I'm looking for an alternative to arborfos which has tripled in price for the liquid and gone thru the roof for the mauget autoinject. my london plane has been limping along for the last decade and shown improvements when treated a couple years back with the arborfos. currently it's tough to obtain the product and when you can the prices are excessive when compared to just a few years back. a 500ml bottle was $55 and reasonably priced for an anti fungal. any other options out there?
