Se determinaron los efectos del vol., la sincronizacion y el no. de aspersiones de benomil y el arreglo de las boquillas en la eficacia del control quimico de moho blanco (Sclerotinia sclerotiorum) de frijol blanco en cinco ensayos. Se obtuvieron la mayor supresion de la enfermedad y los mayores aumentos de rendimiento de semilla cuando se aplico el fungicida en floracion total, a una dosis de 1.1 kg de i.a. en 550 l de agua/ha, utilizando tres boquillas planas tipo ventilador/hilera, una boquilla en un aguilon horizontal por encima de la hilera para dirigir la aspersion hacia abajo y una boquilla a cada lado de la hilera, sostenida por un aguilon sobre largueros a 8 cm del suelo para dirigir la aspersion hacia la base de las plantas. El control de la enfermedad fue menos efectivo cuando se redujo el vol. de aspersion de 550 a 243 l/ha y cuando se organizaron las boquillas en un aguilon horizontal y en brazos movibles o solo en un aguilon horizontal. El nivel de control de la enfermedad no dependio del tiempo de aspersion durante la floracion pero se relaciono directamente con el no. de flores en la cubierta vegetal que recibieron fungicida.

The effects of volume, timing and number of sprays of benomyl, and arrangement of nozzles on the efficacy of chemical control of white mold (Sclerotinia sclerotiorum) of white bean (Phaseolus vulgaris) were determined in five trials. The greatest suppression of disease and the greatest increases in seed yield were obtained when fungicide was applied at full bloom at a dose of 1.1 kg a.i./ha in 550 L water/ha through three flat-fan nozzles per row, one nozzle on a horizontal boom above the row to direct spray downward and one on each side of the row and held by skid booms 8 cm above the soil surface to direct spray at the base of the plants. Disease control was less effective when the volume of spray was reduced from 550 L/ha to 243 L/ha and when nozzles were arranged on a horizontal boom and drop arms or on a horizontal boom only. The level of disease control did not depend on the time of spraying during flowering but was directly related to the number of blossoms within the canopy that received fungicide. (AS) eng
