Abstract: The traditional methods to protect crops from diseases and thus improving growth and yield are based on the use of chemicals. Trichoderma spp. provide protection against plant pathogens such as Pythium, Rbizoctonia, Fusarium, Thielaviopsis and Botrytis. In the present work we have investigated the ability of T. harzianum T22 and T. atroviride P1 to improve plant growth of locally important horticultural crops (lettuce, tomatoes and peppers) and to prevent disease in the greenhouse and field. Plant growth stimulation by T. harzianum T22 and T. atroviride P1 was demonstrated by determining the weight of fresh and dry roots and above ground biomass, the height of plants, the number of leaves (lettuce, tomatoes and peppers) and fruits (tomatoes. and peppers). No disease symptoms were found during production, although Fusarium sp. strains pathogenic to tomato were detected in the soil. Compounds containing copper oxychloride are frequently used for fungal disease control in agriculture. In order to investigate the compatibility of T. harzianum T22 and T. atroviride P1 with copper oxychloride applications, the effect on mycelia growth was monitored in both liquid and solid medium. In general, the tests indicated a high level of tolerance of the Trichoderma strains to concentrations of copper oxychloride varying from 0.1 to 5 mM.
