As of April 1, there are 5 points out of a possible 10 that favor keeping quality for the 2010 Massachusetts cranberry crop. The 5 points were awarded for favorable sunshine hours from the previous year (4 points) and 1 point was awarded for favorable sunshine hours in February. The forecast is for GOOD keeping quality. The final keeping quality forecast (issued after June 1) could be upgraded if we have a cool and dry April and May. Based on the present forecast, fungicide applications and the rate of fungicides applied could be reduced.
As for the holding of late water, because we are currently two weeks ahead of normal plant phenological development, it is too late to start flooding for late water unless the bed was already flooded in the heavy rains of March 29-30. If the bed still has a significant depth of water, the vines should be totally submerged (see page 3). As for flood duration, call Carolyn DeMoranville (x 25) for advice. Check the section on late water in the Chart Book for advice regarding general information on this cultural practice. If you have any questions regarding the forecast, please contact Frank Caruso at x18.
