Abstract
Penicillium claviforme Bainier culture filtrate (PCF) contained metabolites antagonistic to the mycelial growth of Pythium ultimum Trow in vitro. PCF extract incorporated into sugar beet (Beta vulgaris) seed pellets had no effect on seedling emergence in peat-based compost and significantly improved both emergence and establishment in compost artificially-infested with P. ultimum. Although PCF was less effective than the synthetic fungicide hymexazol in reducing a high incidence of disease, the performance of the two agents in suppressing a milder pre-emergence infection was not significantly different. The half-life of the anti-Pythium components of PCF in the seed pellets was ca 14 months. It is concluded that antagonistic fungal metabolites incorporated into seed pellets have potential as natural fungicides in the control of Pythium-induced seed and seedling diseases. © 1989.
