The susceptibility of black currant cultivars to leaf spot caused by Pseudopeziza ribis Kleb

, : The susceptibility of black currant cultivars to leaf spot caused by Pseudopeziza ribis Kleb. Acta Horticulturae (60): 205-213

Of the numerous cvs studied, Blacksmith was the least affected by P. ribis, followed by Amos Black, Baldwin, Cotswold Cross, Malvern Cross and Wellington XXX. The highest yields were obtained from Mendip Cross followed by Blacksmith and Malvern Cross. The results for all other cvs are tabulated.

Excellent control of Paeudopeziza ribis, the cause of black currant leaf spot, was obtained on a plot of 4.3 acres of the Baldwin variety by spraying on 20th July (immediately after picking) with 4-4-50 or 2-4-50 Bordeaux mixture, applied "by...

Additional spraying after picking increased yiel...
