영어
Disease management of oak wilt, mainly occurred in Quercus mongolicae by Raffaelea quercus-mongolicae in Korea, have been mainly focused on the control of insect vector(Platypus koryoensis) by treatments of insecticide spray, pheromone trap, sticky roll trap, and fumigation of dead or dying trees. For the control the pathogen colonized in trees, culture suspension of antifungal Streptomyces blastmyceticus was injected into trees in the forest by trunk (ChemJet®) or root flare(Macro-infusion) injection methods before or after pathogen inoculation, and the ratios of non-conductive area, discolored area, and re-isolation of the pathogen from the treated trees were calculated for evaluating preventive or curative efficacy. Injection of S. blastmyceticus or the fungicide(Alamo®) showed 41.7% and 45.8% in non-conductive area(%), respectively. In addition, S. blastmyceticus did not show much differences between injection methods and timings in control effect, but fungicide treatment was better in Macro-infusion at root flare or curative treatments. Re-isolation rates of the pathogen in the pathogen only, preventive and curative treatments were 56.9%, 20.6%, and 36.1%, respectively. These results indicate that S. blastmyceticus has better control efficacy than the fungicide commercially available for the control of oak wilt caused by Ceratocystis fagacearum in the United States.
