IPM Message for Cranberry Growers: August 7, 2020

August 7, 2020

Flea beetle is out (couple spots with high numbers and damage) and more root stress/heat issues have been reported. Fairy ring and Phytophthora symptoms are evident in affected areas (normal to see them this time of the year, especially with the high temperatures we have been experiencing) (thanks to Erika Saalau Rojas, OSC).

Do you have dodder? As part of a project to better understand the biology of dodder, we would like to collect infected cranberry and weed stems post-harvest and throughout the winter. Please call Hilary x21 or Katie x43 if you have an infestation on your farm that we could use. We would like to mark the areas NOW and then come back in the fall and winter to collect samples.

We have rescheduled our April Pesticide Safety Meeting to online via Zoom for 2 nights in August (18th and 20th, 6-8 pm). Agenda will be different for each night. We already have 30 growers signed up from April. If you want to attend, need 4 contact hours (2 credits for each night), or just want to get the latest updates, please go to our newsletter to register.  There is also a new pest alert on the golden casebearer.  For the August issue of the newsletter and the Pest Alert sheet click here:  Note that you should plan to sign on by 5:45 pm.  If you need help with zoom, contact Robyn or Marty: or

An Aquatic Plant Survey is being sent out to all of you to assess the presence and impact of aquatic weeds on your farm. This information will allow us to better address your management and control needs for aquatic weeds. You will receive the survey in the same way (email or snail mail) you receive our newsletter.  It should only take a few minutes to fill out, so thank you ahead of time for your help.

Just as a reminder that the Station is still currently closed to the public to reduce person-to person exposure. We are working remotely and will likely be doing so for the foreseeable future. You can reach any of us by phone by calling the Station (508-295-2212) for the phone extension directory or by email, you can find our individual contact information at:
