Works better than other fungicides I have tried. Saved my cucumber plants

Works better than other fungicides I have tried. Saved my cucumber plants
I grow English cucumbers indoors. Each grow went well for a while until the leaves started getting yellow-brown spots that eventually killed the leaves. This disease also dried and killed the developing cucumbers. Through research, I found out this was caused by a bacterial disease called leaf spot or angle spot. I tried a couple of other fungicides that didn't work and I lost the plants.I discovered this fungicide on a YouTube video and decided to try it. Cucumbers are very prone to leaf spot that develops in humid and/or warm environments. Since I am growing these cucumbers indoors, the environment is both warm and humid. It is recommended that cucumber plants are sprayed for leaf spot once a week to control/eliminate this disease.I have been spraying my cucumber plants once a week with a solution of the fungicide and new leaves don't have leaf spot. I have also noticed that the plants are starting to develop healthy cucumbers. I plan to start a new pot of cucumbers and spray them once a week with a solution of this fungicide to prevent leaf spot. Since this fungicide has worked so well on leaf spot where others have failed, I assume it will work well on other fungal and bacterial diseases. The downside of using this fungicide is that labeling on the product warns not to use it on greenery that is fed to animals as it is toxic. Since it is recommended for cucumber, tomatoes, green peppers, etc., I am assuming that it washes off of any produce it gets on. I will update this review with the results.UPDATE 04/13/24:Since the previous review, I have started 2 new pots of cucumbers and have been spraying them with this product as they grow. I have been using a 1 quart spray bottle and add 3.8 ml. to a quart of water. Although I see a couple of spots on lower leaves, spraying 1-2 times a week has kept leaf spot under control. For this grow, I am seeing a lot more baby cucumbers and none of them are drying up as they did in the previous grow. I have also been using this spray on my yellow squash and zucchini which are also susceptible to leaf spot. They are also doing much better.This spray has had no adverse affect to the produce on the plants sprayed, but I do recommend washing produce from the sprayed plants just to be safe.I hope this review was helpful for you.

This worked very well to eliminate powdery mildew on my zucchini plants. It had clear and easy instructions on how much to mix per gallon depending on the plant and application purpose and it was easy to measure it out. It mixed with the water easily but I did find that you need to shake up the mixed suspension as to it will settle to the bottom of the sprayer after several days. Other than that I am very happy with the results.

When I'm outside, people stop on the road to compliment me on my flowers. When it rains, I bring my hanging baskets under the porch to preserve the blooms. Having invested all that time, money and effort, I want to take care of them. However, when the heavy rains come, my giant marigolds, roses, and heirloom tomatoes start to get black spots. Left unchecked, the plants start to turn black and die -- unless I use the Daconil. I've tried other products, but this is what seems to work the best. As long as I don't forget to sprinkle it over my flowers, black spot and mildew is not a problem. I find that it's a better preventative than a cure. In other words, it's best to apply BEFORE a problem arises, or BEFORE extended rainy periods, rather than afterward. I like the fact that it only needs an hour to dry before it becomes rainproof. That way, I don't have to keep re-applying with every storm. This stuff really helped my tomatoes to grow big and beautiful, without any blackness wanting to form around the stem.

I used this product based on a recommendation from the succulents sub on Reddit, and am glad I did. Daconil, in combination with 70% isopropyl alcohol, eliminated powdery mildew on succulents with a fighting chance. I did this as an experiment, but found the PM would return overnight on advanced cases on smaller plants. Those with advanced cases (that arrived to me from Best Plant Friend) did not and were tossed out. I believe that Daconil and isopropyl alcohol saved the larger plants that it spread to without serious cases. In my opinion, this is a big win as too often these plants are a total loss. Many people believe these plants need to be thrown out regardless, but I have too many valuable succulents to do so. Due to irresponsible nurseries, I have experienced nearly every pest and disease known to succulents and houseplants. I have learned how to spot signs immediately and how to act quickly, and thanks to products like Daconil I can have a fighting chance.

I use this on several different plants and it works great. Amazon has the best price around on it.

After trying a couple fungicides without success. I read an article about a fungus attacking Pyracantha plants.
The plant would blossom but then the berries were turning black. One branch was completely destroyed by the fungus.
This was the first year the berries started to come out. But it takes continuing spraying the ground and the plant.
The the ground in early spring is important to kill the fungus before it creeps up the plant. The fungus goes into the ground for the winter..
This product Devlon really works and bring my plant to life again.

Made to sound like it will prevent or STOP tomato blight.....but I haven't noticed it making any difference . I've heard that once the blight in in the soil, there is NO getting rid ot it. I'm starting to understand that. Have had it every year for the last 7-10 years and this product has not yet stood up to it's hype.
