CLUB ROOT

Comment by Colin Robinson on September 20, 2012 at 22:20

Tony, you'll have the wrath of the EEC descending on you if you mention things like that. They're paranoid about anybody using anything for any purpose it wasn't designed for.

It's not a pleasant thought but I wonder if stale urine would do the same job as it contains ammonia which eventually breaks down.

Colin it would not raise the ph enough,Medwyn Williams sells Perlka as a treatment for club root.

Pesticide Safety Directorate actually - the EEC made the rules up but it is the PSD who enforce them; and in the UK they are enforced far far more than anywhere else.

But yes Colin, you are right. Off label usage of any pesticide needs approval - otherwise the fines involved can make Dick Turpin look like Little Red Riding Hood.

And just remember that if you sold your urine as a treatment it would require full approval - sort of takes the pxxx doesn't it? - considering that on more than one occasion 'organic produce' has been held at UK ports due to DDT contamination (as has been reported in The Grower magazine)

I think you may have the wrong idea about  perkla  its not a pesticide see below

You may wish to have a look at the Pesticide Safety Directorate website.

Anything sold as a pesticide (and that includes fungicides) requires approval.

If you marketed plain tap water as a treatment to kill ants it would require approval - honestly I have a letter to this effect from the PSD.

But you are quite correct, Perkla is not being sold as a pesticide as it makes no claim to cure plant diseases - which is why there are so many Bio Stimulants and similar on the market.

But recommending a product for use as a pesticide (for instance washing up liquid for aphids) would in theory make you fall foul of the current ridiculous regulations.

Jeyes Fluid used to do a little book 'Jeyes In The Garden' - but were made to withdraw it for this very reason.

I still have the jeyes booklet and the armilatox one.Several growers I know including myself have had very good results over the last 4 years with perkla,we still add a little lime in the planting holes but club root for us is a thing of the past.,it seems to have been effective in preventing parsnip canker also.the insructions on the bag its sold in say can be used as a potato fertilser but with a high ph I think potato scab would be a problem
