Nan, I found this so far. It's a PDF from https://www.ctahr.hawaii.edu/oc/freepubs/pdf/PD-35.pdf

Mechanism by which marigold suppresses

nematode pests

While marigolds (Tagetes species) are typically grown

for ornamental purposes as bedding plants, studies have

found that they can be highly toxic to plant-parasitic

nematodes and are capable of suppressing a wide range

(up to 14 genera) of nematode pests. The nematicidal

potential varies with the marigold species and cultivar.

I haven't found a variety called 'Nemacidal' yet. I think it's more referring to a group of certain marigolds.
