I'm experimenting with it in my garden right now. Definitely had a fusarium issue this year (tomatoes in the same location for 3 years running). I have hairy vetch in now as a cover crop in that bed and will plant tomatoes again next year to see how it goes.

This info came from a gardener Youtuber, but it appears backed up from a google search. It appears the experiments were done with watermelons, but I would assume the results would be the same with other crops.
