2006 Final Keeping Quality Forecast

The Keeping Quality Forecast for June 2006 is for FAIR keeping quality.

We calculated 4 of a possible 16 points to arrive at this forecast.  This is the first year we have had so few points since 2002 (when we had one point!).  We were awarded 2 points for March sunshine, 1 point for March precipitation, and 1 point for April precipitation.  This is a year that you should not reduce your fungicide rates and/or the number of fungicide applications.  However, if you have a bed that had late water held this spring, you can reduce your fungicide inputs in that situation. 

2006 Preliminary Keeping Quality Forecast

As of April 1, there is only 1 point out of a possible 10 that favors keeping quality in the 2006 Massachusetts cranberry crop.  The lone point was awarded for favorable rainfall in March.  The forecast is for POOR keeping quality.  The last time we had such a low point total was 2002 when we had zero points.  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.  Due to the decent condition of the vines coming out of the winter and the ample quantity of available water, this would be a good year to consider holding late water.

2005 Final Keeping Quality Forecast

The Keeping Quality Forecast for June 2005 is for VERY GOOD TO EXCELLENT.

We calculated 7 of a possible 16 points to arrive at this forecast. This is the third year in a row that we had this total. We were awarded 2 points for March sunshine, 2 points for March temperature, 1 point for April precipitation and 2 points for May temperature. This was the second coldest May ever recorded at the Cranberry Station. The mean temperature for the month was 50.9 degrees F; the only May that was colder was 1967 when the mean temperature was 49.3 degrees F. This is a good year to reduce your fungicide rates and the number of fungicide applications. However, if you have a bed that has had above average rates of fruit rot during the past two growing seasons, I would proceed with the normal three fungicide application program. As usual, call me if you have any specific questions or concerns about a particular bed.

2005 Preliminary Keeping Quality Forecast

As of April 1, there are 4 points out of a possible 10 that favor keeping quality in the 2005 Massachusetts cranberry crop. Two points were awarded for favorable sunshine hours for the month of March and two points were awarded for a favorable March mean temperature. The forecast is for FAIR TO 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 possibly be reduced except in those beds with a history of above-average fruit rot. Due to the decent condition of the vines coming out of the winter and the ample quantity of available water, this would be a good year to consider holding late water.

2004 Final Keeping Quality Forecast

The Final Keeping Quality Forecast for June 2004 is Very Good to Excellent. We calculated 7 of a possible 16 points to arrive at this forecast. This is identical to the total for 2003 except that 4 of the 7 points last year were in the gray area (previous year’s sunshine). This time we had a ‘no doubt’ 4 points for sunshine in 2003. We also were awarded 1 point for March precipitation, 1 point for April precipitation and 1 point for May precipitation. Dry springs are always good. However, this spring was too warm for any points to be garnered for temperature. This is a good year to reduce your fungicide rates and the number of fungicide applications. However, if you have a bed that has had above average rates of fruit rot during the past two years; I would proceed with the normal three fungicide application program.

2004 Preliminary Keeping Quality Forecast

As of April 1, there are 5 points out of a possible 10 that favor keeping quality in the 2004 Massachusetts cranberry crop. Four points were awarded for favorable sunshine hours for the previous year and one point was awarded for favorable March precipitation. 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 (it certainly has not started out being dry!) and May. Based on the present forecast, fungicide applications and the rate of fungicides applied could be reduced except in those beds with a history of above-average fruit rot. Due to the miserable condition of the vines coming out of the winter, this is not a good year to hold late water. 

2003 Final Keeping Quality Forecast

The Keeping Quality Forecast (KQF) for June 2003 for GOOD TO VERY GOOD. We calculated 7 of a possible 16 points to arrive at this forecast. This is the most points we have had sincewe had 8 points in 1997. The factors that contributed to this year's forecast were: (1) 4 points awarded for sunshine from 2002 as discussed in the April 2003 newsletter; (2) 2 points awarded for March sunshine hours; (3) 1 point awarded for May precipitation. have never seen so many close calls for some of the other point getters. We missed getting 2 points for April temperature by 0.2o. We missed getting 1 point for April precipitation by 0.03 inches. We missed getting points for May temperature by 1.4o. Because of all of these near misses, I am confident that the keeping quality will lean towards being very good. This appears to be a good year to reduce your fungicide rates and the number of fungicide applications. However, if this cool and wet weather continues, these are ideal conditions for fungal infection. You should keep that in mind as you plan your fruit rot fungicide programs. As usual, call me if you have any questions or concerns. We will be looking very closely at the current KQF this year in a project funded by the USDA/CSREES Pest Management Alternatives Program. We'll have more to tell you about after this growing season concludes.

2002 Final Keeping Quality Forecast

Thank goodness for the rainfall in April, where-in we did not come close to the normal 6.7 inches that falls that month. As in 2001, rainfall in April accounted for our only point of the sixteen possible keeping quality points. Consequently, the June 1, 2002 Keeping Quality Forecast is VERY POOR (as it was last year). Both April and May were warmer than desired and the May rainfall exceeded the desired amount for additional points. Consequently, this is another year you will need to be very careful with your fungicide usage, particularly if it is a bed for fresh fruit. Fruit quality will be sacrificed if you reduce your fungicide use drastically. Be especially conservative in those beds that were not managed and sprayed with fungicide last year or in those beds that had significant fruit rot/scald (especially Stevens for the latter). If the summer months are hotter than usual, if there is drought stress, or conversely, if it is a very wet season, we will not see any improvement in the forecast. Things will remain as they are predicted. One of these years, I hope we can return to a decent KQF!

2001 Final Keeping Quality Forecast

As a result, this certainly was a good year to hold late water and I know many of you did so onyour acreage. You will need to be very careful with your fungicide usage, particularly if the fruit is destined for fresh market. Fruit quality will be sacrificed if you reduce your fingicide use drastically.

If the summer months are hotter than usual, if there is drought stress, or conversely,if it is a very wet season, we will not see any improvement in the forecast. Things will remain as predicted.

2001 Preliminary Keeping Quality Forecast

As of April 1, there are 0 points out of a possible 10 that favor keeping quality for the 2001 MA cranberry crop. The forecast is for a VERY POOR keeping quality. The final forecast could be upgraded if we have a cool and dry April and May. Based on this present forecast, this would be a partiuculaarly good year to hold late water. Unless the forecast improves in June, we do NOT recommend cutting corners on fungicides applications or rates for fruit rot management, particularly in a bed that has a history of higher fruit rot incidence.

Thank goodness for the drought that began in April where no measurable rainfall occurred for 33 days. Rainfall in April accounted for our only point of the sixteen possible keeeping quality points. Consequently, the June 1 forecast is for a VERY POOR keeping quality for the 2001 Massachusetts cranberry crop. Both April and May were warmer than desired and the May rainfall exceeded the desired amount for additional points.
