Abstract

The Brown/Sutton/Hartman sooty blotch flyspeck (SBFS) warning system, developed in North Carolina and modified in Kentucky, extends the period between first-cover and second-cover fungicide sprays until a total of 175 hours of wetness has been measured in the orchard canopy. After second cover, sprays are made at two-week intervals until harvest.
