Recognizing Glyphosate Injury on Small Fruit Crops

I get several calls this time year about herbicide injury, especially glyphosate injury, to small fruit crops.  Below are some images of symptoms of glyphosate injury on raspberry, blueberry and blackberry.  When spraying glyphosate around fruit crops (or any non-target crop) remember to use best practices to prevent drift.  Best practices include spraying when wind is below 10 mph (3-7 mph is preferable), using a shield on hand-held sprayers, and adjusting the nozzle on your sprayer to a coarser droplet size.  Small fruit crops can generally withstand some damage but if injury is severe or the flowers are injured, yield will be reduced.  Plant vigour the following year may also be reduced.
