I am a new member here and this is my first post. I live on the east coast of Central Florida, in zone 9b.
I purchased a blackberry plant a few months ago and planted it in full sun in the backyard. I am training it on a trellis and I has been doing very well. Over the last month or so, I have been noticing some curled, folded over leaves. When opened there is a small white worm or a wriggly light brown cocoon. I believe it is some type of leaf roller. I have treated the plant twice with Organocide but the pests persist.
I really appreciate any information about the pest and how to treat.
Thanks so much.
