Azoxystrobin is a broad-spectrum, systemic
and soil-applied fungicide used for crop protection on more
than 80 different crops. Azoxystrobin use has induced
water pollution and ecotoxicological effects upon aquatic
organisms, as well as heath issues. Such issues may be
solved by phytoremediation. Here, we tested
Plantago major
L.,
Helianthus annus
L. and
Glycine max
L. to clean
soils under laboratory conditions. Results show that the
accumulation efficiency of azoxystrobin and azoxystrobin
acid in roots was higher than those of leaves.
G. max roots
were an efficient accumulator of azoxystrobin (25.32 mg/
kg), followed by
P. major roots (20.62 mg/kg) and
H.
annus roots (18.29 mg/kg), within 10 days, respectively. In
the leaves, azoxystrobin significantly translocated into the
P. major leaves and reached the maximum after 10 days of
exposure (15.03 mg/kg), followed by
H. annus leaves
(9.8 mg/kg), while it reached the maximum after 3 days of
exposure (3.12 mg/kg) in
G. max leaves. Azoxystrobin
acid significantly accumulated in
P. major roots more than
the
G. max and
H. annus roots. In the leaves, azoxystrobin
acid significantly accumulated in
G. max more than
P.
major and
H. annus. The presence of
P. major with Tween
80 had effects on azoxystrobin desorption from soil, plant
uptake metabolism and translocation more than
P. major
alone.
