Four fungicides for the control of pathogenic fungi which infect the seed of rice, were tested. Three groups of seed with low, half and high germination were treated with Arasan (381 g), Dithane M-45 (381 g), Vitavax-300 (150 g) and Sisthane (176 cc) for ecah of the 100 g seed. For the measurements of these products, tests of pathology and germination were conducted, simultaneously at 0, 30, 60, 90 and 120 days after the treatments had been made. With the sistemic fungicides Vitavax-300 and Sisthane there were obtained the higher percentages of germination, increasing it to 26 and 38%, respectively for the group with half germination. The increase in the group with low germination was increased in an 11 and 18% by using the fungicides Dithane M-45 and Arasan, in the group with half germination. In the low one, the increase was of 36 and 18%. On the other hand, the lowest percentages of incidence of pathogenic fungi in seeds were obtained when treated with Arasan and Dithane M-45. None of the fungicides afected the germination 120 days after the treatment.

Tres lotes de semilla con baja, mediana y alta germinación fueron tratados con Arasan (381 g), Dithane M-45 (381 g), Vitavax-300 (150 g) y Sisthane (176 cc) por cada 100 g de semilla. Para la evaluación de estos productos se llevaron a cabo simultáneamente pruebas de patología y germinación a 0, 30, 60, 90 y 120 días de efectuados los tratamientos. Con los fungicidas sistémicos, Vitavax-300 y Sisthane se obtuvieron los mayores porcentajes de germinación, aumentando en un 26 y 38%, respectivamente la germinación del lote de mediana germinación. El aumento en el lote de baja germinación fue de 25 y 38% en el mismo orden, sin que la germinación total sobrepasara el 80 por ciento. Los fungicidas protectores Dithane M-45 y Arasan, aumentaron en el lote de mediana germinación en un 11 y 18%, respectivamente. En el lote de baja germinación, el aumento fue de 36 y 18%. Por otro lado, de las semillas tratadas con Arasan y Dithane M-45 se obtuvieron los porcentajes más bajos de incidencia de hongos patógenos. Ningún fungicida afectó la germinación hasta 120 días después del tratamiento.

For the measurements of these products, tests of pathology and germination were conducted, simultaneously at 0, 30, 60, 90 and 120 days after the treatments had been made. With the sistemic fungicides Vitavax-300 and Sisthane there were obtained the higher percentages of germination, increasing it to 26 and 38%, respectively for the group with half germination. The increase in the group with low germination was increased in an 11 and 18% by using the fungicides Dithane M-45 and Arasan, in the group with half germination. In the low one, the increase was of 36 and 18%. On the other hand, the lowest percentages of incidence of pathogenic fungi in seeds were obtained when treated with Arasan and Dithane M-45. None of the fungicides afected the germination 120 days after the treatment. |
