| 中文摘要: |
| 由致病性链格孢引起的叶枯病是栝蒌生产上出现的一种新病害, 在安徽大别山栝蒌生产区发生严重。本研究采用菌丝生长速率法测试了12个代表性栝蒌叶枯病菌菌株对4种常用杀菌剂的敏感性。结果表明, 栝蒌叶枯病菌对咪鲜胺敏感性较高, 其EC50为0.013 0~0.219 μg/mL; 代森锰锌和百菌清对栝蒌叶枯病菌均有一定的抑制作用, 但各菌株对代森锰锌和百菌清的敏感性差异较大, 其EC50分别为0.997~95.64 μg/mL和1.66~185.84 μg/mL; 多菌灵对栝蒌叶枯病菌的菌丝生长抑制作用较差。 |
| 英文摘要: |
| A new leaf blight disease caused by Alternaria alternata was observed and reported on Trichosanthes kirilowii Maxim. in the southwest region of Anhui Province, which has become a serious disease limiting snakegourd fruit production in recent years. 12 representative strains of A. alternata were isolated from T.kirilowii plants in different farms, and the sensitivities of 12 strains to 4 fungicides were measured by the mycelial growth rate method. The results showed that the isolates were sensitive to prochloraz with the EC50 values of 0.013 0-0.219 μg/mL.Mancozeb and chlorothalonil had certain inhibitory effects on the growth of A. alternata, with the EC50 values of 0.997-95.64 μg/mL and 1.66-185.84 μg/mL, respectively, while there were variations in sensitivities to the same fungicide among isolates from different areas. Moreover, the isolates were less sensitive to carbendazim. |
