Abstract

Field studies were conducted from 1986 through 1989 to evaluate the tolerance of three clover species to selected POST herbicides. 2,4-D at 0.8 and 1.7 kg ha−1 injured rose and berseem clovers while the high rate injured subterranean clover. Bentazon and pronamide did not injure rose or subterranean clover; however, pronamide at 3.4 kg ha−1 injured berseem clover 18% when rated 72 days after treatment.
