Crops, Rates and Staging:
pH adjuster: 1 packet per jug of imazamethabenz to be used.
Imazamethabenz up to 0.67 L per acre (16.1 acres per jug):
• Barley, spring wheat (including durum): 1 to 6 leaf stage.
• Annual ryegrass (seed production only): 4 to 6 leaf stage.
Imazamethabenz at 0.34 L per acre (32 acres per jug):
• Sunflower: 2 to 8 leaf stage. Crop must be less than 15 inches (38 cm) tall except for semi-dwarf varieties, which must
be less than 12 inches (30 cm), and dwarf varieties, which must be less than 4 inches (10 cm). Stunting and head
deformation can occur from applications made beyond recommended stages.
Maximum one application every two years of Assert 300SC or Avert or other products containing imazamethabenz.
When tank mixing, always check the tank mix partner recommendations for additional staging restrictions. Refer to the
product label for complete mixing instructions.
A general guide to mixing can be found on page 8.
Weeds, Rates and Staging:
Weeds Stage Rate
(L per acre) Acres per
10.8 L jug

Weeds above plus:
Buckwheat (wild and tartary) (suppression)
Volunteer canola (except Clearfield varieties)
Up to 4 leaves 0.54 20
Wild oat
1 to 3 leaves
Wild oat 1 to 4 leaves 0.67 16
* Main stem leaves.
Application Information:
• Water volume: In cereals only, imazamethabenz may be applied in 20 to 40 L of water per acre when applied alone or
when tank mixed with dichloroprop/2,4-D, 2,4-D ester, or MCPA ester. For all other applications, apply in 40 L per acre.
• Nozzles and Pressure: 40 psi (275 kPa) when using conventional flat fan nozzles. Low drift nozzles may require higher
pressures for proper performance. Use a combination of nozzles and pressure designed to deliver thorough, even
coverage of ASABE medium droplets or larger.
• Screens: Use 50 mesh screens for nozzles and in-line filters.
How it Works:
Refer to Table 9 on page 48.
Effects of Growing Conditions:
DO NOT apply imazamethabenz 24 hours before or after a frost. It works best at warm temperatures. Performs relatively
consistently under dry conditions. If cold, wet soil conditions persist in the days after application, retillering of wild oats may
occur. DO NOT apply to drought stressed sunflowers.
Tank Mixes:
Herbicides:
Imazamethabenz may be applied at either 0.53 L or 0.67 L per acre in tank mixes in the brown and dark brown soils, but
must be applied at 0.67 L per acre when tank mixing in the black and grey wooded soils for adequate wild oat control.
