Abstract
Foliar-applied herbicides were evaluated in one greenhouse and five field studies for control of silver beardgrass (Andropogon saccharoidesSwartz. # ANOSA). In the greenhouse, terbutryn [N-(1,1-dimethylethyl)-N′-ethyl-6-(methylthio)-1,3,5-triazine-2,4-diamine] and the isopropylamine salt of glyphosate [N-(phosphonomethyl) glycine] at 3.4 kg ai/ha each consistently controlled silver beardgrass from 7 to 75 days after treatment. Field studies were conducted to investigate silver beardgrass control as influenced by herbicides and timing of herbicide application. Generally, glyphosate at 1.1 and 1.7 kg/ha satisfactorily controlled silver beardgrass with little or no permanent damage to the existing bermudagrass [Cynodon dactylon(L.) Pers. # CYNDA] turf. Decreasing water carrier volume from 374 to 187 L/ha did not affect phytoactivity of terbutryn at 3.4 kg/ha or glyphosate at 0.4, 0.6, 0.8, or 1.1 kg/ha.
