| CROP | WEED | STATE | WEED STAGE | RATE L/ha | CRITICAL COMMENTS |
| :--- | :--- | :--- | :--- | :--- | :--- |
| Wheat, Linseed, Triticale, Canola, Safflower, Rye, Barley | Annual (Wimmera) Ryegrass | All States | 2 to 4 leaf | 1 | Apply generally 3 to 4 weeks after sowing, when cereals usually 2 to 5 leaves. For barley, apply only when crop is 4 to 5 leaf stage. Add wetting agent at 0.25% a.i. to water in spray tank. This is irrespective of volume of water/ha or rate of Crowbar Herbicide. Do not add wetting agent if mixing with some other sprays (refer compatibility). |
| | Common Barbgrass | NSW, ACT Only | | 1.25 | |

| | Common Barbgrass | NSW, ACT Only | | 1.25 | |
| Wheat, Linseed, Triticale, Safflower, Rye, Barley, Canola | Wild Oats | All States | 2 to 3 leaf | 1.5 | For barley, apply only when crop is 4 to 5 leaf stage. Avoid double spraying (overlap) at the maximum rate of 1.5L/ha. In crops other than barley, use 2 L rate if most weeds 3 to 4 leaf and if spraying 4 to 6 weeks after sowing, especially in northern NSW and Qld. Add wetting agent as above. |
| | | | 3 to 4 leaf | 2 (not barley) | Use 1.5 L rate only if growing conditions are very favourable and weeds are 2 to 3 leaf, 3 to 4 weeks after sowing, and cereals usually 2 to 3 leaf. |
