IPM Message for Cranberry Growers: Aug 21, 2009

August 21, 2009

Things seems pretty quiet for this time of year. No unusual levels of fruit rot to report. If you have concerns about fruit rot management, please call Frank at ext.18. We have had a report of cupping of the top growth of Howes vines, possibly from QuinStar. If you have noticed any injury with QuinStar applications, please call Hilary at ext 21. We are now nearing the end of the time to be putting out bud set fertilizer applications if that is part of your program.

We could get hit with some decent rainfall this weekend from Hurricane Bill. If you have new plantings, you may want to raise the water level in your ditches to help minimize run-off. For most situation, the past week has been very stressful in terms of water use for the vines, so some rainfall could really be helpful.

I will update the message as needed until May 2010, when we will resume weekly updates. Thank you for using the IPM Message on the UMass Cranberry Station Web site.
