Fig 5: Weekly mean black rot count per tree, from a total of ten trees, over 13 week for 3 orchards. Black rot was indicated by frog eyed leaf spot. Five leaves and 10 spurs/terminals were sampled from 10 trees in each condition. While Black Rot is statistically higher in Orchard 1's treatment (CAS) condition, counts are too low to raise concern. Bars indicate standard error.
