Ok, understood. Triclopyr is my first choice for killing vining vegetation. I have seen situations where glyphosate was repeatedly applied in an attempt to kill vegetation not susceptible and more collateral damage was caused.
Only other bit of advice I could give you is to watch your application rates. Both fluroxypyr and triclopyr will kill via root uptake. That normally happens when gross overdosages are applied. If the product says 1 qt per acre, that does not mean to apply 1 oz per gallon and 4 gallons of that mix per 1000 sq ft.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
