Summary
A brown blotch disease of cultivated mushrooms, caused byPseudomonas Tolaasi Paine, has been studied. To get infection under artificial conditions the bacteria had to be grown on media containing extracts from meat or mushrooms. The mushroom extracts were obtained from pilei and pure culture mycelium, with hot as well as with cold water. Under natural conditions old mycelium in the casing soil and stumps of mushrooms left on the beds after picking may provide for the active substances, which probably are extracted and splashed by the water used in spraying the beds. Trashing the beds will cut down the rate of blotched mushrooms.Pseudomonas Tolaasi proved to be resistant to the bactericides tested.
