BonideFung-onil Multi-Purpose Fungicide, 32 oz Ready-to-Use Spray for Plant Disease Control, Controls Blight, Mildew & More

This worked very well. My roses were infected for quite a few years with these black spots on the leaves. It stunted the growth of the roses. After spraying this all over the rose bush, and cutting off all the leaves with spots on them, the roses are growing very well.

I sprayed this fungicide on my hibiscus bush twice now about a week apart in application to help control the spot fungus on the leaves. I have noticed that after the first application and removal of any yellow leaves, the spotted leaves were much less at the time of the second application. Currently, the temps are much cooler and the plant is covered so as to prevent frost damage and more fungus development.

This is the only product that has helped to save and revive my hydrangeas. There was a fungus that was spreading from one hydrangea plant to the surrounding ones until my whole garden was covered. By spraying this fungicide weekly, all of my hydrangeas have recovered and are growing healthy green leaves again. This is the only product I use now.

It's hard to use sprays on a tree taller than myself. Make sure to wear mask, gloves, and washable clothing. I planted a tree from a good nursery, and days later I noticed the dropping and wilting leaves like crazy! I was mad that they would not take it back, because it obviously came to me with the fungus. I treated the tree, and other trees within a short distance to prevent spread to my other fruits. It did take over a month with several sprays to stop the leaf wilt.

I should have paid more attention to the reviews. It is true that the sprayer only produces a very concentrated stream that doesn’t cover the plant well and wastes product. If I’m buying a pre-diluted product it is for convenience, and this removes that aspect. For the price of this and the extra spray bottle I’ll have to buy, I should have just bought the concentrate and prepared my own.I don’t know if the product itself works yet, since I haven’t been able to successfully apply it to my plants. But 3 stars assuming it does work.

I use this for fungus that sometimes grows on my seedlings. I don’t usually buy things that are ready to use. I always buy concentrates. However, when I need to spray just a couple of seedlings it’s convenient and I like that it doesn’t hurt my 1 week old seedlings when sprayed lightly at night and blotted with a paper towel. Haven’t tried it without soaking up the excess. It’s just that the seedlings only have their first leaves so I don’t want to overdue it. Bottom line - it has saved a lot of seedlings from fungus death. This is the kind of thing where if you don’t spray for the fungus immediately when you see it, 1 or 2 days later the seedling will be dead. So I feel very fortunate to have this product and at $9.99 it was well worth the price!

This really does work!! Used it on my Alberta Spruce trees… since they’re so ‘dense’, moisture gets stuck inside and they can get a fungus. It turns brown in places. I caught it early. My landscaper told me to spray it deep on the inside & then come out and it really does work! I started noticing a difference within a week I think. I’m reordering to treat some other trees. The only thing I don’t like, which others noted, is that there is not a fanned out ‘spray’ aspect… it dispenses only in a hard, direct, straight focused spray… Needs to have option of spraying in a true ‘spray’ fashion where it covers more area with each squeeze of nozzle. Hard on the hands.

Bought this because the first brand I bought to get rid of mildew did absolutely nothing despite multiple applications. Used this brand once and mildew never came back. Giving 4 stars instead of 5 because the sprayer doesn't work properly. Regardless of the setting you put it on it, it comes out in a stream instead which means you're using more product than you need. Will buy a small spray bottle from a dollar store and put the product in that.
