Description
Summary:	The rice kernel smut (Tilletia barclayana), which is considered as a secondary disease, lately has been growing in importance due to its high infestation levels and effects in seed yield. This disease is favored by elevated air temperatures and humidity; high nitrogen fertilizer rates a late sowing. In order to control it, the use or resistant varieties, appropriate sowing dates and balanced fertilization of the soil, are recommended practices. Key words: Oryza sativa, kernel smut of rice, Tilletia barclayana. A carie-do-arroz (Tilletia barclayana), doenca considerada secundaria na cultura do arroz irrigado, vem ganhando importancia nos ultimos anos devido aos niveis elevados de infestacao e a reducao do rendimento. A doenca e favorecida por temperatura e umidade do ar elevadas, doses altas de nitrogenio e semeadura tardia. Para o manejo, recomenda-se uso de resistencia varietal, semeadura na epoca recomendada e adubacao equilibrada. Palavras-chave: Oryza sativa, carie-do-arroz, Tilletia barclayana.
