Growth ratio was calculated as the fraction of the value of colony diameter grown in the presence and in the absence of Induratia isolate and expressed as percentage
Tests were repeated three times and means ± standard deviation were calculated
Viability of each Aspergillus species was evaluated after 6 days in fresh PDA dishes (free of Induratia VOCs)
