| dc.description | Three isolates of the fungal pathogen Colletotrichum dematium var. truncata were obtained from soybean (Glycine max) during the 1975 growing season in central and southern Illinois and labeled Cd-1, Cd-2 and Cd-3. The three isolates produced curved conidia measuring between 17.8 to 23.3 µ long and 3.2 to 5.1 µ wide. Growth rate and spore production were variable among the three isolates with Cd-3 producing the most spores per cm2 of colony growth and Cd-2 producing the largest colony growth at 25° C. Isolate Cd-1, found to be tolerant to benomyl in vitro, showed a uniform radial-growth pattern on potato-dextrose agar amended with 1 to 350 µg/ml commercial benomyl, while isolates Cd-2 and Cd-3 showed a bimodal-type growth curve. Colletotrichum glycine and Coltetotrichum musae were sensitive to benomyl. | en-US |
| dc.description | En 1975 tres subcultivos de Colletotrichum dematium var. truncata se obtuvieron de sojas sembradas en las regiones central y meridional de Illinois. Estas se designaron Cd-1, Cd-2 y Cd-3. Los tres subcultivos produjeron conidios curvados que medían entre 17.8 y 23.3 µ de largo y de 3.2 a 5.1 de ancho. La tasa de crecimiento y la producción de esporas de los tres variaron: el Cd-3 fue el que más esporas produjo por cm2 y el Cd-2 el que produjo la colonia más grande a 25° C. El Cd-1 fue tolerante al benomyl in vitro y presentó un crecimiento radial uniforme en agar de papa y dextrosa modificado con 1 a 350 µg/ml de benomyl comercial. Los subcultivos Cd-2 y Cd-3 presentaron una curva bimodal de crecimiento. Colletotrichum glycine y C. musae fueron sensibles al benomyl. | es-ES |
