Abstract
To investigate the sensitivity of Sclerotinia sclerotiorum to novel fungicide cyprodinil, 53 isolates of S. sclerotiorum were collected from different regions in Jiangsu province of China, and tested by employing mycelial growth rate method. Results revealed significant sensitivity difference to cyprodinil among 53 isolates with EC50 ranging from 0.034 2 to 1.087 6μg/mL. Then 10 isolates with different sensitivity to cyprodinil were used for cross -resistance tests to other fungicides with diverse action mechanisms. The fungicides included carbendazim, procymi-done, iprodione, dimetachlone, tebuconazole and prochloraz. Linear regression showed that there were no positive - correlation across resistance between cyprodinil and other fungicides.关键词
