Hi Bob,

Trust me, I tried the weed killer.

Every year I buy this 2.5 gallon concentrated (41%) glyphosate (which is
a huge amount considering you dilute it 2 ounces to 5 gallons of water):

Notice those gloves in that picture are the ones I used on Sunday and
they're already starting to show the black urushiol lacquer, which only
reveals itself a day later (or after washing), presumably as it oxidizes.

The problem is that you need a helicopter to get the weed killer on the
leaves. Sure, I can spray the entire front by the curb, but how do I get
the spray 10 or 20 feet deep and down the very steep hillside?

You might try a sprayer intended for fruit trees; long snorkel.



here in phx, they spray olive trees to prevent flowering. they use what
looks like truck mounted pressure sprayers with a very long hose and
wand so they can reach the top of the trees some 20-40' up.

Perzactly. I've seen them used on apple trees, too.
