Bonide Fung-onil Multi-Purpose Fungicide, 16 oz Concentrate

This is a great product. It has a slight milky soapy texture that clings to the plants so you don't want to use this before showing off your plant's. I have a continuing struggle with fungus every year because of the lack of sustained intense sun, so I always have to counter attack with new solarized soil and this fungal spray every year. I start every year now by treating the top of my soil with this spray a week or so before the first planting and it seems to help. I spray the plants lightly every week to keep things in check. I have never burned up my plant's with this product. I can usually control powdery white fungus without destroying the entire plant. But any time I get one of the black fungus' I pull the plant, scrape the top inch of soil and solarize it in a black garbage bag then dispose of it. It suck's having to deal with this every year but even if I get a half dozen fresh high quality tomatoes a year it's still worth it. I purchased this to refill my spray bottle of the the same brand. I wish the directions started with a simple explanation of how to mix this to refill the retail bottle. They supply very detailed directions for multiple applications including trees and bushes. A bit overkill for me but I'm sure someone appreciates it.

Worked for my tomato plants that were already infected with black spot fungus.

Bought this for the boxwood. It seems to help after a couple treatments but I also pruned out the dead branches and shook out all the dead leaves which were building up in the plant and growing some kind of mold. The combination seems to be working. The product looks like white latex paint out of the bottle so I had worries about staining and spots. Once you thin it out, it is still white but does not appear to leave white spots on the leaves.

This product works great at preventing fungus on vegetable plants (especially tomatoes) and perennials. This is the first year I tried it on my tomatoes (both in a garden and container). It's mid-summer and all the tomato plants that I treated are fungus free and are THRIVING. The one Roma that I did not treat in the early spring, has some type of fungus/blight. It now has no leaves, it's stunted, and has very little fruit. I also use it on my coneflowers and shasta daisy plants, which are prone to a black spot fungus. I apply the product as soon as the plants emerge in the spring and as needed if the weather is wet and humid. Prevention is the key. Once the fungus sets in, it’s very hard to control. Caution: Be sure to wear plastic disposable gloves because this product will burn if it gets in your eyes. It's hard to fully wash the product off your hands.

This stuff works. After spending 3 years and too much money purchasing chemicals in a attempt to save my shrubs from early blight or bacteria infection triggered by excessive rain, heat and humidity, Bonide Fungal Disease Control was recommenced by a well respected nursery in my area in April 2019. I sprayed every shrub including my roses and ground cover plants every 7 days. I noticed an immediate improvement after 7 days. After 21 days, the problem was solved and the shrubs are healthy and growing better than ever with a good plant food. In July I ordered another bottle on Amazon (Great Price) and gave all of my plants, including vegetables a preventative measure spraying. It has been extremely hot and humid in my area. No more neem oil, 3 in 1 fungicides. Some customers may complain that this product leaves a slight white residue on the leaves of some shrubs. I can with live it.

I have not found a better fungicide. It even can be used on fruits and vegetables and it works! No only that, but it worked beautifully on 3 day old seedlings that got a fungus! It’s that gentle but also effective! Amazing stuff!

This stuff is amazing. I've had some Indian Hawthornes for about 5 years and the leaves were covered with these hideous brown spots. I finally looked into it and found it was a fungus and to try this. After one application, within 2 days almost all the spots were gone. A few days later new leaves started growing. About a month or so later a few spots were still visible so I sprayed it again. They're now spot free. My parents borrowed some too for their roses and it worked great. If you have a fungus, I'm sure this will help and it's so easy to use.

You would need a lot of this product. It works slowly. It's ok. Price ok.
