Well, the rain yesterday took me by surprise, considering the weather forecast said very low probability for rain just hours before it started raining!

Waldo, Lincoln, Knox, Hancock and Washington Counties

There was an infection period overnight in all areas. Mature cups are probably still in most fields.  Please see the table below for approximately when the infection period started in our monitored fields.

If you applied fungicide on or after Tuesday, April 24, your plants were protected during this infection period.

If your last fungicide application was before Tuesday, April 24, you may want to apply fungicide again.

You have until 72 hours after the start of the infection period in your area to apply a fungicide and kill off any infection that may have occurred.

You will want to take into consideration if pollinators are in your field, in your decision to apply a fungicide.

NOTE: The North Ellsworth field had fog on Monday night that produced an infection period that lasted two days.
