Abstract

The present work aimed to evaluate plant injury caused by residues in the soil of the formulated mixture of imazethapyr and imazapic to a nontolerant genotype of rice (IRGA 417) drilled at 371 and 705 d after herbicide application (DAA). Herbicide carryover reduced up to 55% of the grain yield of the IRGA 417 drilled at 371 DAA, and plant injury was still evident at 705 DAA but without grain yield reduction.

El objetivo del presente trabajo fue evaluar los daños causados por residuos en el suelo, de una mezcla de imazethapyr e imazapic a plantas de un genotipo de arroz (IRGA 417) no tolerante, tomada la muestra entre los 371 y los 705 días después de la aplicación del herbicida (DAA). El efecto residual del herbicida redujo en hasta 55% el rendimiento del grano de las plantas de IRGA 417 muestreadas a los 371 DAA. Los daños a la planta fueron aún evidentes a los 705 DAA pero sin reducción en el rendimiento del grano.
