Relationship between initial oospore number of Pythium oligandrum, mode of the mycoparasite application and population
dynamics of Fusarium oxysporum f.sp. dianthi and development of Fusarium wilt of carnation was studied. Mixing of
oospores with peat 10 days before carnation planting resulted in strong inhibition of the pathogen development. Number
of colony forming units of the pathogen decreased at least 3 times. Application of P. oligandrum resulted in suppression
of Fusarium wilt development, especially when the mycoparasite was applied at dose 100 oospore/g of peat.
