We have three mature horse chestnut trees on our village green and have

What is your opinion of this outfit?
Is this treatment scientifically founded or mere quackery?
(I am sceptical and it is very expensive per tree saved)

www.forestry.gov.uk and www.forestryresearch.gov.uk
domains are both dead in the water

RHS & National Forest both say no chemical control is available.
Who should we believe?

Anyone know of any diseased horse chestnut trees with bleeding canker
treated successfully with this in the UK and did it actually work?

Thanks for any additional information or contacts.

The only thing I can find related to allicin is the use of garlic juice
to treat red poultry mite:
