The fungicide sensitivity of more than 450 isolates of Sclerotium rolfsii from 11 different peanut fields in Georgia was determined based on percent inhibition of mycelial growth on agar amended with tebuconazole, flutolanil, or PCNB. The 11 locations represented a wide geographic distribution and variety of exposure histories to tebuconazole, flutolanil, and PCNB. Most of the populations sampled were significantly more sensitive than the populations that had the longest exposure to the fungicides. Of the three fungicides tested, tebuconazole and flutolanil demonstrated the strongest positive correlation in 1994 and 1995. The differences in sensitivity among locations suggest that fungicide sensitivity among S. rolfsii populations varies across Georgia. The location with the longest exposure history had the lowest sensitivity to all three fungicides.
基于在添加戊唑醇、氟酰胺或五氯硝基苯的琼脂上菌丝体生长的抑制百分比，测定了来自佐治亚州11个不同花生田的450多个立枯丝核菌分离株对杀菌剂的敏感性。这11个地点代表了广泛的地理分布以及对戊唑醇、氟酰胺和五氯硝基苯的各种接触历史。大多数采样群体比接触杀菌剂时间最长的群体对杀菌剂明显更敏感。在1994年和1995年测试的三种杀菌剂中，戊唑醇和氟酰胺表现出最强的正相关性。不同地点之间的敏感性差异表明，佐治亚州立枯丝核菌群体之间的杀菌剂敏感性各不相同。接触历史最长的地点对所有三种杀菌剂的敏感性最低。
