The effect of tuber dressing and plant spraying with Polyversum (B.A.S. Pythium
oligandrum) and Biochikol 020 PC (B.A.S. chitosan) bio-preparations on the
infestation of potatoe tubers by Streptomyces spp. was studied during the
2005–2007 years. The Vitavax 2000 FS (B.A.S. karboxin and thiuram) was used as
a standard fungicide.
The results received from field experiments indicate that, during all years of
study these preparations significantly reduced tubers infestation by Streptomyces
spp. The Polyversum bio-preparation, which was applied to tuber dressing and
sprayed on plants four times during vegetation period, showed the best protective
effect against Streptomyces spp.
