Abstract

The control of winter annuals in dormant bermudagrass [Cynodon dactylon (L.) Pers. ‘Common’] has not been consistent with available herbicides. Experiments were conducted to evaluate rates and number of glyphosate [N-(phosphonomethyl)glycine] applications for control of winter annuals growing in dormant bermudagrass. Glyphosate applied as a single treatment at 0.6 kg/ha consistently controlled more parsley-piert (Alchemilla microcorpa Boissier Reuter), corn speedwell (Veronica arvensis L.), and henbit (Lamium amplexicaule L.) than paraquat (1,1′-dimethyl-4,4′-bipyridinium ion) or combination treatments of 2,4-D [(2,4-dichlorophenoxy)acetic acid) + mecoprop 2[(4-chloro-o-tolyl)oxy] propionic acid + dicamba (3,6-dichloro-o-anisic acid). There was no difference between glyphosate and paraquat control of annual bluegrass (Poa annua L.) and common chickweed [Stellaria media (L.) Cyrillo]. Glyphosate treatments did not injure the bermudagrass the following spring.
