Fleabane away on a germinating rainfall event in late April. Already has its roots down to the moisture. Will just sit there all winter and grow roots, with minimal above ground growth. Won't 'bolt' until days lengthen in spring. This is the stage where herbicides are effective.

Often hear industry saying certain pre-ems "don't leach & stay in the top few cm of soil" Data below from a 2024 field trial 4 common pre-ems (deliberately left nameless) 2 soils 0-15cm gray & 15-30cm white at days after application Similar trends with all products & sites

SCU research team about to kick off a massive task to establish dose responses for a wide range of crops to an even wider range of pre-em herbicides, across several soil types. Pic below is Reflex to wheat - just as a practice to get the trial technique sorted.
