I’ve had a sickie (now I have 3..) and I bought a systemic fungicide for treat it.
Someone have experience with the following product?
www.gesal.ch//ch/de/products/Gesal-Langz...z-FOLICUR-Spray.html

I want to use for 3 times with 20 days interval. It’s ok, or should I shorten and do every 14 days?

Folicur by Bayer, right?
"A systemic fungicide emulsion, oil in water for the control of the diseases mentioned on the crops listed. "

I guess every 21 days is safer.

To see the "crops listed", you should download the PDF of the label:

I hope it helps

Thanks Clicio Gesal, but It’s in the Bayer family also what I know. Oki, I’ll do 21 days interval 3x.
