Qualidade sanitária de sementes de aveia preta cv. brs 139 (Avena strigosa SCHREB) submetidas ao envelhecimento acelerado Sanitary Quality of Black Oat Seeds cv. Brs 139 (Avena strigosa SCHREB) submitted to accelerated aging

The work aimed to study the effects of different treatments on seed health black oat cv. BRS 139. The seeds were subjected to the following treatments: Vincit® 50SC, Vincit® Trichodel® + 50SC, Trichodel® and Witness without treatment. Then, were packed in boxes of seed dis- persal, substrate type filter paper dampened with distilled water and sterile and remained in chambers at temperature of B.O.D 25oC, with photoperiod of 12 hours, until the assessment. Fungi associated with the seeds were identified with the aid of stereoscopic microscopes and optical, after seven days of incubation. The statistical design was a completely randomized with four treatments and eight reps of 50 seeds each. The fungi Aspergillus spp., Fusarium spp., Penicillium spp., Rhizoctonia spp., Rhizopus spp. and Trichoderma spp. were identified in seeds. The results showed that the chemical (Vincit ® 50SC), isolated or associated with Trichodel ® , was effective for the control of potentially pathogenic fungi to Oat seeds black. it is concluded that the most efficient treatments for the control of fungi present consist in chemical Vincit ® 50SC used alone and when associated with the biological product Trichodel ® .
