Mesotrione control and pigment concentration of large crabgrass (<i>Digitaria sanguinalis</i>) under varying environmental conditions

Abstract

Although mesotrione efficacy has previously been reported to vary according to environmental factors, mesotrione control of large crabgrass did not vary with measured temperature and irradiance levels in this study. On account of crabgrass convalescence, secondary applications of mesotrione may control large crabgrass more effectively when applied prior to 21 DAT.
