Weather data for Monmouth ME.  Forecast values begin October 6, 2008
Potential preharvest weather influences on
Storability, Drop, Color, and Scald risk
The August mean temperature was more than 1 degree F below the long term average.  Observations in Western NY have associated below normal August temperature with increased susceptibility of fruit to Low Temperature Injury during CA storage.  No hot dry spell in August-September.
     The McIntosh 10% drop date was not estimated because the observed date when McIntosh reached starch index range of 3.5 to 4.5 was not available.
     Weather conditions that promote optimum fruit color begin Tuesday, October 7
Weather data indicate 165 chilling hours will have accumulated by Saturday October 04.  Research found that 500 ppm DPA for Cortland & 1000 ppm for Red Delicious  is adequate for fruit harvested on or after October 04, and kept in Refrigerated Air storage.  Limited data suggest that same may also be true for McIntosh.  This is also the best guess for scald risk in Controlled Atmosphere storage.
Date Estimated cumulative hours below 50 F
