The silvering of tomato leaves is due to a genetic disturbance within the plant. Silver flecking on the leaves and stem is not a serious problem unless the growing point becomes affected. If all of the flowering truss is affected it will not set fruit. Later in the season as the plant develops further normal green leaves and trusses may develop.

If normal lateral shoots are being produced lower down the plant it is best to stop the plant and allow one of the green lateral shoots to develop as the main leader. If no unaffected shoots are available the growing tip of silvered shoots are best removed and the plant allowed to grow on as it may start to produce normal growth.
