Glyphosate inhibition of ferric reductase activity in iron deficient sunflower roots [PDF]

open access: yes, 2007
Iron (Fe) deficiency is increasingly being observed in cropping systems with frequent glyphosate applications. A likely reason for this is that glyphosate interferes with root uptake of Fe by inhibiting ferric reductase in roots required for Fe ...
