  • Blueberry Scorch Disease
  • Phomopsis Twig Blight
  • Blueberry Shock Virus
  • Anthracnose

Blueberry bloom is progressing nicely and bee activity seems reasonably good. Our biggest enemies are wind and cold. Botrytis does not seem to be developing in blueberry fields and should not pose any risk in the next 7-days. Anthracnose is our biggest disease concern at this point. Hopefully all conventional growers will have made one application of Ziram and will be looking at an application of Abound next week.

Malathion Blueberry Label

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.

Oriental Fruit Moth Update

In southern counties we have accumulated approximately 102 DD base 45 since the biofix set on 4/16. Based on the current forecast, insecticides  for OFM control should be applied  in 7-10 days. In northern counties, only 14 DD have accumulated since the biofix set on 4/22 so no applications for OFM will be needed for about 2 weeks.
