Daconil® Fungicide Concentrate for Insects 16 oz. - 100523634

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.

I sprayed my pear tree twice last year and now it is thriving. I thought it was going to die when the leaves started falling off and they had black spots all over them. This fungicide did the job and my tree is doing great now. Highly recommend this product.

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.

Why did you pick this product vs others?:We live in Western WA, and, unless you spray your trees for fungus - they will be dead in a year. Daconil works, and works well. Stopped a fungal infection on our peach tree on its tracks.

I love to use this on plants that have mildew and other fungi. It works great to clear up the fungus, and knocks off the bugs, too. This will last me all summer.

Worked as advertised. Directions for use were clear. Plants did well.

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.

Pleasantly surprised this stopped and actually reversed the disease our quaking aspens had. We’re in eastern Washington and it’s pretty common for nursery raised trees. Spayed the product in the Spring and Fall for two years and the trees are doing great.
