Baseline Sensitivity and Monitoring for the Resistance to Benomyl of Fusarium Species Causing Bakanae Disease in Korea Choi, Hyo-Won; Lee, Yong Hwan; Hong, Sung Kee; Lee, Young Kee; Lee, Jae Guem; Kim, Hyo Won;
To examine the changes in resistance to benomyl of Fusarium species causing bakanae disease, Fusarium isolates were collected in Korea, and pathogenicity tests were performed using rice seeds in vitro. Minimum inhibitory concentration (MIC) and effective concentration of 50% () values of isolates were examined using the agar dilution method. High frequency distribution of MIC values to benomyl against isolates collected in 2006~2007 and 2013~2014 years were and more than , respectively. The mean value of isolates to benomyl increased from in 2006~2007 to in 2013~2014. Based on MIC and values of isolates, the moderate resistance of benomyl were determined as more than of MIC and less of value, and resistant isolates to benomyl were determined as more than of value. Compared with the ratio of resistant isolates in 2006~2007, the ratio of resistance isolates in 2013~2014 increased from 12.5% to 36.4%. In addition, multiple resistant isolates to prochloraz as well as benomyl increased to 20.3% in 2013~2014.
