Abstract
 
Culture filtrates of Trichoderma spp. inhibited the linear growth of both Sclerotium cepivorum and Fusarium oxysporum f. sp. cepae. Also, the culture filtrates of T.harzianum altered the mycelia! permeabili­ty of S. cepivorum more than F. oxysporum f. sp. cepae. Amount of total free amino acids increased in onion plants infect­ed with S. cepivorum or F. oxysporum f. sp cepae and also when plants were treated with Trichoderma spp, in the presence of one of the two pathogens. The same trend was observed with respect to amount of free phenols, while the same treatments reduced the amount of total carbohydrates and total phenols.
