my maple seems to have a fungal issue (new leaves deform) young growth barely survives. Could Lime sulphur treat this during dormancy?

Yes you can but I don’t think this will solve your problem. You need to spray with fungicide with active ingredient Chlorothaonil when the growth is still juvenile. Leaves which have hardened odd are not affected. Also I find this condition affects weakened trees so you might also need to allow it to grow out some to gain vigor.

Interesting. I was under the impression till now that lime sulphur is used only on conifers for highlighting deadwood. In that scenario, is it used in its concentrated form or diluted to a lesser extent than what you have used while spraying ? I have never used this product, so pardon my questions.
@TerryErasmusbonsai

You are correct that it’s used for preservation of dead wood in conifers which due to the concentration (undiluted) results in a white appearance. However it is used on all trees other than the ones I mentioned as a way to stop over wintering of pests and also fungus which may have built a resistance to fungicides.

Thank you, very informative. Treating my bonsai at this time. I was wondering what do you think about Apple spray and other fruit trees and should it be the same 1:20 solution? Also, when the trees are in the ground do you still need to cover the ground with wet towels or something similar? Besides that it looks bad - does Lime Sulfur damages the roots?
@TerryErasmusbonsai
Жыл бұрын
Thanks Alex for these interesting questions. Yes, I would use the same solution. No, no need to cover the ground if the trees are still being field grown as the effect will be hugely diluted when the tree is in a great soil mass. I’d not worry at all. Besides in agriculture they spray lime sulphur normally and they certainly won’t do any effort to cover the soil. Lime sulphur has the potential to kill soil borne bacteria etc however you are not doing a soil drench, rather you are spraying the tree so wetting the soil is incidental.

Hello Ja. I believe I said RECENTLY wired and then I explained why. A tree wired months ago would have healed and thus would not be at risk. So to answer your question, no. It would be fine to treat such trees.

Very educational video for me Terry! I have some questions: if i defoliate a japanese or a chinese maple in early summer can I use this method to kill all the bad things? I have some chinese maples that are already infected with fungus because the leaves are deform and then die. The shoots become black. I tried a lot of things and being honest i wil throw away the trees, do you have any advice?

I know how you feel. Judging from other comments made here, it seems like this is becoming an increasingly common problem. I know the issue as anthracnose. I do not know whether you can use lime sulphur during the season. Theoretically it should be fine. What I have done to help control this Problem is to spray with active ingredient Chlorothaonil just as new buds are pushing. So you can defoliate and then spray. Keep spraying with 5-7 day intervals until leaves have hardened off. The fungus seems to be a problem only on tender leaves but presents no problems with mature leaves. You could also then start introducing a good broad spectrum systemic fungicide.

Thanks for your comment. I am not sure. I guess you could use Lime sulphur on Portulacaria. I don’t think it would create any problems. You might also try something like neemoil or something with a pyrethoid in it.
