对橡胶树白粉病菌的3种接种方法一抖粉法、涂抹法和喷雾法进行比较,并测定了喷雾法不同接种量对橡胶白粉病病情指数和10 mg/L三唑酮相对防效的影响.结果表明,喷雾法较抖粉法和涂抹法重复性更好,结果更稳定;在进行杀菌剂对橡胶树白粉病菌的室内盆裁毒力测定时,应采用喷雾法,接种童以5×10(4)～10×10(4)个/mL 为宜.%A comparison of different inoculation methods, including spraying, shaking-off and brushing of spores,was conducted, and variation of disease index and control effect of 10 mg/L triadimefon on Oidium heveae were detected at different inoculation concentrations. It is suggested that the inoculation method, spraying spores at the concentration of 5 × 104- 10 × 104 spores/mL, brought the most stable and repeatable results.
