Chlorothalonil 720
By Dana on 06/07/2017
There are two types of fungicide--systemic, that are absorbed into the plant, and "blockers" that help prevent fungus spores from damaging the plant. Chlorothalonil is a blocker, and despite my doubts about a "blocker" working, it definitely kept a fungus attack from expanding. So I give it 5 stars. You should consider using a systemic fungicide "every other time" to keep the disease from developing a resistance. Also, customer service at DoMyOwn is five stars+.

Great contact fungicide
By Jerry on 09/26/2020
I used this at 1/2 rate with a 1/2 rate of Ppz / Azoxy..... In my TTTF, I had been using the Headway type mix at 1.5oz/1,000 every 3 weeks since April, and still had disease smoldering in the crown of my first year grow in... Added this to my mix in mid August, and finally healed up all the fungus issues..... READ THE HEADWAY FUNGICIDE LABEL... It recommends this... none residential areas of course ;) .....
