Our histopathological findings had pointed toward a phytotoxin as the possible cause of the disease (11).
Ground-level ozone is also a strong phytotoxin, causing significant platn damage.
The pathology does not support an infectious cause, but a toxic injury, possibly due to a phytotoxin, may be involved.
In vitro screening of rice germplasm for resistance to brown spot disease using phytotoxin.
The contention that the existence of an effective phytotoxin in the root and rhizosphere of a plant from a densely vegetated, multispecies wetland can be inconsequential to the success of this plant is, in our opinion, questionable.
found that unidentified phytotoxin substances of oak-leaf litter remained inhibitory for phytoplankton for more than 18 months in aerated water, suggesting an unknown complexity of phytotoxin effects.
It can contain phytotoxins that cause blistering of skin, so should be treated with caution, but it is not the same thing as Heracleum mantegazzianum (giant hogweed) which is the one with the toxic sap (and which might also likely be present in Cardiff ).
However, eutrophication is considered also as a major factor in determining reed decline, and the reed weakening by eutrophication is further forced by increased accumulation and decomposition of organic matter under anoxic conditions releasing fatal phytotoxins (Armstrong et al.
