Annotation
Metabolism products of entomopathogenic nematode symbiotic bacteria (Xenorhabdus, Enterobacteriaceae) were tested against Fusarium dry rot (Fusarium spp.)at tuber storage of field contaminated Solanum tuberosum Lpotato. The tubers for the experiment were taken 5 days after harvesting. The storage temperature was of 2–3°C, relative air humidity — 80–90%. For the assessment of the biological efficiency the methods of phytopathology and the methods recommended for fungicide tests in potato protectionagainst disease were used. Maxim chemical preparation(suspension concentrate, SC) was used as an etalon. The results showed that application of metabolism products of entomopathogenic nematode symbiotic bacteria for 3–8 months suppressed Fusarium dry rot by 81.5–75.3%(Maxim chemical etalon, SC –77.8–76.7%).Combined application of metabolism products of entomopathogenic nematode symbiotic bacteria and MaximSC proved to be highly effective (biological efficiency – 100%). Theirtank mixtureis shown to be used to suppress Fusarium dry rot effectively. The results confirm perspectives of metabolism products of entomopathogenic nematode symbiotic bacteria for potato protection against Fusarium dry rot at storageas an alternative to Maxim SC fungicide.
