Tar wash

It's officially banned as soil steriliser, pesticide, and winter wash, BUT it's still available as patio cleaner.  :o  I don't really understand why it's been banned (except that the companies that produce it can't afford the six million £ needed for the tests to prove it's harmless to humans), as the only really nasty stuff associated with it is naphthalene, which is not a component of the wash, and anyway needs to be inhaled chronically to have serious long term effects. Plus if it's still ok for cleaning . . .

Anyway, to answer your question there are some newer washes around but I know nothing about them and suspect that in a few years time they will be found out to be not as safe as they are supposed to be. (Yes, I'm a cynic.) I prefer the devil I know which is Jeyes fluid and Armillatox. I looked pretty hard to find out why it was banned and drew a blank except for the association with napthalene/creosote. Nicotine and pyrethrum and some others however, it's easy to see why they are banned.

It's traditionally used in winter, and I think it has more to do with foliage damage than fruit. I think Armillatox website has more info. I'm pretty sure the dilution ratio is different from when you use it on patios too.

Edit: It's only 3 million £ my bad  
It's now called Armillatox Soap Based Outdoor Cleaner
"Use as a winter wash to revitalise your cankerous fruit trees. Spray in November at a dilution of 50:1"

You're welcome
