Galera®, based on clopyralid and picloram, is the main spring-applied herbicide for winter oilseed rape as it controls cleavers, mayweeds, sow-thistles and thistles, all weeds that compete with and interfere with the crop. It can be applied from the 4 leaf stage of the crop up to the point just before flower buds are visible above the crop canopy. Usually it’s cut off is at the end of March or beginning of April.
In practical terms, the trigger point for Galera® applications tends to be when crops and weeds start to grow, usually after fertiliser applications.
