Continuous protection from June 10 until 30 days before harvest is
recommended. Risk of new flyspeck
infections increases around July 14, and increases again around August 22.
Flyspeck infections that begin before August 17 are likely to become visible around September 20. Infections that begin before September 3 are likely to become visible around October 20. But warm wet weather in September can accelerate flyspeck development resulting in earlier dates of flyspeck appearance before harvest. Postinfection control of flyspeck may occur with application a strobilurin or Topsin M fungicide within 50 wet hours after the 'Protection end date' of the previous fungicide application. |

Date flyspeck infections that started after end of protection
could appear (Left side = rough estimate of flyspeck show date for dense canopy trees if weather beyond forecast range is in top 20% of years for both temperature and wet hours. x = show date is within forecast range. Right side = rough estimate of flyspeck show date for small, open canopy, low-risk trees.) |
