20.500.12556/RUL-111394 Preizkušanje učinkovitosti glive Coniothyrium minitans W.A. Campb. na sklerocijih različnih patogenih gliv Testing the efficiency of fungus Coniothyrium minitans W.A. Campb. on sclerotia of different pathogenic fungi Hiperparazitska gliva Coniothyrium minitans, ki je naravno prisotna v tleh, najbolje raste pri temperaturi 20 °C. Z nižanjem ali višanjem temperature se njena rast in aktivnost zmanjšujeta. Na njeno uspešno rast micelija ne vpliva prisotnost patogena, ampak je prav temperatura eden ključnih dejavnikov za optimalno rast in uspešno parazitiranje sklerocijev patogenih gliv. Z inokuliranjem sklerocijev šestih izbranih patogenih gliv Sclerotinia sclerotiorum, Sclerotinia minor, Botrytis sp., Macrophomina phaseolina, Sclerotium rolfsii in Sclerotium cepivorum, pri treh različnih temperaturah (15, 20, 25 °C) v laboratorijskih pogojih smo ugotovili, da se uspešnost parazitiranja sklerocijev istega patogena s strani glive C. minitans razlikuje glede na temperaturo. Ne parazitira uspešno vseh patogenov in ne vsakega enako pri različnih pogojih. Potrdili smo, da je gliva C. minitas uspešen parazit sklerocijev gliv iz rodu Sclerotinia in bi se lahko tudi pri nas uporabljal kot učinkovit biotični agens. Hyperparasitic fungus Coniothyrium minitans, naturally present in the soil, grows best at temperature 20 °C. By lowering or increasing the temperature, its growth and activity decrease. Successful growth of the mycelium is not affected by the presence of the pathogen. Temperature is one of important factors for optimal growth and successful parasitizing of sclerotia of pathogenic fungi. By inoculating the sclerotia of six selected pathogenic fungi Sclerotinia sclerotiorum, Sclerotinia minor, Botrytis sp., Macrophomina phaseolina, Sclerotium rolfsii and Sclerotium cepivorum, at three different temperatures (15, 20, 25 °C) under laboratory conditions, we confirmed that the success of parasitizing sclerotia of the same pathogen by C. minitans varies with temperature. It does not successfully parasitize all pathogens and not all equally under different conditions. We have confirmed that C. minitas is a successful parasite of the genus Sclerotinia and could also be used as an effective biological control agent.
