Here are some pictures of potential damage from leaf rollers in new planted filberts.

|Leaf damage and new growth damaged.|
You can see the leaf roller worm right about in the center of that last picture. (You'll also notice what I believe to be a sweat bee, no concern to the filberts.) The worst damage the leaf rollers do is sever the new growth as you can see in a couple of these pictures.
If you notice any damage at all in your new filbert planting please talk with your CPS fieldman.
