Influence of foliar spraying of SCF7, SCF11, and SCF20 on AUDPC of PVYNTN in four potato cvs. The actinomycetes’ filtrates were applied before and post virus inoculation. Variation in data shown by boxplot histogram (SPSS17). Streptomyces netropsis DSM 40093 (SCF7), Streptomyces ambofaciens (SCF11), and Streptomyces actuosus (SCF20). The disease was most severe for Diamant, less severe for Selatar, Spunta, and least for Nicola. AUDPC area under disease progress curve
