En la Estación Experimental Fabio Baudrit M., situada en el Barrio San José, de la Provincia de Alajuela, entre febrero de 1987 y febrero de 1989 se realizó una investigación con el objetivo de evaluar la influencia de la época de aplicación de dos fuentes de nitrógeno, sobre la tolerancia del arroz (Oryza sativa L.) y de la caminadora (Rottboellia cochinchinensis) a los herbicidas haloxyfop-metil y fenoxaprop-etil. El fenoxaprop-etil a 100 g i.a./ha fue el tratamiento más selectivo, en tanto el haloxifop-metil causó mayores daños. La dosis de 200 g i.a./ha para ambos herbicidas fue la más perjudicial. La fertilización con nitrógeno disminuyó los síntomas de toxicidad, especialmente cuando se aplicó el Sulfato de Amonio cinco días antes que...
