IPM Message for Cranberry Growers: Jun 19, 2017

June 19, 2017

 Most cranberry varieties (except Howes) are approaching 20% bloom at State Bog.  This is the time to start thinking about your first fungicide application and to plan the rest of your fungicide program. Call Erika at ext 18 if you have any questions.

Bloom is coming along slowly so far this year but with the warm temperatures predicted for this week, things could move along quite quickly.  The Rutgers varieties are usually ahead of all others in terms of bloom and some growers with these varieties have put out their first fungicide already.

Now is the time to put out sprays to control scale, if you have an infestation.  Bees should be in for most bogs by now.  Marty did see a cranberry fruitworm moth out on State Bog today.  It is too late to spray for weevil at this point.  We found 2 Spag moths in our traps at State Bog already.

Attached are photos showing a small cranberry weevil grub that was inside the flower pod and the variable bloom on State Bog (many blooms in foreground, very few in background).
