Flyspeck prevention, Full-dose Pristine: August-September spray dates

a
Return to radar list for Hancock NH
Weather data for Hancock NH.  Forecast values begin September 15, 2011
    Continuous protection from June 25 until 30 days before harvest is recommended.  Flyspeck infections that begin before August 22 are likely to become visible around September 20.  Infections that begin before September 5 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.
     Application a strobilurin or Topsin M fungicide within 50 wet hours after the 'Protection end date' of the previous fungicide application may provide postinfection control.
