Is this black spot or did I burn my roses?

Hello everyone,
It has been raining a lot here in north Alabama this early spring. My baby roses were getting beautiful foliage, and I decided to spray with Bayer’s advanced disease control last weekend as a preventive measure. Last year I used that product and except for some minor black areas on lower leaves my plants looked ok. I work and live a couple of hours away from my garden during the weekdays so today I arrived to see all my little roses covered in bad looking light colored spots with darker rims. I don’t understand how it happened right after spraying. Is this really black spot? Or did my spaying somehow burned them? Thank you so much for any info.

Several of my roses are defoliated from black spot
Comments (25)Having been born and raised in California, earthquakes don't bother me much. A few years back we had a family reunion in Kansas and I thought it was pretty funny that the relatives from Kansas were all telling us how scary the earthquakes must be while all us Californians were worrying about tornadoes. I'd take earthquakes, fires and landslides over tornadoes or hurricanes any day! I think that most people are more comfortable with the natural disasters that they grew up with, but everybody has something to worry about, right? California will get a massive tsunami eventually, it's just a matter of time. In fact, there is a chunk of Hawaii that will fall into the ocean someday and trigger a mega tsunami that will threaten the entire West Coast. There is a similar situation with one of the Canary Islands that will someday threaten the entire East Coast. I think you would be hard pressed to find a place anywhere that doesn't have some sort of threat looming over it. That's why it's important to not worry about that sort of thing, just take every day as it comes and enjoy the beauty (and roses) that life brings your way....See MoreI burned some of my roses
Comments (6)What you did is called "Spray Overload." If I had been in your shoes, I would have sprayed the Avid, because spider mites can defoliate a rose bush faster then a speeding bullet. Another thing, if you spray with Avid, you have to spray again in a couple days to get the newly hatched mites, because Avid is a contact spray. When I spray, I never mix the chemicals together. I know a lot of growers do, but I have found that singly is better. I also, never use Bayer, because I find that there are no silver bullets out there, no "One size fits all," and because around here Bayer doesn't do well at all. I don't know why, but it just doesn't. If the BS were to build up while you were away, there is a way to get rid of it once you are back. If you want to know how, go to "My Page," and email me to find out. I have been in this game for 30 years and know what I am talking about.

Comments (4)K2laser, I live in South Carolina and we have the hot humid summers, not as long as you, but we sure get hot during the summer and the humidity is so thick you can hardly breathe. There are some hybrid teas that are very black spot resistant, I would research that onine and ask in this forum for some names of some of them. You really can't ever get rid of black spot on a rose. You can spray all kinds of expensive sprays dilligently on the rose bush and canes, constantly keep the rose bush real clean, don't let the infected leaves blow into other roses, and they will always have it. I bought for the first time this spring a knock out rose, double red. It is the only rose in my garden that doesn't have black spot. It is absolutley gorgeous! Clean foliage, and grows fast. When I get tired of all the nonsense for my hybrid tea rose trees and black spot, I will buy another knock out. All you ahve to do is water them, don't even dead head them. Low maintance, it is a beautiful thing....See MoreIs this black spot? Spreading to all my roses
Comments (5)I did not see any organic fungicides on the Witherspoon website. What does the label say is in your fungicide? I had excellent experience using ordinary corn meal under my roses. I had neglected the roses for other projects. By the time I got to this they had both black spot and powdery mildew as well as aphids. I cut off all the leaves with black spot, scattered a heaping handful of corn meal under each plant, and then dropped some compost. Then every month I repeated with only the corn meal. The second year I repeated the compost and monthly apps of corn meal. The corn meal is both an anti fungus agent and also an organic fertilizer. Corn meal works by attracting a predatory fungus that attacks the disease fungus. And I don't know if your experience will be like mine, but my aphids disappeared immediately with the corn meal and compost. That first app was in 2002 and for the past 15 years they have had no disease or aphids. I know how ridiculous this sounds, but I swear I have not used any other products on them....See More

Thank you vaporvac, mad_gallica, and Moses.Sorry for the delayed post. I have been in the yard spraying and obsessing over every plant
Varporvac I am attaching a picture of the product I used.
mad_gallica the temperatures have been fluctuating from the 60s during the day to the 30s and 40s at night. Everything is up tho and some even have buds.
Moses your description matches what I have. I never got that pest last year. I might have made the spray solution a little on the strong side so I worried about that too. I went outside and sprayed again today. I hope it goes away, I was really looking forward to my cute roses this year.
