摘　　要：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10mg／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；在进行杀茵剂对橡胶树白粉病菌的室内盆栽毒力测定时，应采用喷雾法，接种量以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 5×10^4～10×10^4 spores/mL, brought the most stable and repeatable results.
