Einsatz von Chitin als Bodenverbesserungsmittel gegenPyrenochaeta lycopersici

The severity of infection of tomato plants (cv. De Berao) by Pyrenochaeta lycopersici causing corky root disease was reduced by application of chitin (Biosol) as soil amendment in greenhous-pot experiments. Compared to untreated control plants showing extensive root rot or plants grown in steamed soil, plants treated with chitin showed limited root rot and reached 62% of the average fresh weight of plants grown in steamed soil.
