2,4-D Injury in Blueberry #134758

Asked June 17, 2013, 9:12 AM EDT

I applied bush-killer to kill the blackberries in and around my blueberries. Now the blueberry leaves are crinkled and curled. Is this herbicide damage from my spray?

Kalamazoo County Michigan

Expert Response

That is 2-4,D injury. If you used an ester formulation of 2,4-D was most likely caused by vapors from your herbicide application. The plants will grow out of it if the dose is not too high. When the new emerging leaves look good the plant has recovered.
