Download PDF Fungicide chemistry, both new and old, is increasingly coming under pressure, with selection pressure in the field and regulatory hurdles thinning down azole and multi-site options. CPM finds out how plants can be given a bit of help with their own defences. Like most things in nature, optimal metabolic function in plants is all about balance. By Lucy de la Pasture For millennia, signals – a puff of smoke, a wave of a flag or a flare lighting up the sky – have been used to draw attention to the fact there’s danger or trouble ahead. Plants are no different, using chemicals to signal, not just to their own defences but to those around them, that something is amiss. Land-based plants have evolved unique survival strategies, explains Unium director John Haywood, particularly as they are sedentary. “This makes them subject to intense biotic stress – such as herbivory and disease – as well as abiotic stresses such as drought, fire and climatic extremes. “Part of their evolutionary success is due to the plant’s ability to detect potential threats and defend themselves using physical (cell walls), chemical (phytoalexins) and protein/enzymatic defence systems (pathogenesis-related proteins).” When the plant receives a…
