Knockdown Control of Common Sowthistle in Fallow locations
Aims

To evaluate mixtures of paraquat with Group 14 herbicides for the knockdown control of common sowthistle in fallow

Key messages

Common sowthistle is one of the most common, problem weeds in the northern cropping region. It is particularly difficult to manage in fallow due to increasing levels of glyphosate tolerance together with a capability to emerge in all seasons. In recent years, a number of new Group 14 (G) herbicides have been registered for improved speed of weed burndown or brownout and control when mixed with glyphosate or paraquat. This project was designed to evaluate the impact of mixtures of Group 14 (G) herbicides with paraquat (Gramoxone 250 formulation) when used as a 2nd knock application. The 1st knock was an application of Glyphosate 450 at 500 mL/ha. This rate was chosen to provide sub lethal control of common sowthistle and allow a more effective evaluation of the impact of the Group G mixtures with paraquat. Standalone applications of Terrador and Sharpen were also applied.
