black spot remover

[j.flett]

found a tonic in an american book that recomends,15 tomato leaves 2 small onions chopped and soaked in 1/4 cup of rubbing alcohol overnight and then painted on both sides of the infected leave,to remove black spot on roses.untried as yet by me ,but one i shall try when i get tomato leaves again,

[Snadger]

I always thought that once the spots appeared on the leaves the fungus was actually into the tissue? If they were just on the surface a soap solution would take them off surely!
I think the fungisides sprayed on them only controls, not cures, the fungus and stops it spreading it's spores. If what you have read works it must have fungisidal properties and do the same thing!

What the heck is rubbing alchohol? Is that the stuff used as a wound cleaner before bandaging?

That sounds as though its definitely worth a try. Had black spot on my roses this year, and the spray I bought to treat it didn't have much of an effect. I'll try pretty much anything to prevent bald rose bushes next year.

Snadger, I think that 'rubbing alcohol' is another name for surgical spirit

If anyone has an old tin of ***** Fluid there is a treatment for Black spot on the side. Another thought is that an infusion of Horsetail is supposed to act as a fungacide. Does anyone know anything about this? I would be very interested

[j.flett]

horsetail as far as i know is good for keeping slugs of of your plants due to the fine silica in thier leaves, acts as crushed eggshells, but ill try it as a fungiced as well in springtime

Rhubarb leaves put in the planting hole for brassicas are supposed to help against clubroot which is a soil borne fungus. Also used as a general garden insecticide by some after being boiled up! Naughty, naughty tho as EEC rules say we can't do it now!

Why have they rules that Snadger? What's wrong with rhubarb leaves... surely they're okay as they're natural?

So is digitalis, but you wouldn't put it in your coffee!

Basically it's because it is untested Shortie. The reason that ***** Fluid & Armillartox was taken off the shelf for use in the garden (clubroot control, steralising soil etc) was because it was going to take £1000's a year to comply with the testing to satisfy the eurotwats er sorry burocrats. It is also the same reason why seeds disappear from sale - they don't get maintained on the approved list so you can't sell em. Hence Peer Gynt Brussels have virtually gone & the seed companies can flog you an expensive alternative - sorry do I sound cynical

Doesn't matter that rhubarb is natural Shortie, it's like lots of herbal remedies also which you can no longer buy because of the same rules-if it hasn't been tested & approved for that particular use you can't officially use it!
