Comparison of systemic herbicide and paraquat tank mixtures applied under sunlight or evening conditions on glyphosate resistant sowthistle – pot experiment 2014

Abstract

Key findings • Glyphosate resistant sowthistle was fully controlled by tank mixes of selected systemic herbicides and paraquat at the early flowering growth stage. • There was no difference in control between day and night applications of these tank mixes. • Although glyphosate resistant, the sowthistle was controlled with a treatment containing a mix of glyphosate + paraquat when applied either during day time or during the evening. • A tank mix of paraquat and VelocityR appears to have good potential due to its excellent early brownout of sowthistle, irrespective of day or evening application. The brownout (speed of plant death) was faster than the other treatments examined in this study.
