What is a good ground sterilizer that will last at least 2 years?
==Paramathal== "Paramathal" (pa-ram-ma-thall): It should last
about 3 years, but it migrates in the soil. In other words, it
travels. So if you use it, it can travel as far as 8' past your
target area. Also it will destroy all the rubber gaskets in the
equipment you use to put it on with. One other thing, someone who
uses this stuff must be licensed. ==Gasoline== Something easier to
get, but only lasts a year is gasoline and you don't need a license
to apply it... just common sense. ==Bromacil== Gasoline is
dangerous to apply. Better to use Banish Total Ground Sterilizer
containing Bromacil. Very powerful and long lasting. The link is
