b'On the Teagasc Tillage Edge podcast this week, Michael Hennessy was joined by Liz Glynn of Corteva, who chatted about broad leaf weed control and herbicide resistance issues in Ireland. \\n\\nLiz told the Tillage Edge there are problems with broad leaved weeds escaping uncontrolled or partially controlled through to harvest. Liz said farmers need to check a number of areas such as weed type, weed size, growing conditions and herbicide type/rate to ensure that all conditions are correct to control the weed. Where there are correct and poor weed control is observed then herbicide resistance can be considered. \\n \\nLiz mentioned resistance weeds such as chickweed were increasingly showing up on farm in the past couple of years. Corteva trials were showing increased resistance in chickweed to SU herbicides but herbicides like fluroxypyr (Starane) control these resistance weeds. \\n \\nLiz maintains where there is good practice including rotations, alternating crops, ensuring competitive canopies and good selection of correct herbicides, then growers will be able to reduce the likelihood of resistance on their farms. \\n \\nFor more episodes and information from the Tillage Edge podcast go to\\nhttps://www.teagasc.ie/crops/crops/the-tillage-edge-podcast/\\n \\nThe Tillage Edge is a co-production with LastCastMedia'
