weak dilution of Jeyes fluid

has anyone any thoughts of using a weak dilution of Jeyes fluid as a winter wash on roses trees. This is a spray to kill the black spot spores on and around the trees. Any thoughts, please feel free to air them. V

 

I used the old style jayes fluid as a winter wash on my grape vines last winter and they grew really well last summer.
I don't think that the modern stuff is half as effective but I don't think it would hurt either.
The modern stuff appears to be just a disinfectant similar to any household disinfectant that you can buy.
I think with roses it would be best after a prune and a complete tidy up of the area underneath.

 

I make up a mix of 5 ml of Neem oil and 2 ml of washing-up liquid per litre of water and spray that as a winter wash.

 

OH yeah, that well know fungal pest of roses,.........badgers.

 

I have found that Jeyes fluid keeps badgers away....but foxes don't mind it at all - unfortunately.

 

Thank you all for the advice and ways to do it. My Jeyes fluid is an old bottle found in the shed. What dilution do you think @pete that I should have the mixture. V

 

I just add a dribble to the sprayer, its not very precise I'm afraid.
Is it black or green?

 

@pete it’s blackish, but I shall get some new stuff as there isn’t a lot of the other. V

 

Sounds like the old stuff.

 

I have used the 'old stuff' for many years; and reluctantly bought the 'new' as the only available option .(Its not helpful for the label upon it to declare "the original formula" when its clearly not.)
However, recently diluted and applied to moss on tarmac on the northern side of the house and much to my surprise, it has turned it brown, as if it has killed it. No claim by manufacturer for any such use, doubt its "approved"
In light of this, I am to 'winter wash ' an apple tree to hopefully "kill " lichen and grey aphis. Greenhouse glass and pots will also be treated, it can only be wasted once! Do any of you have experience to relate regarding the use of this ersatz Jeyes?
