For brome, complex grass weed and broad-leaved weed situations
Pacifica is the most effective spring herbicide available for the control of mixed grasses and broad-leaved weeds in winter wheat. Used appropriately Pacifica can provide a real solution for complex weed situations, enabling wheat profits to be maintained and weed seed return minimised. Pacifica controls a wide range of grass weeds and broad-leaved weeds.

Weed spectrum
Pacifica controls a wide range of grass and broad-leaved weeds. For most grass and all broad-leaved weed situations Pacifica is recommended at 400 g/ha. The following label weeds are susceptible to Pacifica:
| Post-emergence susceptibility of weed at 400 g/ha | |
| Black-grass | to GS29 (resistant populations) to GS39 (susceptible populations) |
| Wild-oats | to GS39 |
| Anual meadow grass | to GS31 |
| Rough-stalked meadow-grass | to GS31 |
| Perennial rye-grass (from seed) | to GS32 |
| Italian rye-grass (from seed) | to GS32 |
| Sterile brome | Moderately resistant to GS33 |
| Great brome | Moderately resistant to GS33 |
| Rye brome | Moderately resistant to GS30 |
| Common Chickweed | to Branching Stage (10cm across/ high) |
| Mayweeds | to Branching Stage (10cm across/ high) |
| Charlock | to GS16 (6 expanded true leaves) |
| Volunteer oilseed rape | to GS16 (6 expanded true leaves) |
Pacifica is recommended at 500 g/ha where brome is the overwhelming constituent of the weed spectrum.
