        Great fungicide
        [This review was collected as part of a promotion.] This worked wonders for my indoor plants for fungus growth. The value of this product supercedes the more expensive fungicides at the store. The product is versatile in the sense of being able to use all types of plants and even safe for veggies.

          [This review was collected as part of a promotion.] This fung-onil fungicide from Bonide is really nice. This fungicide is perfect to control any plant disease on your vegetable,fruit, trees, flower, shrubs, and much more. This fungicide helps with leaf spots, rust, blights, fruit rot, mildew, scab, mold, and more plant disease. I always purchase fungicide for my inside and outside plants and this brand is well known and I love using their products before. I am glad I receive this and plants will be very happy to be disease free. I actually going to treat all my outside plants with this and I know some of them do have leaves spot and rust so this will help.
            Great if needed.
            [This review was collected as part of a promotion.] We've used this product before and it actually works if you need it. I wouldn't use it unless necessary so it's a great product when needed. Highly recommend for your garden.

                Fung-onil Fungicide Concentrate
                [This review was collected as part of a promotion.] This is such a great thing to have if you garden! I’m currently growing a fig tree and they are susceptible to rust, so this is super handy! I would totally recommend this product to others so that you don’t lose your plants due to a fungus!
                  Wow - worked wonders on my Indian Hawthorn!
                  I planted two Indian Hawthorn's earlier this year and one quickly deteriorated. It took me a long time to realize it was a fungus and not over/under water or sun. I have only applied this twice to the plant and it has improved SO much in just a couple of weeks. Night and day difference. I am so pleased with what this has done so far! Fingers crossed it continues to improve and the plant is saved. I wish I had taken a before photo to show what it looked like before. Brown leaves everywhere, no new growth, and leaves falling off in waves. There are still signs of the fungus but this is massively better and new leaves are starting to grow back!

                    This fungicide worked wonders on my tomatoes after they had been in serious decline from Septoria leaf spot.
