Precautions

Liberty 200SN can be applied from the cotyledon to the early bolting stage of canola.
For use only with canola seed designated as "Liberty Link canola".
Ammonium sulphate can be applied at 6 L/ha (2.4 L/ac)(liquid) or 3.3 kg/ha (1.3 kg/ac)(dry) for improved control of specific weeds.
Do NOT add oil or any other surfactants.

Precautions

For use only with pedigreed (certified) canola seed designated as "Roundup Ready Canola".
Apply up to the 6-leaf stage of the canola. A second application may be made for later flushes emerging after the initial application and for improved results on perennial weeds.
The higher rate should be used when weeds are larger, when weed pressure is high and for perennial weeds.

**Pursuit + non-ionic surfactant + liquid fertilizer**

Precautions

For use on imazethapyr tolerant canola only.
Apply early postemergence when the crop has at least one fully expanded leaf and before the weeds reach the 2 true leaf stage.
PURSUIT will provide residual weed control from soil activity.
Some rotational cropping restrictions apply.

Precautions

Provides season long top growth control of Canada Thistle and control of wild buckwheta.
For use only with pedigreed (certified) canola seed designated as "Roundup Ready Canola".
Lontrel is recommended for use ONLY on the following cultivars: Cyclone, Ebony, Jewel, 48A65 and Hyola 401.
Apply when canola is in the 2-6 leaf stage
Apply in 100 L/ha (40 L/ac) of water
