What group is Dimension in?
26
Pyroxasulfone - - Group and MOA?
Group 15. Long chain fatty acid inhibitors.

Group 2. (sulfonurea) ALS Inhibitors.
31
What group are ALS Inhibitors, what do they do, are they systemic or contact?
Group 2. Inhibit Branch Chain Amino Acid production. Absorbed by roots and shoots and translocate via Xylam and Phloem.
32
