Evaluating the Impact of Spray Volume on Effectiveness of the Sooty Blotch/flyspeck Warning System at Three Commercial Orchards in Central Iowa

Authors: , ,

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 the second cover, sprays are made at 2-week intervals until harvest.
