| 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 latest
possible harvest date. Postinfection control of flyspeck requires application of a strobilurin or Topsin M fungicide within 50 wet hours aft June 22, the estimated end of the 50 wet hour postinfection control window is June 24. Flyspeck infection risk increases with development of 3rd generation spores around July 3. Flyspeck infections that occur after protective fungicide coverage is depleted but within about 30 days before harvest will only have enough development time to appear if unusually wet weather prevails in the weeks prior to harvest. Presumably, late-season flyspeck infections require about 265 flyspeck growth hours to become visible. |
