IPM Message for Cranberry Growers: Jun 27, 2013

June 27, 2013

Things seem fairly quiet so far. State Bog is 60-80% IN bloom. The Stevens at Rocky Pond Bog in Miles Standish are 5% out-of-bloom. At State Bog, the Ben Lears were 25% out-of-bloom and the Early Blacks were 13% out-of-bloom mid-week. For new hybrids and some early cultivars, recommended spraying for cranberry fruitworm control is at or close to 50% out-of-bloom so you should be collecting data now so you don't miss 50% out-of-bloom. It is time to fertilize with your bloom time application. If you are using sulfur for pH remediation, make sure you are applying when the bogs will be dry. Puddling and sulfur will injure vines. 

People have been reporting leaf miner moths on their bogs, but we have no control options to offer. Green spanworm moths have been flying. Hoplia, oriental beetle, Equina, and cranberry root grub adults are also flying now. 

Frank is off to the Left Coast. Good luck, Frank!
