2nd generation flyspeck spores from border row hosts become available
around June 22. Beyond that date
preventive or postinfection flyspeck control is advised up until 30 days
before the end of harvest. Postinfection control of flyspeck requires application of a strobilurin or Topsin M fungicide within 50 wet hours after the 'Protection end date' of the previous fungicide application. For flyspeck infections starting on unprotected apples on June 22, the estimated end of the 50 wet hour postinfection control window is June 25. Flyspeck infection risk increases with development of 3rd generation spores around July 14, and peaks with 4th generation starting around August 4. If the 'Protection End Date' is within 30 days of final harvest, then flyspeck infections that start after protection wears off will only have enough development time to become visible on fruit if unusually wet weather allows an additional 270+ cumulative wet hours before harvest. |
