One thought on “Important SWD Update!

  1. Regarding control:
    Are there any blueberry varieties that are thick-skinned enough to deter egg laying inside the fruit?

    How early after pollination does egg laying occur? Would it work to use a short-season raspberry and then after pollination cover the ends of the canes, or the whole row with a physical barrier like nylon stockings, row cover, or other
    material?
