In this study, RT-LAMP was proven to be able to detect CCCVd from oil palm leaf samples. RT-LAMP was reported to be efficient indetecting other viroids such as Potato spindle tuber viroid (PSTVd) and Peach latent mosaic viroid (PLMVd) Detection of PSTVd required a temperatureof 65◦C for 30 min, whereas PLMVd was detected at 62.5◦C after30 min incubation. A temperature of 60◦C was found optimal fordetecting CCCVd from oil palm samples within 1 h, in accordancewith previous studies which showed that temperatures in the 60–65◦C range are the optimum for Bst DNA polymerase
