From science to market—the fungicide discovery and approval pipeline. Historically, the biological activity profile (fungicidal potency and spectrum) was used to filter hit compounds to lead molecules. Nowadays, regulatory requirements regarding human and ecotoxicological safety mean that proxy assays for these regulatory requirements are now utilised as early in the discovery pipeline as possible as part of the selection criteria for compound progression. It will typically take 10–12 years for a new fungicide to pass through the various stages of research (lead generation, early and late lead evaluation, optimisation and candidate confirmation) before promotion into evaluation and, finally, product development. After reaching the market, a significant amount of investment is still required for product lifecycle management (e.g. product monitoring feeds into improvements in formulation)
