It appears too be chemical damage thou I would not know what type. This is the closest I've found so far. Not really a match, going too try and attach a photo so that I can see both photos together.

That is a photo of glyphosate damage on a tomato plant.

Never seen anything like that... very interesting...

Could it be fertiliser burn?

I am not sure. I use miracle grow which i only put on the soil not on leaves. And I normally use it less strength than what it ask for. I also use fungicide. The last fungicide I used was Honor Guard. I mixed it with Conserve due to chilli thrips. I have been doing this since the summer. I very much doubt that I used too much because I am very careful with measuring. I was always taught the old adage to measure twice cut once. Also I have 18 roses in this bed and I used the same tank to spray all the roses. Only two seem to have this problem. I wasn't sure if it is lacking a micro nutrient or if the soil could be too nigh in acid or to low etc. etc.

Thanks for your comments and if you have any other thoughts please help. Thanks so much. And thanks Marybeth for posting my pictures.

What about a root problem inhibiting the uptake of nutrients?

Patty what kind of root problem.

This past summer I dug out a 4 feet deep by 5 ft wide and 60ft long. This had been nothing but sugar sand. I replaced it with aged "decomposed" horse manure. Then in each rose hole I mixed the decomposed manure with miracle grow garden soil. The roses looked healthy until this last growth spurt.

Well, now that you mentioned the manure several possibilities come to mind. The first is hormonal herbicide damage. While it's not typical of what you would see. I did find some that where close. Are most of your damaged leaves cupped like and is that tissue collapse on that one leaf that I see. One photo closely resembling your damage was cause by ALS inhibitors. The damage was seen in grape vines in Kansas. It does not tend to damage existing leaves but will affect new growth.

Of course there is the possibility of root burn in the manure.

Could you cross post this to the Antique roses forum also? There are some very knowledgable people there who tend not to frequent this forum.
