Ashland ME NoBlight Table

Your late blight fungicide spray dates — optional

You can enter the most recent date on which you applied a late blight fungicide to see an estimate for the next recommended spray date.  You can also enter multiple spray dates to see if there were protection gaps.  Type the month and day of each spray date, for example: 8/5 or 08/05 into the yellow box below.  The year is assumed to be this year, so you do not need to enter a year value.  You can also enter a date as the full month name or 3-letter month name abbreviation and a day number (e.g. August 5, or Aug 5).  The page automatically updates when you add, delete, or change dates.

Privacy:  The dates you enter stay on your own device and do not leave your web browser.  Your browser will remember the date(s) you enter for the next time you visit this page.  If you want to erase the dates you entered, use the Clear All Dates button below.

If spray dates were entered above, in the “Current Late Blight Protection Status” and “Assessment” report boxes below, dates prior to the first spray date are ignored.  The estimated date for when late blight infection risk began at this site based on the potato emergence date provided is highlighted in green shading in the Spray Date column.

Current Late Blight Protection Status:

If spray dates were entered above, you can choose which dates to show in the table below.
