Works ok
[This review was collected as part of a promotion.] Ive never used anything on my plants before, so I wanted to try the Daconil Fungicide concentrate. I have a lot of animals that tend to destroy my plants and end up making them die. With the daconil, you have to make sure you use the right amount and mix it with water to dilute it. You then softly spray it onto the plant. The liquid first looks like white paint in the container, then when you mix it with water, it reminds me of milk. I did noticed that it dried white on my plants, so make sure you really do rinse your plants/veggies/fruit you get off of them. I didn't really notice anything different with my plants, maybe ill use it longer and see how it works better. Maybe im just doing something wrong.

Great brand
[This review was collected as part of a promotion.] This is definitely a good brand and I have found that it is working well on my plants in my front yard, from what I see so far it's doing exactly what it is supposed to.

Amazing Preventive
[This review was collected as part of a promotion.] Daconil Fungicide Concentrate is extremely easy to use and works as a wonderful preventive! In my areas many of us have fruit trees and plants growing. Because of cross pollination if one tree gets a fungal infection it seems everyone does. We have been using this for years and we have always had the largest crops in our neighborhood. Pears, grapes, red raspberries, blueberries and peaches all flourish and remain healthy.

Haven't seen any difference
[This review was collected as part of a promotion.] I put this on some plants that were somewhat fading in my house but I haven't noticed a difference in their appearance yet. Maybe it takes a little longer?

Truly saved the life of my rose bush!
[This review was collected as part of a promotion.] I have a rose bush in my front yard , every year it developed some sort of a fungus or illness. This year we actually thought about removing it because nothing would work. When it wanted to bloom, the roses would shrivel up and die off. I received this product and decided to give it a try after using different products that did not work. Within a couple weeks it was like "WOW"! I have never seen this many roses on the plant before. It is beautiful and absolutely full of flowers. Best of all, it is not done blooming! After doing more research on this product it is great for over 75 diseases. It is even good for for fruits and vegetables! I highly, highly recommend giving this a try. It exceeded my expectations.

Great stuff
[This review was collected as part of a promotion.] I've been looking for something to help my roses and my vegetables when I received Daconil. It seems that my rose bushes and tomato plants struggle every year so I'm excited to see how well Daconil works for preventing the mold but not harming the plants. It's very easy to mix up in my garden sprayer which is a plus. So far all of my roses are looking better and I will be using it on the tomato plants later in the month.

Saved my Roses!
[This review was collected as part of a promotion.] My Rose's have been suffering from a weird fungus for years. I have tried many antifungal products but they never made a difference after weeks of use. I added 3 tbsp of this product to a gallon of water. I have only used it for 3 days in a row and already see a difference! It treats over 75 difference ailments for plants! I am also going to use it on my flowering fruit trees now that I know it surely works miracles.
