Fort Fairfield ME NoBlight Table
Your late blight fungicide spray dates — optional
You can enter late blight fungicide spray dates to see estimates for the next recommended spray date. Type the month and day number of each spray date, for example: 8/5 or 08/05, into the yellow box below. The year is assumed to be this year. You can also enter dates 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 change the dates entered.
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 this browser no longer has the spray dates you entered before, paste your saved copy of them here and click on the Load Dates button.
Your browser remembers these dates on this device, but that memory can be cleared, so keeping your own copy is recommended.
The rainfall values used in this table come from NOAA gridded weather data which are usually a better estimate across a farm than using a single onsite rain gauge. But if the gridded value is 0 when there was observed rain, then the model performance can be enhanced by entering that non-zero rain amount. Likewise, if the gridded data says there was rain and you are sure none actually occurred on your farm, then you can replace that false rain amount with a 0. The table below will update to show where the rain amount you entered has affected the model output. The altered rain amount does not affect the calculation of daily or 7-day DSV. But it can affect calculation of the spray interval.
