Cropland Uses
Annual weed control prior to crop emergence or in summerfallow - all crops.
Quackgrass control - prior to seeding or after harvest.
Canada thistle control - summer-fallow, shelterbelts and post-harvest.
Dandelion control - prior to crop emergence or post harvest.
Other perennial weeds control - summerfallow, shelterbelts and post-harvest.
Spot treatments (in-crop) of perennial weed control - cereals, corn, soybean and forages.
Pre-harvest control of quackgrass, Canada thistle, milkweed, toadflax, dandelion, season-long control of perennial
sow-thistle, and harvest management.
Weed control in glyphosate tolerant crops: canola, corn and sugar beet.
Post-harvest stubble treatments - all crops.
Weed control in non-crop areas: industrial, right-of-way, recreational and public areas.
Brush control, turf renovation, directed application in woody nursery stock, roadsides and shelterbelts.
