Maintaining the Efficacy of Foliar Fungicides for Tobacco Disease Management (PPFS-AG-T-05)
Fungicides are organized into groups based on their mode of action, which is the mechanism a pesticide or chemical affects its target pest. Management of resistance to fungicides is based on alternating the use of particular modes of action, or FRAC groups. Alternating FRAC groups reduces the chance of developing widespread resistance, thus, prolonging the efficacy of these chemicals.
This new publication discusses how resistance to fungicides develops and fungicide resistance management. Also included is a practical example of designing a tobacco fungicide program in which multiple FRAC groups are used to manage blue mold.
Maintaining the Efficacy of Foliar Fungicides for Tobacco Disease Management (PPFS-AG-T-05) is available online.
