Nonsense. In 30 years of observing them in my "wild" areas, I haven't
found this to be true.

Does anyone know the origin of this misinformation and why the books
keep repeating it?



Juglone does not prevent all plants from growing near the walnut tree,
but some plants are inhibited. Look up "walnut wilt" on Google for a
list of susceptible plants.

In wild areas, plants that are not susceptible to juglone will
predominate around your walnut trees. However, if you try to introduce
other varieties you may run into trouble.
