Download PDF Ramularia in barley With mounting resistance to single-site chemistries making the control of ramularia in barley increasingly difficult to achieve, Adama is working with CPM to highlight the importance of including a multi-site fungicide in spring spray programmes – not only to ensure crops are adequately protected, but also to prolong the effective lifetime of at-risk products. Lurking unseen in barley crops, ramularia has developed resistance to most chemistry and shows its spots only late in the season. CPM explores how to keep a lid on infections. Ramularia’s ability to mutate and evolve resistance to fungicide chemistry makes it a problem. By Tom Allen-Stevens Ramularia was only acknowledged as a disease in barley in 1998. But in the relatively short space of time since, it’s passed from being a minor disease to a major one, and there are probably more unanswered questions raised about it than there are solutions. For Dr Neil Havis of SRUC, one of the major challenges ramularia poses is its unprecedented ability to mutate and evolve resistance to major fungicides – a good understanding of the pathogen is therefore vital. With chlorothalonil (CTL) falling out of the picture this spring, Adama’s David Roberts…
