| 摘 要： | 采用菌丝生长速率法,在室内分别测定了啶酰菌胺(Boscalid)、井冈霉素(Jinggangmycin)和己唑醇(Hexacon-azole)对水稻纹枯病菌(Rhizoctonia solani Kühn)的毒力,并进行了田间防治试验。结果表明:啶酰菌胺、井冈霉素和己唑醇对水稻纹枯病菌菌丝生长抑制的EC50值分别为1.0692、96.2859和0.0240μg/mL;50%啶酰菌胺WDG 600倍液在第2次药后14 d对田间水稻纹枯病的防效为63.53%,极显著低于对照药剂20%井冈霉素A WP 1500倍液和5%己唑醇SC 600倍液的防效。

| Abstract: | Mycelium growth rate method was used to determine the indoor virulence of Boscalid,Jinggangmycin and Hexaconazole against Rhizoctonia solani Kühn,and these fungicides were also applied to control rice sheath blight in the field.The results showed that the EC50 values of Boscalid,Jinggangmycin and Hexaconazole were 1.0692,96.2859 and 0.0240 μg/mL,respectively.On the 14th day after the second spraying,the control efficiency of 50% Boscalid WDG 600-times dilute solution against rice sheath blight was 63.53%,which was significantly lower than that of the control fungicides 20% Jinggangmycin A WP 1500-times and 5% Hexaconazole SC 600-times dilution. |
