Dematophora necatrix, the causal agent of the white root rot disease in plants, produced large amounts of cellulase (Cx) and very small amounts of polygalacturonase (PG). Both tannins (100 mg/l) and phenols (200 mg/l) extracted from roots of plants showing resistance to the disease decreased Cx production in vitro. PG production was affected only by tannin extracts. Exposure of the fungus for 2 days to the tannin (100 mg/l) but not to the phenol (200 mg/l) extracts decreased the subsequent rate of fungal growth in an agar medium free of these compounds. © 1989 Springer Science + Business Media B.V.
