Hello,
My understanding is that a sprout test will indicate if a medium is good,
bad or ugly. Herbicide residues will be indicated by fewer seeds sprouting
in the medium.

This is an excellent test to see if the level of persistent herbicides
is high enough to kill your plants.

This test does very little to tell you if there is a level of
persistent herbicides to stunt the growth of your plants or make them
more susceptible to getting sick.
