Shag-bark hickory (member of the Walnut family) - will it cause allopathic toxicity due to the amount of juglone released by its roots to fruit-crop trees like Prunus (cherry, apricot, etc.) and other plants like che (Cudrania)?

I know that shag-bark hickory produces far less juglone then black walnut.
