf in the untreated control plot per counting area (67.5 ㎡) was 8.6 times higher than that of chemical treated plot. As a result of investigation of shoot damage and leaf juice damage by Tropidothorax cruciger, which made the most obvious damage symptom, showed the significantly lower degree of damage in the treatments of insecticides (abamectin, suloxac flour liquid wettable powder). In addition to the pest damage, the yield of roots was investigated. As a result, it was found that the yields were 3.8 ㎏, 2.6 ㎏, 1.7 ㎏ and 1.4 ㎏ per 8.5 ㎡ respectively in vine scheme cultivation with chemical control, vine scheme cultivation with non-chemical control, non-vine scheme cultivation with chemical control and non-vine scheme cultivation with non-chemical control. Conclusion : The yield per 1,000 ㎡ was 449 ㎏, which was 1.9 times higher than the national average of three years in vine scheme cultivation with chemical control.
