Those of us in Northern Virginia will have a 40% chance of rain tomorrow (Tuesday, 4/13/10) afternoon.  The temperature expected will be in 50’s.  It will take about 7-9 hours for Phomopsis to have an moderate level of infection. Black rot will take about 12-24 hours to infect at that temperature range, so, if it rains and persists, there is a chance for Phomopsis infection.
