Abstract
POTATO virus X is well known as a source of loss to the potato industry, and schemes exist to protect newer varieties from contamination. In most countries there remain in use— often in favour–varieties that are saturated with virus X. In Australia the varieties Brownell, Carman and Delaware are in this class. To free such a variety from virus X by chemotherapy would be a significant economic advance. It would also be of importance to the general problem of plant virus control by demon- strating that, even with a stable, mosaic-type virus like potato X, there is a sufficient difference between the biosynthetic processes of the virus and of the host to make selective chemical therapy a real possibility.
