Bonide for Rain Rot

Reviewed in the United States on September 18, 2013

I have a horse who had rain rot on her hind leg and it started spreading to her other legs and up her back. It a skin fungus that is almost impossible to get rid of, which I learned after trying everything that swears to get rid of it. Then, I finally asked a racetrack trainer friend of mine and she told me about Bonide powder. She said its a well known secret at the track that daily rinses of the infected areas with a couple caps of Bonide mixed with water will stop the fungus in its tracks and kill it so the skin can heal.

Worked like magic! Every days for 2 weeks I would wash my mare with dandruff shampoo from CVS, scrub the scabs off the infected areas to get to the actual infection and then rinse her thoroughly, mix just enough Bonide with water to fill the bottom of a bucket about half an inch, and then sponge it on to the infected areas. Leave it on there and let it drip dry. It will look sudsy like soap, but tries clean. Within 2 weeks, maybe less, the infection was gone completely, her skin had healed and it hasn't come back. It's been about a month. I actually bought extra bottles of this just to keep at the barn. It didn't burn her, or hurt her in anyway and usually I had to scrub down to raw skin to get to the right areas.

The jury is out!

Reviewed in the United States on July 4, 2020

I’m not sure if it is working yet. I went to the expert at my nursery. I hv a diseased fig tree! I live in the south. She had no idea what it was! We hv had tons of rain this spring, so many plants are getting fungus. But, I had this problem last year with the tree. I used the Bonide Copper spray last year. But the disease came back. Not rust. So she examined under her microscope! It has this disease that in her 30 years in the business, never, ever saw on a fig tree! On other fruit trees and bushes, yes. But never on a fig tree. So she suggested to buy this product. I looked at directions for other fruit trees and winged it. I pulled a lot of the infected leaves off. Sprayed for the last few weeks every 7 days. Leaves still turning brown. She suggested to still keep spraying and spray on new growth and see what happens. So that’s what I’m doing. The little of new grow looked like it was not infected, but who knows if it will when those leaves start to grow. I’ll hv to see. I’m giving it one more shot. My luck I hv a disease that was never found on a fig tree!

I used it to treat Clivia seeds

Reviewed in the United States on April 29, 2013

Verified Purchase

I use this product to treat my Clivia seeds. It dramatically improves the rate of germination by preventing the seeds from turning into mush. It helps prevent the seeds from being eaten by some kind of mold. When I do not use this product, a lot of the seeds get mushy.

The plastic container contains a light yellow powder which you mix with water. You have to be careful and make sure the dust doesn't fly everywhere. A small amount of it will get in the air, but it doesn't seem to cause a problem for me. Obviously, try not to breathe it into your lungs. If you want, you may wear an air mask.

Here are directions which include information from other websites for growing Clivia seeds. This is what you do with your Bonide Captan solution.

1. Use the solution to soak the Clivia seeds overnight. If the seeds are older, soak longer. If fresh, overnight soaking is fine. I also sometimes put in soluble seaweed as a light and natural fertilizer with the Bonide Captan solution.
2. Treat the soil with the Bonide Captan solution.
3. Clivia seeds have a tiny dark spot. Plant with the dark spot facing up. Plant about half the seed and leave the other half exposed to the air and bright light. I noticed that seeds exposed to light germinate, while the seeds which I buried more deeply with no light may not germinate so you may even expose more of the seed to the air and light.
4. Cover the seeds with plastic or other cover to keep the seeds moist.
5. Every so often, check your seeds and spray or water the seeds with the Bonide Captan solution to keep the seeds moist.
6. Keep the seeds warm.
7. I also water occasionally with a strong solution of soluble seaweed. Pour a little bit of this fertilizer over each seed. For example, once, when three of the four seeds had leaf growth and the fourth one did not, I poured the soluble seaweed on the fourth one and I saw leaf growth on that seed. It doesn't always work, but it does seem to help.

The most important thing is to get fresh seeds which tend to be large and white and firm. They germinate fast. Older seeds are wrinkled and more shriveled looking and may not germinate.

This product has worked well on our roses to keep down the mildew on the plants leaves. I like that it is a powder and will keep for a long time.

Great for peonies and strawberries!

Moved into a house.. every year this ugly as sin plant would pop up in a shallow bed by the front of the house and the whole thing would quickly turn black- all the buds couldn't bloom and were small and crusty. The leaves were splotchy with dry crusty black curly bits that’d eventually consume the whole plant. After a few years of this (and almost digging the darn thing up once) I decided to find out what the plant was and why it was so ugly...Thanks to google, found out I'm an idiot- it's a poor really old peony! Found out it's prone to this type of soil fungus that makes it look horrible! The next spring, I bought Captan and when the lil buds started coming up from the ground, I mixed up a solution in a sprayer and sprayed them good- they were maybe 4-6inches out of the ground then. I was suppose to follow up and do it several more times but I ended up hurting my hand and all-things-gardening-related got put on hold... but it didn't
matter at all! With just that one little fungicide treatment, we were treated to a beautiful lush green plant with what my dad called “double blooms”. They are a really full flower, pure white and super pretty!!! Thank you captan! Just gotta remember to use one of those plant supports this time so they don’t fall over with the first rain. Going to use it on my poor rose bush that got really bad black spot last year, due to it being my very first rose bush ever lol. Also going to use it on my strawberries again- it cured this weird fungus that was causing the berries to rot before they were even ripe last year. And on my blueberries as I also have had fungal issues there too.
I just wish I knew if there was an “all purpose” ratio to mix up that’d suit my needs, as each item/plant to spray has a different suggested ratio and I'd like to mix up all one batch for my little garden :)

Captan works on the black rot fungal disease (among others)

Reviewed in the United States on January 18, 2014

Verified Purchase

I effectively use Bonide Captan I bought from Amazon for black rot in grapes (among other things) and have for years. I prune off diseased canes every year and burn or dispose of them. Taking great care to pick off mummified berries is critical. I don't have many diseased canes or mummified berries now but I once had a huge problem. It depends on how much it rains because the disease spreads during wet weather. By pruning the grape plants to a more open top I can effectively reach the spray areas better and they dry out quicker. Since rain spreads fungal disease such as black rot I ensure I spray prior to rain but never directly after rain. The new growth from last year is partially left on during pruning because it produces my grapes. I make sure and spray my first application when the grapes first start to bud out (pre bloom). Spray mine every 7-10 days during the critical times. Black rot is easy to identify by the round brown spots on leaves, mummified fruit, lesions on vines and of course the fruit is beautiful until it starts to ripen and then rots instead.I'm not advising you to follow the methods I use but rather do your own research and maybe my review and Captan will help you get some grapes.

I use this to store my tropical water lily tubers. I wet some polyester batting with a solution of this and distilled water and then place the tubers in ziploc bags. Kept in a dark room temperature space they stay alive and dormant, ready for the next year. I have a low rot rate with this method. This has done a good job keeping the fungi at bay.

This seemed to work well to keep the fungus off my fruit trees. It did NOT work well with my peach tree as for the second year in a row, it caught the brown rot even after spraying it routinely since before spring. I do plan to continue using it as it helped with the fungus on other trees.
