We were just notified on late Wednesday afternoon that the Gowan 24C label was approved for use in NJ blueberries. This label is for the Gowan Malathion 8 Flowable, and gives us a maximum of 2 applications at 2.5 pt (lb ai) per acre, with a 1 day PHI. See label NJ Malathion 8 Flowable
We are still waiting on the Cheminova and Loveland labels.
