I'm growing some apple seedlings to use as rootstocks; Hidden Rose and
JonaFree.
The Hidden Rose germinated 30 plants / 30 seeds! (100% germ) The Jonafree
about half that.
I used a few of the HR seedlings to do an empirical test; "Seedling
Phytotoxicity of Bonide Fungonil" (0.087%Chlorothalonil fungicide).
Not one seedling shows any ill effects after 48 hours from a mighty blast of
the stuff.
Then, I blasted an Evans Cherry seedling with it. After 24 hours, no apparent
damage.
Some fungicides are not quite as friendly to seedlings!
Take this info at face value. !!
