Abstract

Glyphosate at 0.5 kg ha−1+surfactant (0.1%) and glyphosate at 1.0 kg ha−1 provided most effective control of Erigeron canadensis but was toxic to the grasses in natural grasslands. Significantly higher herbage yield was recorded by 2, 4-D Na at 0.75 kg ha−1 + surfactant (0.1%) and 2, 4-D (EE) 1.25 kg ha-1.
