Is that for reducing the amount of life a tree suports?

Looks like Bob's I.V. tea flask.

is it for wine making ......

haha brilliant and would work too.. its a treatment for bleeding canker in horsechestnuts, still being trialled but good results so far, would expect the wet areas to dry out and hopefully begin healing over. going to keep a close eye on these now. pics showing coupling removal and plugging.

Hi Ed,

 

is this the Allacin/Conquer treatment that JCA are trialing?

Intriguing! Could you explain a bit more about the science behind this?

[Amelanchier]

Simply put - the theory is that the infusion of Allicin (that is to say the drilling of holes in the tree and the pumping under pressure inot the vascular system) will kill the pathogens resonsible for whatever disorder/disease you wish to cure.

 

A UK consultancy company called JCA have pioneered its use in the UK in association with this company - Allicin treecare They claim to have documented proof from a Dutch research lab ("...internationally highly respected organisation TNO, Organisation for Applied Scientific Research, The Netherlands") that their stabilised compound - NOPEX BK™ cures Horse Chestnut Bleeding Canker, Leaf Miner and kills "fungal mycelia".

 

However, if you scratch the surface of these "test" reports you find that evidence does not support the claims as fully as presented (you'll find the links to these documents on the homepage above).

 

• The Bleeding Canker test results show that above an indeterminate threshold (125 -250ppm) Allicin inactivated or inhibited P. syringae (no reference to the exact pathovar) for the duration of the test (8 days). Below that threshold, no effect was found.
   
  
• The test against "fungal mycelium" was undertaken against Aspergillus spp. and showed a inhibition of growth above certain thresholds (25 ppm).
  

 

And aside from non-independent anecdotal evidence, that is the basis for the treatment. Two short indicative experiments and straight to the market.

 

No information is provided to answer questions about how this is scaled up out of the petri dish or how the concentration is calculated and maintained. No information provided about what happens to P. syringae p.v. aesculi when the treatment ends. No information regarding long term managment or impact on tree health. No information about the effectiveness of the treatment of actual tree fungi good or bad! No information generally really.

 

As you might guess. I'm sceptical.

i passed a tree the other day that was oozing with bleeding canker last year and had signs of leaf minor, all the other ones in the woodland that were the same have died yet this one is flurishing, it looks great. i shall return and take a pic of it and try and find last years picks for comparison.
