Glyphosate (Roundup) Injury on Red Raspberry

Asked May 26, 2017, 8:01 AM EDT

My Red raspberries leaves are turning light pale green. Some leaves are malformed. Help! What's going on with my patch???? The first and second images are what we first noticed last week. It was scattered throughout the patch. The last image is what we noticed this morning - this is prevalent throughout the patch. Note, the black raspberries still look OK.

Looks to me that they were exposed to glyphosate (Roundup) last year. The symptoms of glyphosate may not be obvious at first especially late in the year, but the symptoms are pretty similar in most plant tiny yellow leaves and shoots the following year and often tufts of small shoots. I have attached some pictures I have of glyphosate injury in raspberries and blackberries.
Here are some links to articles I have written.
You should cut out the affected shoots but the plants should survive.
