Baseline sensitivity to the SDHI fungicide pydiflumetofen and resistance mechanisms in Fusarium oxysporum, one of the causal agents of soybean root rot in China.
BACKGROUND Soybean root rot (SRR) is a devastating disease that severely reduces yield and quality in China, with Fusarium oxysporum recognized as one of the most prevalent causal agents. Pydiflumetofen, a new-generation succinate dehydrogenase inhibitor (SDHI) fungicide, exhibits potent efficacy against Fusarium spp....
