Walking through a maturing cereal field in late spring / early summer is an excellent time to assess how successful (or not) your weed management strategy has been in that season. This may be the correct time for assessing some of the most troublesome weed species that UK farmers have to control like black-grass and cleavers. But what about those weed species that never make it out above the crop canopy, that prefer to hug the ground, stay out of site and complete their life cycle way before the crop matures?
