Paul,
If you mean did it suppress the growth of the nursery plant in the pots -
the answer is no. Here is a quote from an article in the March 2001 issue
of "Digger", the magazine of the Oregon Association of Nurserymen:
"Within seven days of top dressing infested pots, Marchantia began to die,
and within two weeks the weed was dead, leaving almost no trace of itself.
Meadowfoam's (Limnanthes alba) effectiveness is due to multiple bioactive
compounds that inhibit growth, making it more difficult for the liverwort to
adapt."
And there was more. (During trials) "We started noticing there was a growth
effect on average, plants treated with meadowfoam saw 25 percent more growth
than the controls. For example, one nursery trial found that plants that
typically take two years to produce reached saleable size six months early.
This was done by simply incorporating a small amount of the meadowfoam
seedmeal into a soil mix that has taken years to perfect for optimum
fertility".
In re-reading this article and more about meadowfoam on the OSU web site, I
see that it is being marketed on a trial basis by the Natural Plant Products
Cooperative as 2 formulations of fertilizers
1) AlbaGro 4/4/4 (NPK) and
2) AlbaGro 4/0/4/4s (NPKS) for acid loving plants.
3)
I'll be heading down the valley to the Ag co-op that is selling it in a few
days. I'll let you know if it works for me later in the year.

Did it also suppress plant growth in the pots? I do not have a lot of
information covering liverworts in my library. Since they do produce both
sexually and asexually control of their spread once infected seems do be
difficult in a wet environment.
