I mix concentrated Ortho Weed B Gon (Plus Grabgrass Control) with

I suppose that it works, but I don't exactly see the spray "wetting"
the
leaves and stems of the stuff I'm spraying. Looks more like most of
it
beads up on the leaves and runs off.

I'm thinking that this stuff would be more effective if it "stuck" to
the leaves, and I think that's only going to happen if the surface
tension is reduced, possibly by pre-spraying the weeds with soapy
water,
or alternatively maybe adding soap in with the weed killer and water.

Does anyone have a clue regarding if the effectiveness of
water-soluble
weed killer is increased if a surface-tension reducing agent is used?

And just for clarity, Ortho Weed B Gon contains:

2,4-D (Dimethylamine salt)
Quinclorac
Dicamba (dimethlamine salt)




No way would I ever toxify my yard, I found that after a good rain it's
pretty easy to pull out the weeds roots and all.

Good luck doing that along a half mile of fence.
