Abstract

Foliar sprays of 2,4-D, dicamba, and triclopyr were applied to vegetative annual goldeneye at 0.56, 1.1, and 2.2 kg ai ha-1. Mortality was 47% and 64% after treatment with triclopyr and 2,4-D at 2.2 kg ha-1, respectively. Mortality was less than 30% at lower rates. Mortality was 54%, 93%, and 100% after treatment with dicamba at 0.56, 1.1, and 2.2 kg ha-1, respectively. Foliar cover of tobosagrass increased 119% and 92% on plots treated with dicamba at 1.1 and 2.2 kg ha-1, respectively. Herbicide treatment did not affect nitrate concentration (0.03% to 0.05%) in treated plants.
