The Keeping Quality Forecast for June 2015 is for GOOD keeping quality.
We calculated 7 of a possible 16 points for the final 2015 forecast. The positive forecast derives mainly from the low rainfall averages observed during April and May (2 points awarded). The Keeping Quality Forecast (KQF) should serve as a reference when making fungicide management decisions against fruit rot.
A GOOD forecast suggests that in beds with little or low disease pressure, 2 to 3 fungicide applications may be sufficient to control fruit rot this season. That is not to say that you should make all fungicide decisions based on the final KQF. Other factors such as disease pressure, drainage conditions, overall plant vigor, and plant varieties should be considered when designing your fruit rot management program. For example, beds with a history of fruit rot may require more fungicide applications for adequate disease control. Bear in mind that proper bog management (drainage, irrigation, and fertilization), practicing late water, and removing crop debris (trash floods) may also help in increasing fungicide efficacy.
If you have any questions about fungicide efficacy, fungicide resistance management, or need help in deciding which fungicides to use this year, please feel free to reach Erika at (508) 295-2212 ext.18 or via email at firstname.lastname@example.org.
