Roundup can be usless before you even get to spray it if your PH of the
mixture is very high. It should be 5.5 Ph.
If you would like a list of the different sprays and the proper PH. Please
contact me I have it. We had to remove the manufacturer's name to put it in
the Michigan Nutgrowers.

My understanding is tha Roundup biodegrades rapidly after it is mixed with
water.
If you leave some in the sprayer all mixed for a few days you will find it
does not work anymore.
A normal spraying of 2-4-D washes into the soil and will migrate within the
soil over a long period of time, but tests have shown that it moves very
slowly and in a normal soil (not sand) it will be many years before any
shows up in the water table.

spray? Does the 2,4-D wash into streams or water table? I remember when
Roundup first came up it was supposed to "bind to the soil particles", this
doesn't make me overly comfortable, but perhaps it prevents it from washing
into streams or the water table.

killer, it has been popular for corn.
Whlie our FDA does not monitor it, the European medical community has been
using oral imunization methods for years now.
