Background Information for this page
Return to radar list for Middletown RI
     2nd generation flyspeck spores from border row hosts become available around June 24.  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 24, the estimated end of the 50 wet hour postinfection control window is June 30.
