A fungus that grows on pinecones yields a compound with antifungal activity that has become the natural model for a significant innovation in crop protection. Variation and optimization of the lead structure of strobilurin A (1) and selection of derivatives which fulfill all practical requirements, for example, kresoxim-methyl (2), led to an exciting and pan-industrial competition for the development of the strobilurines as a new, highly active, and broadly applicable class of fungicides-a fascinating success story.
Keywords: Active substance research; Fungicides; Natural products; Strobilurins; Structure-activity relationships.
