Wild radish resistant to Atrazine, super-sensitive to Bromoxynil

By Peter Newman Alexander Graham Bell famously said, “When one door closes another door opens, but we so often look so long and so regretfully upon the closed door, that we do not see the ones which open for us.” Atrazine resistant wild radish looks a lot like a door closing, but in many cases, it’s also a door opening for Bromoxynil. Some new research by AHRI PhD student, Huan Lu, has shed some light on Atrazine resistant wild radish and the results have some very practical applications for growers and agronomists. The most common target site mutation that causes…

Wild radish (Raphanus raphanistrum) is a globally important weed of crops. Two atrazine-resistant wild radish populations (R1 and R2), collected fromtheWesternAustralia grain belt, were investigated for resistance to photosystem II (PSII) herbicides.
