Week of July 21 – 25 Scouting Report Summary


  • Apples: Fruit is developing.  Some codling moth larvae were found in some fruit this week.  Aphids and red mites remained at low levels.  There was a small increase in codling moths caught in pheromone traps.  Apple maggot trap numbers remain at 0.
  • Grapes:  Scouts noted symptoms of grape black rot in some locations.  Light to moderate defoliation due to Japanese beetle feeding has been found across vineyards.  The recommendation to control Japanese beetles was made in one location.  The second generation flight of grape berry moth has started, moths were being caught in traps and this will trigger a timed control treatment to prevent damage to grape fruit.
  • Brambles, Blackberries and Raspberries: Spotted Wing Drosophila (SWD) were again caught in traps this week from traps set in raspberries and blueberries.  Growers are advised to start a preventative spray program for ripening berries.
  • Blueberries:  Harvest continues for mid-season blueberries.  SWD have been found in blueberry traps.  Growers with ripening fruit should consider a preventative spray program.  Blueberry maggot traps have remained at 0.
