Abstract

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) injured actively growing bermudagrass [Cynodon dactylon (L.) Pers. # CYNDA] immediately after treatment. Treatments made at the normal (1.1 + 0.6 + 0.1 kg ai/ha) rate in August, September, or October, did not affect winter survival. A triple rate (3.3 + 1.8 + 0.3 kg/ha) delayed growth of ‘Tifgreen’ and ‘Tifdwarf’ more the following April than ‘Tifway’ and ‘Ormond’. Due to a reduction in turf stand from herbicide treatments, the cover of common chickweed [Stellaria media (L.) Cyrillo # STEME] was higher in plots to which herbicides were applied in August or September than in untreated plots. The cover of weeds was lower in Tifway and Ormond plots than in Tifgreen and Tifdwarf plots.
