Mosaic-showing plants of Abutilon striatum “Thompsonii” can be freed from the causal virus Abutilon mosaic Geminivirus by exposing the plants to air temperatures ranging from 34 to 36 °C for several weeks. To make the plant survive the high temperature, it is advisable to give it a preconditioning treatment, such as pruning of the shoots, providing a large pot for optimal root development (to diminish the effect of water loss) and raising the temperature in the growth chamber gradually from 20 to 36 °C. Even better results may be obtained when the plant is exposed to alternating high and normal temperatures for several weeks.
