Hockenhull J. pub 8planthealth fruit growing, Venturia inaequalis, disease, Yucca, potassium bicarbonate Efficacy of compounds was investigated in field experiments in Denmark and the Netherlands according to EPPO guidelines. Some Yucca extracts and potassium bicarbonate had an efficacy similar to sulphur on leaves. Addition of sulphur to Yucca 1 and to potassium bicarbonate increased the level of efficacy to that of copper. This confirms results from earlier years. Although a dose increase resulted in better efficacy, this was more prominent for Yucca1 than for potassium bicarbonate. 2007 published public 7003 1 9449 1 application/pdf de public
