Growth of aggressive isolates of Trichoderma aggressivum f. Europaeum in dependence on temperature and medium

The effect of temperature and medium on the aggressive Trichoderma aggressivum f. europaeum isolates mycelium growth was investigated. Two isolates of the species from mushroom-growing houses in Western Europe and 20 isolates from Polish mushroom-growing houses and oyster mushroom cultivations were taken into consideration. Growth of experimental isolates was examined on standard agar medium and on manure medium at 15, 20, 25, 30 and 35°C. The mycelium of the examined isolates grew better on the manure medium than on standard agar medium and the optimum temperature for all the examined isolates was 25 and 30°C.
