Gravex 20EW Fungicide (16oz) - Myclobutanil Concentrate

I grew 350+ zinnia flowers, all from seed, in both pots and in the ground. The one's in the ground are in the front of my house and the pots are in the back. They were healthy and strong and beautiful until the end of August or maybe into September when they quickly were overcome by Powdery Mildew. It may have been in the plants a while, but the powdery visual symptoms came on pretty fast. In a week or two, ALL the leaves were completely covered in this horrible stuff. By he time I did my research and bought this product, some of the plants had outright died, although most still had nice flowers and even new buds coming out every day on their browning stems. I wanted to enjoy them a while longer, but mostly wanted to eradicate as much as I could so the spores wouldn't turn up next year. Well, this stuff did the trick. I mixed and sprayed everything at 2ml per gallon of water. In the potted plants, I saw improvement within 24 hours. After after 3 or 4 days, it was mostly all gone. During that time, there was no rain to wash the leaves, but it was windy. In the front where the flowers were in the ground, they got a double dose because I wanted to use up what I had mixed. I am talking about hundreds of flowers, many 6.5 feet high but most 3-5 feet tall, planted 18" apart, so the double dose was warranted to get everything anyway. The effect was slower. Maybe there wasn't as much wind or maybe being in the ground had something to do with it, I don't know. I saw improvement after a few days. Now it has been a couple weeks and the season is about over, but after a rain yesterday, most of the visible PM is gone in front. I'd estimate 80%, and what is still there may actually be dead. My plants took a beating, but not from the fungicide - that seemed to have no affect on the plants overall health. Next year I will inoculate them with this stuff early on and maybe rotate to another systemic to avoid the PM building resistance. I know this chemical can be controversial, but used responsibly, I decided it's ok, and I'm glad I did. I did not plant almost 400 flowers from seed so my wife could watch them get ravaged and diseased. Thank you, Gravex!

It works great just follow the instructions

I bought this specifically because of Plumeria Rust on our trees. I used general fungicides, but I read this one was best for plumeria. It does not do much for the leaves already under attack, but it does a good job of preventing infection of new leaves. Once we get through a full leafing cycle, we should be good. It does have a strong smell. As a concentrate it is easy to use and easy to apply using a backpack sprayer.

Orderd to treat peaches for Brown Rot since I lost so much of my last crop to it. This time I started using it just a couple of weeks before harvest (that was when I finally was able to figure out what the culprit was, how to treat it and found this product) and only found one or two peaches with brown rot, a HUGE difference over last time. So I’d say it works! We’ve always had a lot of fungus here where I live and this year we’ve gotten tons of rain so only 1 or two out of several dozen peaches is a win.

Worked well

I got just what I ordered and it arrived just when they said it would.

Used for my fruit trees easy to use

Works pretty well on my rusty roses.
