Growth Regulators
Dicamba - - Group and MOA?
Group 4 - Growth Regulator
Aminopyralid - - Group and MOA?
Group 4 - Growth Regulator
Clopyralid - - Group and MOA?
Group 4 - Growth Regulator
Fluroxypyr - - Group and MOA?
Group 4 - Growth Regulator
Triclopyr - - Group and MOA?
Group 4 - Growth Regulator
Quinclorac - - Group and MOA?
Group 4 - Growth Regulator
Diuorn - - Group and MOA?
Group 7 - Photosystem II inhibitor
Mesotriopne - - Group and MOA?
Group 27 - HPPD Inhibitor
HPPD Inhibitor - What is the MOA?
Prevents plants from producing pigments which leads to chlorophyll degradation.
Photosystem 2 inhibitors are what group and what do they do?
Group 5,6 & 7. a.i.’s bind to proteins and inhibit photosynthesis.
PPO Inhibitors are what Group and what do they do?
Group 14. Disrupt cell membranes causing the to leak, dry up and die.
Are PPO inhibitors systemic?
They have limited translocation and are referred to as contact herbicides.
Are Photosystem 2 inhibitors systemic or cantact?
They are taken up by shoots and roots and are translocated only through the Xylam.
PPO Inhibitors - - Group and MOA?
Group 14. Cell membrane disruptors
Carfentrazone - Group and MOA?
Group 14 - PPO Inhibitors (cell membrane disruptors)
Sulfentrazone - - - Group and MOA?
Group 144 - - PPO Inhibotor (cell membrane disruptor)
Flumioxazin - - Group and MOA?
Group 14 - PPO Inhibotor (cell membrane disruptor)
Diquat - - Group and MOA?
Group 22 - Photosystem 2 electron diverter (cell membrane disruptor)
What is the MOA of Group 22? what do they do?
Photosystem 2 Electron Diverter. They disintegrate cell membranes and cause rapid dessication.
Is Diquat a systemic or contact herbicide?
Contact. It doesn’t translocate
What group are Prodiamine, Pendimethalin and Trifuralin in?
Group 3 - (Dinitroanalines) Seedling root growth inhibitors. (Cell division inhibitors)
What is group 3?
Dinitroanalines - Pendi, Prodiamine, trifuralin,
What group is Dimension in?
Pyroxasulfone - - Group and MOA?
Group 15. Long chain fatty acid inhibitors.
Are group 15 herbicides systmic or contact?
They are typically a pre-emergent and do not translocate into the plant. Grasses take it up through shoots and broadleaf weeds through the roots.
Bromacil - - Group and MOA?
Group 5 - (Uracils) Photosystem 2 inhibitor
What groups are Photosystem 2 inhibitors ? examples:
5,6, & 7. Bromacil, Diuron, Simazine
