Pre-harvest glyphosate decisions

The conversations around pre-harvest glyphosate are already occurring. As always, it will be vitally important for pre-harvest timing decisions to be based on grain moisture levels. The target pre-harvest glyphosate timing for wheat is barley when the least advanced part of the crop is at 30 per cent grain moisture. Producers and agronomists must also be mindful of late tillers and regrowth as these parts of the crop may impact grain moisture assessment. Be sure to check out the guides from Keep It Clean to ensure staging is done correctly.
