Does it work on roses for powdery mildew and black spot?

I didn't use it on roses. I used it on tomatoes. On roses, I used Bayer 3-in-1 for roses which did indeed work.

says to begin treatment when new spring growth emerges and repeat every 7 to 10 days for as long as needed to control disease. Also says tho it may cause some copper toxicity on some roses. This toxicity appears as purple spots. Treatment is for blackspot and powdery mildew

I bought it for pet order. I did not feel it worked that well. I did not try it on mildew or sour laundry. Instead of buying something this expensive for mildew or sour laundry, buy clorax bleach and spray on the mildew if it is on the walls. Great for laundry.

Don't know. I use it on zinnias after the first 2 sets of leaves come up. Helps with powdery mildew.

I bought this product to use on my basil, which had downy mildew, and my houseplant, which have an assortment of bugs and mold....I found it worked well on my lemon tree, which had mold, too, but you will need to treat it routinely. See direction on product label.

Yes. it works for most things that bother my bonsai. What I like about it is it doesn't hurt the insecticide sensitive plants like desert rose. You may have to use it several times.

Not sure about mildew. It does take most stains out. For difficult stains, I spray it on, rub in a little, then let it soak in cold water for a couple of days, then wash with next load of wash. 98% of the time stains are gone.

I have not tried it on mildew, but my guess would be yes.. as it works great on places where pets have marked ;)

Just remember that when applying this to your roses you will kill any honey bees or other beneficial pollinators. This german made product is not available in germany or europe because of its toxicity. I would look at organic alternative. Good luck to you

I don't recommend using it on flowers. If I were spraying around a foundation where there are plants I would be very careful not to get it on the plants.

Have used this steamer to clean mineral buildup around faucets and shower heads. Would bet it would work on water spots. I like to spray areas to clean with Scrubbing Bubbles or Dawn DW liquid before I use steamer. Hope this helps you.

It works well on Powdery Mildew on most plants in my yard including squash, cucumbers, roses, and herbs. However it is necessary to reapply regularly. There's little doubt that mildew spores can travel on the wind and also remain alive for years in one's own compost pile, containers, and soil. As such, it is difficult for me to completely get rid of the mildew without routine applications.

Hi Frank.....It took the stale smell of cigarette smoke out of a car, so possibly it will work on mildew too. IF whatever has caused it no longer is an issue.Have found it very effective on all kinds of disagreeable odors.

I've used it in the morning on my roses and apple espalier when they seem least stressed from heat. The apple espalier had flowered and the new green leaves were showing powdery mildew. It seems to have eliminated the disease.

Once black spot occurs on the leaves the plant is already infected for the season. Very difficult to do anything about it. Best advise is to use a systemic fungicide at the start of the season as well as the fungicide powders on early growth and remove all dead canes and any debris around the rose bush at the start of the season. Also do not use unclean pruners between other rose bushes during the season. Wash with the pruners with alcohol before each and every pruning episode. Essentially once it starts its very hard to stop it. Usually it does not effect flowering though. It just ends up defoliating the plant and the fungus progresses.

I have used action and it did help some but did not eliminate the dark spots. I think it will work if you use it sooner than later.
