The preliminary keeping quality forecast is POOR.
As of April 1, there is only 1 point out of a possible 10 that favor keeping quality for the 2018 Massachusetts cranberry crop. The sole point was awarded for favorable sunshine hours for February (124 hr) which were less than the 50-year average for that month (143 hr). Consequently, the forecast is for poor 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 should NOT be reduced, and close attention should be paid where fruit rot has been a major or regular concern.
According to Carolyn DeMoranville, former Station Director, a poor keeping quality forecast would be reason to hold late water this year. However, if you see winter damage from not being under water in December and January, you should not use later water and now is the time to inspect for possible damage. Based on the current weather, you should not have to start late water particularly early. Late water floods should be applied prior to the breaking of bud dormancy. Generally, the 30-day LW flood will be applied between April 15th and 20th. Do not apply the flood if the buds have broken dormancy. See Chart Book for more information on late water floods.
