Fenamidone: Human Health Risk Assessment for Proposed Uses on Cotton, Carrot, Sunflower, Brassica Vegetables (group 5), Leafy (except Brassica) Vegetables (group 4), Fruiting Vegetables (group 8) and Strawberry (rotational crop).
Fenamidone is a chiral compound with the technical product consisting of 98.5% S-fenamidone. Fenamidone is a broad-spectrum foliar fungicide belonging to the imidazolinone class of chemicals called quinone outside inhibitors (QOIs). These compounds inhibit the quinone outside site within the electron transport system in susceptible fungi species. Fenamidone is currently registered for application to lettuce (head and leaf), bulb vegetables, cucurbit vegetables, tuberous and corm vegetables, tomato, and grape with tolerances for residues of fenamidone per se ranging from 0.02-20 ppm (40 CFR 180.579(a)(1)).
