Decades of research reveal how fungi evolve to survive chemical treatments

Nature · Published 3 October 2026 Swipe more like this →

In short: A review of fifty years of research shows how plant pathogens develop defenses against common fungicides. By examining various classes of chemicals used in agriculture, researchers have mapped out the molecular mechanisms that allow fungi and oomycetes to persist despite repeated treatments.

Understanding these biological workarounds is essential for protecting global crop yields from disease. The review covers several major fungicide classes and highlights how advancements in molecular biology have enabled faster detection of resistant strains through high-throughput monitoring techniques like PCR.

The study summarizes existing knowledge rather than conducting new experiments, which means it reflects the current state of the field rather than providing new experimental data. It also notes that while management strategies exist, future research into RNA-based and epigenetic fungicides is needed to stay ahead of evolving pathogens.

Why it matters: Understanding how pathogens evolve resistance is key to developing more effective and sustainable ways to protect our food supply.
