Abstract

Absorption, translocation, metabolism, and action of 7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylic acid (endothall) in annual bluegrass (Poa annua L.), Kentucky bluegrass (Poa pratensis L. ‘Merion’), and creeping bentgrass (Agrostis stolonifera L. ‘Penncross’) were studied. Selective action on annual bluegrass from root applications of endothall was attributed to differences in absorption and action of the herbicide. Morphological differences among species, spray retention, and endothall action contributed to selectivity following foliar applications.
