Disease Control for Roses, Flowers and Shrubs, Concentrate, 32 oz, Makes 42 Gals of Spray Fungicide for Plants

It works for powdery mildew on roses! I tried to avoid a systemic and sprayed 4 times with various home concoctions I’ve seen touted online and none of them got rid of the mildew. Not even phased it. One treatment with this and I have blooms and green leaves again. If you have a lot of roses and live in a warm humid area this may be your only hope for a blooming rose garden.

I like planting petunias around the yard and while my Supertunias and Wave petunias grow great without any issues i have a flower bed with just regular petunia sp and they always seem to suffer from botrytis/mold after it rains. The flowers will look all melted and slowly the plants will die. I mix this up per the instructions in my 1/2 gallon pump sprayer and will give the flowers a good spray when the sun is going down before a rain storm. The pentunias are growing great. I still will have a few flowers I will pick off but over all im happy. I also have a big issue with powdered mildew on lilac bushes and sunflower leaves. The lilac bushes i will have to spray a few nights in a row but it does cut down on the powdery mildew significantly. I think by doing this is keeps my lawn looking better as a result. I have a small lawn so this bottle goes along way.

It's taken me a while to write this review but after a full year using it on my roses I still don't quite know if I liked it or not. It's very easy to use but my success has been so-so. I started spraying this on my roses leaves as soon as they started appearing, as instructed, and all growing season last year I faithfully applied the spray to my rose leaves every other week, as instructed. The photo attached shows that I still, despite consistent application, got spots on my leaves though I will admit the spots weren't as bad as the previous year. I also noticed, but forgot to take a picture of, was that as the season progressed the spots did appear less frequently and I even had a good amount of leaves with no spots, I hesitate to say this product solved the problem. It helped certainly and I'll continue to use it again this upcoming year but it wasn't a miracle product. Maybe I was doing something wrong, I don't know. I would rate this 3.5/ 5 as it does help the spotting to some extent but didn't solve it.

It helps a lot and save my roses. You have to use it 3days per week.

Works great

Works at my location on the south coast of Oregon.

Did not work well for us.

I have 2 different types of young arborvitae and a juniper that have fungus. I used copper fungicide that didn’t seem to do much if anything a few years ago. I used daconil last year that seemed to help a little maybe. Tried this a little over a month ago after almost giving up and it definitely made a difference. Sprayed the trees really well as always, under the foliage, sides, and then the top. Didn’t even pay attention anymore and noticed my emerald greens seemed to be growing which are slow growers. Went to look yesterday evening and the one with the most problem is fuller and the big dead spot is almost gone. My junior giants also filled out more and most of the black is gone. With just one application. Directions say twice a year two weeks apart. The fungus looks gone on my juniper but there’s a lot of dead on the branches that had the fungi, looks like a lot of new growth though. Going to need a lot of shaping. I still had some in my sprayer so I sprayed them again. Just don’t use them on vegetables. Directions forbid that. The new growth could be coincidence but there’s definitely a change. Try it yourself, if it doesn’t work it’s not the end of the world.
