Broadway® Star


Broadway® Star delivers an outstanding performance in winter wheat against yield robbing grassweeds including wild oats, ryegrasses and bromes PLUS the bonus of controlling an extensive range of broad-leaved weeds.

How to make the most of Broadway Star:
1.  Leading product for Ryegrass, Brome, Oats and Broad-leaved weeds
2.  Use as part of a programme
3.  Use with a residual partner
4.  Apply to a small target weed (optimally 1-3 leaf)
5.  Apply to active growth (2-3 days either side of application)
6.  Soil temperature ideally 8°C (minimum of 6°C)
7.  Ensure optimal application techniques are followed:

  • Pre tillereing: 130-150 L/ha, FINE-MEDIUM spray quality, CFF, VPFF, Defy nozzles
  • Tillering: 150 L/ha, MEDIUM spray quality, CFF, VPFF, twin fluid nozzles

Key considerations: 
Active growth; Size of (grass) weeds; mix with a residual; attention to detail when spraying; avoid stressed crops.

2023 Brome questionnaire results: 

February 2024 news:

Hundreds of farmers, contractors and agronomists have indicated that brome is a growing threat in the battle against grassweeds in UK arable fields.

New data from a Corteva Agriscience survey shows that 80% of respondents have populations on their farms with the vast majority estimating it to be infesting up to 25% of their winter wheat area in 2023.

Cultural control methods such as rotational planning, delayed drilling and ploughing are being deployed on every farm involved in the research, and the brome problem has been shown to exist in all the main wheat-growing regions of England, Scotland, Wales and Northern Ireland. 

Alister McRobbie, Cereal Herbicides Category Manager, said: “This work provides more clarity on how widespread brome issues are and the various approaches being taken to reduce populations...  continue reading

Corteva would like to thank all brome questionnaire respondents. Insights and feedback will continue to drive our work in developing solutions that support winter wheat growers as well as enabling us to give technical advice and support when it is needed most.
