Here is the published trials for Sporekill with Trichoderma harzianum and Verticillium Fungicola (click on link)
The findings were in summary:
It is very clear from these results that Sporekill is very effective at halting germination of spores of the pathogens tested.
At concentrations at or above 0.5 %, Sporekill in these tests killed all pathogens we have tested so far.
When engulfed with Sporekill at concentrations at or above 0.5% the pathogens do not germinate.
