| 摘 要： | 采用菌丝生长速率法监测了1984、2001和2010年江苏省小麦纹枯病菌Rhizoctonia cerealis对井冈霉素的敏感性变化趋势,以及2010年河南、安徽和山东3省小麦纹枯病菌对井冈霉素的敏感性现状。结果表明:1984、2001和2010年江苏省小麦纹枯病菌对井冈霉素的EC50值范围分别为0.31~0.87、0.05~1.21和0.20~1.09 μg/mL,26年间江苏省小麦纹枯病菌对井冈霉素的敏感性未发生显著性变化;2010年河南、安徽和山东3省小麦纹枯病菌对井冈霉素的EC50值范围分别为0.15~1.16、0.43~0.90和0.09~1.33 μg/mL,4省小麦纹枯病菌对井冈霉素的敏感性相互间差异不显著。井冈霉素仍然可以作为防治小麦纹枯病的主要药剂。

| Abstract: | The sensitivity of Rhizoctonia cerealis populations collected in 1984,2001 and 2010 from Jiangsu Province to jinggangmycin was surveyed to monitor the trend in resistance of R.cereals,and the sensitivity of isolates collected from Shandong,Henan and Anhui Provinces were also surveyed in 2010.EC50 value of isolates in 1984 ranged from 0.31 to 0.87 μg/mL,from 0.05 to 1.21 μg/mL in 2001,and from 0.20 to 1.09 μg/mL in 2010.There was no significant difference in sensitivity of R.cerealis populations to jinggangmycin during 26 years in Jiangsu Province.EC50 value of isolates in Henan Province ranged from 0.15 to 1.16 μg/mL,from 0.09 to 1.33 μg/mL in Shandong Province,and from 0.43 to 0.90 μg/mL in Anhui Province.There was also no significant difference in sensitivity of isolates from four provinces in 2010.These results indicated that jinggangmycin can be used as major fungicide to control wheat sharp eyespot in future. |
