After treating the said roses with iron chelate the other day, I was doing a ph check on all roses today. One thing that stood out was while all roses were in a range of 6.5-7.0, the roses with the iron deficiencies had a ph of around 5.0.
Would these readings be a direct result of applying the iron chelate... any ideas please

Fe3+ is insoluble in neutral and high pH, making iron unavailable to plants in alkaline and in calcareous soils. Furthermore, in these types of soil, iron readily combines with phosphates, carbonates, calcium, magnesium and hydroxide ions

After applying iron chelate as per packet instructions I have just noticed that the said planta leaves are getting lots of black blotches over them and they are looking a little sickly. Could this be burning of the leaves???

I been receiving emails from Richgros Agronomist regarding trace elements. He feels that even though I'm using there basic bulk mix, buy adding cow manure, seamungus etc the should be enough elements in the mix without adding more. Hmm, I've got to think about that one

Paul, John and myself are thinking alike. I have never used it "but" I would assume it is not for foliar spraying, it can be foliar sprayed I think it would have to be done in the cool of the day.

My first guess is "burn", what else has been in the sprayer Paul ?

Thanks roseman, I always do a thorough rinse of the sprayer and the hoses after each use, however having said that, the last thing it was used for was Triforine, prior to that it was Lime Sulphur at pruning time..... Ta

Looks like iron chlorosis, either too high ph (alkaline) or something else preventing iron uptake.

I was down at Dawsons today buying a Neptune Rose, while there I was talking to the nursery man who told me he was a qualified agriculturlist/geologist one of the two lol, about the burning issues after applying Iron Chelate. A couple of things he said were... I would have used Iron sulphate instead and he definitely would not spray the leaves, because it would cause burning. Well that's great, that's not what the package says.
He also recons there would be enough elements in something like Sudden Impact, that over time would correct any iron deficiencies.  I think I need to email Manutec and ask for a please explain.

Paul, if you do please ask for the Tech rep to respond, not the girl/boy on the end of the email, will you keep us upto date please on what transpires.
Did you ask why he would use the sulphate instead if the chelates

Thanks roseman, he did mention why he would have used iron sulphate insread. Something about citrus plants, however he did conceed you can use the chelate on roses. Not sure what he was getting at, he also mentioned that what ever the label reccommened, he would start by using half of that. The main reason I went there was to take back my oranges and lemons rose that refuses to flower. Dawsons had told me previously that they deleted it from their range because of that reason, and suggest even though it wouldn' bloom it would be a nice plant to keep, Umm not. Anyways after I explained the facts of life it was exchanged for another rose with all smiles.
