Description
Summary:The use of bioprotectors in the coating of seeds is increasing, and these become an alternative for the use of chemical fungicides. The aim of this work was to evaluate the use of Trichoderma spp., with or without polymerization, in the control of pathogens associated with black oats (Avena strigosa) and barley (Hordeum vulgare) seeds of the cultivars 'Comum' (black oats) and BRS Cauê (barley), 2014 crop. After asepsis and dried of the seeds, the treatments were applied, using a dose of 5 mL of Trichoderma spp. kg-1 and 10 mL of seed polymer kg-1 of seeds. Sanity tests; germination; germination and emergency rate index; length of seedling (shoot and root); and fresh and dry weight were performed. The coating of oat and barley seeds with Trichoderma spp. was efficient in the control of pathogens, as well as increased the germination and development of the seedlings for both cultures evaluated.
