If you look into the MO(Mode of Operation)in regards to Pre-M, you would find that it gets drank in
by the root of the germinating seed
right along with everything else in the soil moisture, including NPK...
So one of the first things this new little seedling ingests is a growth inhibitor
... germinating seeds are vulnerable to many things,,, that they must overcome in order to survive...
Therefore it is easy to kill them with a root inhibitor
,,, and that is how it works...
if there are gaps in your application of pre-m and a seed germinates in that area, it will not die, becuz there is no herbicide in that spot... this idea of complete coverage
is what advertizers/salesmen have coigned as The BARRIER
... so beware of allthe mythology that has built up around the pre-m...
And DON'T take my word for it, or anybody else'd word for it... research
'method/mode of Operation', with pre-emergents... other opinions about other 'cides are likely valid, but this one, you'd bettersearch out yourself...
