I'm not entirely convinced with the whole PGR-on-thin-crop=improved tillering argument. I only apply Moddus or anything non CCC to a crop that is at risk of lodging. CCC at £1.70/ha is cheap insurance.
If it's thin the best thing is a set of rolls it'll do far more good than something out of a can.[/QUOTE]
I have rolled some late drilled WW, I know some do it several times, what is the latest GS its safe to roll?
