    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 ;) .....

    It works

    By Paul on 09/24/2023

    Verified Purchase

    This product works but is very restrictive in its usage. You cannot use it on residential lawns, near schools, apt buildings. I use it on a golf course for a client. Some of my other residential clients has ask me to use it and I refuse because I don't want to get in trouble if anything goes wrong. I bought it primarily because of the price.

    Good product, good price

    By Jerry on 05/04/2024

    I built a putting green in my backyard several years ago. This product has been an affordable alternative to name brand products. It works as expected for disease control and it doesn't break the bank.
