This product actually has glyphosate(roundup) in it, but at a much lower
rate
than in roundup. You may want to look at the dillution rates and see if
you
are using too much water in the mix. There are a few other factors to
consider
with glyphosate: If you are using dirty water(from a pond) or if your
sprayer
needs to be cleaned, this could make the treatments ineffective, since the
chemical bonds readily with soil particles. Another factor is the
weather. If
you have been having cool, cloudy days in your area, this can slow down
the
process since the plants arent growing as activley. The weeds you
mentioned
are all perennials, and sometimes they need 2 applications to really do
the
trick, especially for things like poison ivy. Glyphosate takes time to
work,
sometimes it can take a week or more(longer for perennials) before you see
dead
plants. I would wait and see, those three plants you mention are tough to
deal
with in the first place. You might try actual roundup instead because the
concentration is alot higher. There are a ton of other products
containing
glyphosate that are cheaper and work just as well, just read the label. I
hope
you have better luck in the future.

I was out a while ago on another errand and stopped by Home Depot and bought
some Roundup so my problem will probably be self-limiting. Live and learn, I
guess.

BTW, I'm one of those lazy sods who won't even bother to mix his own
chemicals (and who had an accident with a contaminated sprayer once) so I
just buy the gallon jugs with sprayer attached. I guess, given the cost
difference and the scale of the weed problems around here I really should
buy a couple of new pump sprayers and start mixing again (after I mark them
clearly!).

I buy the agricultural strength Roundup in the 2.5 gal containers and
mix according to directions. A few years back Roundup had a good
product that worked great, except you had to add a soapy product
(surfactant) to it to get it to stick to the leaves. I noticed if you
mixed the two and let it set for a few days before using it, it didn't
work near as well as a fresh batch. Well, Roundup, in it's great
wisdom, decided to market the product already mixed. Just as I
already knew, premixing just didn't work near as well. So after they
received tons of complaints, they remarketed it again in a stronger
solution to make up for the previous bad decision. Of course, now it
also cost about double the price to get the same action as before they
screwed with it.
Aahhh, these new and improved products!!
