Happy Spring, and the 29th March Message

As promised, the apple season has begun today, April 1 with….cold and snow. No, we are not at green tip yet, but I have seen tiny bits of green tissue poking out from some early cultivars and received a report from an orchard in the southern part of the state the other day that they were just around the corner.

I won’t belabor the things that growers need to think about, as a more timely message will be sent once buds start to break. But this is a reminder to start checking your trees regularly and to record bud stages- these are needed for many models in the NEWA system. You also should be tuning up your sprayers, as any day now we’ll be making the call to apply copper to reduce overwintering fire blight and prevent early season apple scab infections.

I would like to take this moment to share the UMASS March Message, which is both linked and attached. This summary coordinated by Dr. Jaime Pinero and the UMASS Fruit Team carries on the tradition of the late Ron Prokopy, who summarized the latest IPM research topics for growers just as the season was beginning.

Finally, anyone who missed the New England Winter Fruit Webinars, which included discussion on sprayer calibration, apple insect pest management, and updates to the NEWA system, can view them here: https://www.youtube.com/playlist?list=PLUL3FZJYGp3n04GfGTlQgoXoKBk7R2Xx7
