Precautions

Apply PP, PPI or PRE.
Under preplant uses, a tank-mixture with glyphosate may be used to control emerged weeds.
Do NOT apply to coarse textured soils with less than 2% OM.
Can be tank-mixed with glyphosate or Gramoxone for PP burndown of emerged annual and perennial weeds, see Chapter 6, for more information.

Precautions

Apply PP, PPI or PRE. For PPI treatments uniformly incorporate with equipment set to work at a depth of 5-8 cm.
For PP treatments in minimum or no-till systems apply up to 21 days before planting.
Can be tank-mixed with glyphosate for PP burndown of emerged annual and perennial weeds, see Chapter 6, for more information.
Do NOT apply to areas where the soil pH is >7.8 and organic matter < 2%.
Do NOT apply to soils containing more than 5% organic matter.
Sufficient rainfall to moisten the soil to a depth of 5 cm should be received within 7-10 days for optimum weed control.
This formulation separates into 2 phases over time. Shake container before using.
Some rotational cropping restrictions apply (Table 4-3 (PDF - 80K) and Table 4-4 (PDF - 82K)).

Precautions

Apply PRE
Do NOT incorporate.
For light textured soils - apply at 1.6 L/ha.
For medium textured soils - apply at 2.3 L/ha.
For heavy textured soils - apply at 2.35 L/ha.
Control of Yellow foxtail is achieved when Command is applied at 2.3 to 2.35 L/ha.
Do NOT use on Natto soybeans.
Some rotational cropping restrictions apply Refer to Table 4-3 (PDF - 80K) .

Precautions

Apply PPI or PRE.
Can be tank-mixed with glyphosate for PP burndown of emerged annual and perennial weeds, see Chapter 6, for more information.
For use on medium and heavy textured soils only.
See Pursuit for additional comments.

Precautions

Apply PP, PPI or PRE.
Can be tank-mixed with glyphosate or Gramoxone for PP burndown of emerged annual and perennial weeds, see Chapter 6, for more information.
Some rotational cropping restrictions apply (Table 4-3 (PDF - 80K) and Table 4-4 (PDF - 82K)).
Addition of non-ionic surfactant and liquid fertilizer is required if emerged weeds are present at application.
For preplant applications:
- apply Pursuit at 0.168 L/ac;
- apply up to 30 days prior to planting;
- For minimum tillage, only one working of the soil to prepare a seedbed is recommended following application. Make this final seedbed preparation no deeper than 10 cm and do not turn untreated soil to the surface.
For preplant incorporated applications apply Pursuit at 0.125L/ac.
For preemergence applications, heavy infestations of ragweed and/or barnyard grass require a tank-mix.
For preplant incorporated applications heavy infestations of lamb's-quarters, ragweed or barnyard grass may require a tank-mix.
Do NOT apply as preplant incorporated application more than one year in sequence.
Use only once per season.

Precautions

Apply PPI.
Allow 24 months between applications.
See Pursuit for additional comments.
Refer to Table 4-3 (PDF - 80K) and Table 4-4 (PDF - 82K) for rotation restrictions.
