Wildfire of black currants

, : Wildfire of black currants. Acta Horticulturae: 85-89

The disease is one of the most widespread of those affecting blackcurrants throughout Siberia and the Far East, causing up to 25% losses in yield. Leaf symptoms are evident in mid-May as diffused light green spots which coalesce to produce large areas of chlorosis. Rings and elongated streaks occur along the main veins and heavy infection results in reduced leaf size and abnormal leaf formation. Infection increases during the season to reach a peak in Sept.
