Description

Varieties of Guaymí bean and the MUS 181 line were evaluated in five locations in Costa Rica, in five plant populations (140.000; 170.000; 200.000; 230.000 and 260.000 plants per hectare). Some plants were sprayed with benomyl 50PM fungicide at 0.35 kg per hectare, while others did not receive such treatment. Yield losses caused by pathogenic agents were determined, and an economic analysis of the treatment was performed. A low incidence of Mustia Hilachosa/bean diseases was reported on treated plants. Plant populations of 140.000 and 170.000 plants per hectare produced the greatest profit and the highest marginal return rateo
En cinco localidades de Costa Rica se evaluaron las variedades de frijol Guaymí y la línea MUS 181 en cinco densidades de siembra (140.000, 170.000, 200.000, 230.000 y 260.000 plantas por hectárea), con y sin aplicación de fungicida Benomy1 50 PM en dosis de 0,35 kg/ha. Se determinaron las pérdidas en rendimiento causadas por patógenos y se realizó un análisis económico de la actividad. Hubo baja incidencia de Mustia Hilachosa y las densidades de siembra de 140.000 a 170.000 plantas por hectárea presentaron los mayores beneficios netos y la más alta tasa de retorno marginal.
