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.
