Seedling or shoot damage caused by root
absorption of paraquat is rare in most soils but
incidents of root absorption and translocation to
seedling shoots have been reported (DiTomaso et al.
1993). Damanakis et al. (1970a) found that
paraquat, even when applied to muck soils, could
inhibit seedling growth. They reported shoot
inhibition as a secondary effect caused by root
inhibition because no toxic symptoms were observed
on the shoot (Damanakis et al. 1970b).
