Fungicide for canker

RedQueenie · July 2023

Hello, I believe some of my roses have canker. From the articles I've read, they have said to cut back below the canker dunking the shears between pruning with one part bleach and 4 parts water and spray with a good fungicide. Please could someone tell me the name of one I can use in the UK or if they aren't available anymore does anyone have any other advice as to what to do?

Are you trying hard enough? Have you heard of Google? Try googling RHS fungicides.

Trying hard enough?? I wasn't aware that I had to try hard to find a solution on Google before asking on a website that in the past has been incredibly knowledgeable, helpful and kind.

Try a garden centre then. You'll be getting lazy.

I apologise if you have some mobility problems that I was unaware of, if so use Amazon.

Take no notice of him @RedQueenie … for some reason Bédé has made it his mission in life to be ill-mannered and objectionable, especially to new-ish forum members.

Why? I can’t imagine … surely he can’t get out of the wrong side of the bed every morning … it’s like having a sulky teenager on the forum .., maybe he’s entering a second childhood 😉 Who can say?

As I’m very concerned about the increasing reports of developing resistance to fungicides causing health problems to humans as well as animals and plants (as with resistance to antibiotics) I will not use fungicides in my garden, so I can’t answer your question … but you are totally free to ask it and shouldn’t have to run a gauntlet of bullying. I hope you won’t let it put you off using this forum 😊

You are but one person on this forum, and from the communication I've had from you so far not very pleasant.

I've posted my question on the 'problem-solving page'. If you have nothing helpful to say to people that are new to gardening and seeking help then maybe you shouldn't check or reply to any questions that should arise here.

Thank you so much Dovefromabove for your kind words. They do seem to be quite cantankerous and not able to talk much sense. I will ignore them from now on.

Thank you also for your reply about fungicides. Is there something else you use or would do to solve the problem? I tried last year to keep cutting it away and it has helped a little should I just continue down that route?

You’re very welcome 😊

It’s not a problem I’ve had to face, but there are some very knowledgeable rose people on the forum, @Marlorena and @Nollie spring to mind. I’ve given them a nudge for you. Hope they can help. 😊

You can also report anyone who is rude, to you or to anyone else, @RedQueenie. If you click the flag option [below the posting window] you get a choice of spam or report. Just choose report and follow the instructions

Apart from that, @Dovefromabove's nudge to the knowledgeable rose growers here on the forum will hopefully yield an answer for you

Glad to see the adults have entered the forum!

Thank you everyone for your backup and kind words and thank you again Dovefromabove for nudging the rose experts.

Are you quite sure you have canker? it's only serious for a rose if the canker has spread more than half way around the cane, then it needs to be cut out.. if it's less than that, and has flower buds, I would let it bloom and remove the cane later...

If the canker is right at the base of a cane, then it should be cut out.. otherwise cut below to a healthy part... wipe the secateurs with disinfectant, although I'll admit I never bother, and you shouldn't need to use a fungicide... if the rose is so badly affected down to the base then it's time to be rid of the rose I'm afraid..

If you are able to take photos of your roses and post them here, we can take a look at them and see better what's going on..
