Ortho MAX Garden Disease Control Concentrate, 16-Ounce (Active Ingredient 29.6% Chlorothalonil Fungicide, Formerly Known as Daconil. For use on Vegetables, Fruits, Flowers, & Ornamentals.)

We try to avoid using too many chemicals in our yard, but nothing was working to prevent leaf spot on a number of large photinia in our yard that act as a privacy screen. Once the leaf spot takes hold, the leaves all die off and you're left with an ugly mess until the next season when the leaves grow back, only to get the disease and fall off again. We tried various sprays and methods before buying this and nothing worked. This stuff worked/works great. Not only does it prevent the leaf spot from spreading but in our experience it actually got rid of existing leaf spot, which from what I had been reading was not really possible. I go out and spray with a hose-end applicator about once a month (maybe twice a month during the prime growing season in spring when there's a lot of rain), and it keeps the leaf spot from coming back.

Seems to work well as preventative treatment. Have tried on a number of plants and did not cause damage like you get with some similar products

I had fungus issues with my blue spruce pines and also with my box shrubs. Applied Ortho 3 times (once a month) with very positive results and fully recovered pines/shrubs. Great product!

I have used this product before and it performs very well. Ortho is a good product overall.

Was using a different plant care product for black spot on my roses (something with neem oil) that simply wasn't working. I wasted a lot of time trying to use that and lost all the leaves on my roses. After using the Ortho Max Garden Disease Control consistently, they completely healed. I did use it more frequently than what the directions indicated until it was gone but the plants have bounced back 100%. It definitely did the job.

Didn't work. Lost everything to a fungus. Had to chop everything down and start over.

Works great for tomato blight/early blight. We have had a ridiculously wet season. Blight started on my plants only 2 weeks after planting. Even though I moved them to a new location than they have been before. The main product chorothalonil is what I found recommended for blight from the Purdue website. First I pruned off what was showing signs of disease and then follow the product directions.

Plants are doing better. Too much rain lately so I can't really tell. After three applications blight is still present.
