IPM Message for Cranberry Growers: June 17. 2016
Bloom is coming on slowly in some areas. With mixed varieties, time the start of fungicides with the earlies. Since we are in that situation, we will be applying our first fungicide today. Our program will consist of 2 applications of Proline and the third as Bravo. All at the full rate. Recent sweeps yielded a few weevils, span worms, and large gypsy moths. None over threshold. We have seen and gotten reports of wilt or flagging uprights. They may recover if the water loss was not too severe.
Cranberry is not on the label for the new Roundup gel, so it is NOT legal to use it on bog.
We do not recommend combining callisto and bravo as a single spray. Do callisto first, allow to dry, and then apply bravo.
