I seem to recall being informed that farmers use a herbicide on the tops of
potato's to stop any further top growth, and leave tubers in ground for
storage.
Is this still the practice?

Yes - it's to prevent blight from getting into the tubers. But it
worn't do any harm, as it's only sulphuric acid - which is volatile,
won't affect the tubers, and wouldn't matter anyway!
