| Weather data for Monmouth ME. Forecast values begin October 30, 2009 | ||
| Potential preharvest weather
influences on Storability, Drop, Color, and Scald risk |
||
| As of October 30, weather data do not suggest increased storage risk due to low average August temperatures, or to hot dry periods in August or September. | ||
| General
outlook (no account for crop load, drought and other stresses) for when drop
of sound non-spur McIntosh apples might reach 10% of crop is Friday, September 18 to Saturday, September 26. |
||
| Weather conditions that promote optimum fruit color begin Monday, September 14 | ||
| Weather data indicate 165 chilling hours will have accumulated by Wednesday September 30. Research found that 500 ppm DPA for Cortland & 1000 ppm for Red Delicious is adequate for fruit harvested on or after September 30, 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. | ||
