Interactions between prosulfocarb and trifluralin metabolism in annual ryegrass (Lolium rigidum)
Metabolism of prosulfocarb and trifluralin was investigated in L. rigidum populations with different levels of resistance to prosulfocarb, trifluralin and also pyroxasulfone, which is detoxified by glutathione (GSH) conjugation.
Rainfall affects leaching of pre-emergent herbicide from wheat residue into the soil
No-tillage with stubble retention is a widely used cropping system for its conservation and yield benefits. The no-tillage farming system in southern Australia relies heavily on herbicides for weed management, but heavy crop residues may have a negative impact on the activity of pre-emergent herbicides applied.
Effect of crop residues on interception and activity of prosulfocarb, pyroxasulfone, and trifluralin
Crop residue retention on the soil surface in the no-tillage system can intercept pre-emergent herbicides and reduce their efficacy. Three experiments were conducted to investigate the effect of crop residue amount (0, 1, 2 and 4 t ha–1), moisture (wet versus dry), type (wheat, barley, canola, chickpea and lupin) and age (fresh or aged for one year) on the interception and subsequent leaching of prosulfocarb, pyroxasulfone, and trifluralin from the residue into soil.
Cross-resistance to prosulfocarb and triallate in pyroxasulfone-resistant Lolium rigidum
Plants can rapidly evolve resistance to herbicide in response to repeated selection. This study focuses on cross-resistance patterns observed in Lolium rigidum following pyroxasulfone recurrent selection.
Understanding the potential for resistance evolution to the new herbicide pyroxasulfone: field selection at high doses versus recurrent selection at low doses
Pyroxasulfone is a new pre-emergence herbicide that provides effective control of Lolium rigidum, including populations with evolved resistance to multiple herbicide modes of action.
