Sprayed Tomatoes with Daconil Fungicide


6/10/2020 – After 7 inches of rain over three days from TS Cristobal, sprayed the tomatoes with Daconil fungicide (Active Ingredient Chlorothalonil) at 1 Tbsp per gallon. Sprayed 2 gallons.

This was the first time to use Daconil in the garden. Daconil was recommended for vegetables that are close to harvest as Mancozeb has a 5-day harvest interval. Post Harvest Interval (PHI) for Daconil on tomatoes is zero (0) days.

There are some small black spots and some limbs that have lost all leaves and the limb is rotted. Cut them off.

Next spray will be in 7-10 days.


  1. Rec’d ACES email with a link to their page about Late Blight on tomatoes. The photos of it are what is happening in our garden that was the reason for the above spray. The 2020 SE Veg Growers Handbook (Handbook) accessed today, recommends Chlorothalonil in the weeks near harvest. That is confirmation that the above spray was the right thing to do.
  2. See TomatoDirt.com page Different Kinds of Tomato Blight and How to Tell Them Apart for photos of the different diseases.
