Mummy berry forecast for Mon. May 9th 2011

Knox and Lincoln counties

Mummy berry cups were present on Thursday at Union so they likely lasted over the weekend.

There was a chance of an infection period in some areas with rain and then fog from Thursday May 5^th night around 5pm to Friday May 6^th early in the morning.

Otherwise there were no infection periods during the weekend in these counties unless you have a field with heavy fog that lasted at least 8 hours.

It is too late to apply fungicide now to kill off any infections that occurred on Thursday. I would only recommend applying fungicide if you are sure your field had fog for more than 8 hours one evening this weekend AND you have not applied fungicides since Saturday April 30^th.

Waldo and south Hancock counties.

Cups were still present on Monday in Belfast and Liberty and are probably still active throughout this area. I expect the cups are likely to finish up this week. The rain was not long enough on Thursday night to cause an infection period in this area.

There was an infection period from Saturday May 7^th, 2011 8pm to 9m through to Sunday May 8^th from 7 to 9am in these areas.

If you had applied fungicide on or after Saturday April 30th then your plants would be protected during this infection period.

If your plants were not protected then you have until Tuesday May 10^th about 8pm to apply fungicides and kill off infection from the last infection period.

Northern Hancock and Washington counties.

There are still mummy berry cups being produced at Deblois and Jonesboro, and cups are likely to be producing spores at Jonesport and other later fields.

An infection period occurred from Thursday May 5^th 3pm to 6pm through to Friday 8 to 9am in Deblois and Jonesboro. In Jonesport, the temperatures were cooler so the conditions were borderline for producing an infection period and only some fields may have had an infection period.

There was an infection period in SOME areas with heavy fog from Sat. May 7^th 11pm to Sunday May 8^th at 7am. This infection period was seen in Jonesboro and Jonesport, but not at our site in Deblois.

The fog was not long enough overnight from Sunday, May 8^th to Mon. May 9^th with the cool temperatures to allow the fungus to infect the plants so there was NOT an infection period.

It is too late to apply fungicide now to kill off any infections that occurred on Thursday night.

If you applied fungicide on or before Sat. May 7^th your field was protected in the possible infection period from Sat. May 7^th to Sun. May 8^th.

If your plants were not protected AND your field is one that typically gets heavy fog, then you have until Tuesday, May 10^th at 11pm to apply fungicide and kill off any infection.
