Mummy berry forecast Thurs. May 12th 2011

Knox, Lincoln, Waldo and southern Hancock counties

Mummy berry cups were likely present in cooler, later fields from Monday May 9^th through Wednesday May 11th. In most fields, the cups will likely have finished up later on Wed. May 11^th. On Thurs. May 12, the cups were done in Union, Liberty and Belfast areas. I am estimating that most cups are done in these areas since the Belfast field is a later, wetter field.

There were infection periods starting on Monday and Tuesday. There was an infection period from the evening of Monday May 9^th through the morning of Tuesday May 10^th. There was another infection period on Tuesday May 10^th 11am to noon through to Wed. May 11^th early morning to 9am .

If you have applied fungicide on or after Wed. May 4^th your plants would have been protected during these infection periods.

If your plants were not protected and you still had cups in your field through Wed. May 11^th, then you have until Thursday May 12^th evening to apply fungicides to kill off any infections on Monday, and until Friday May 13^th afternoon to kill off any infections that happened on Tuesday.

Northern Hancock and Washington counties.

There were active mummy berry cups from Monday May 9^th through Wednesday May 11^th in Deblois and Jonesboro, and later, cooler fields likely still have active mummy berry cups.

Infection periods started on Monday and Tuesday of this week. The first infection period occurred from Monday May 9^th 2 to 3pm through Tuesday May 10^th 6 to 7am. The second infection period occurred Tuesday, May 10th from 8 to 9am through Wednesday May 11^th midnight to 7am.

If you applied fungicide on or after Wednesday May 4^th morning your field was protected for all of the infection periods from Monday through Wednesday.

If your plants were not protected, then if you have applied fungicide before Thursday May 12^th your plants will be protected for all of the infection periods.

Applications of fungicide before Friday morning will kill off any infection that occurred in the 2^nd infection period from Tuesday to Wednesday.

Applications of fungicide after Friday morning will protect plants into the future, but will not be within the time to kill off any infections that occurred in these last infection periods.
