Q. I have been hearing about a new fungicide to control late
blight on tomatoes called Serenade®. Can you tell me more about it?
Serenade® is a biological
fungicide (biofungicide) that has a
broad label to suppress and control many key diseases of
fruits, vegetables and ornamental plants, including late
blight on tomatoes. Biofungicides such as Serenade® are
made from beneficial microorganisms such as bacteria and
fungi. The active ingredient in Serenade® is the QST 713
Strain of Bacillus subtilis.
