Fungicide use
- T0 - Needed if there are signs of early disease pressure.
- T1 - T1 timing is the key for protecting the canopy during the plants' main spring growth period, as during this time competition from disease reduces the development of potential grain sites. The use of Kayak + a triazole or strobilurin based product gives a broad-spectrum of disease control. Triazole should be added in a curative situation or the where the crop is showing high levels of brown rust.
- T2 - T2 application is to protect green leaf and prolong grain filling as premature senescence caused by disease and abiotic leaf spotting reduces yield and increases loss through screenings and specific weight. Bravo has been demonstrated to have affect against biotic and abiotic leaf spotting, good disease control and prolonged green leaf retention.
Core fungicide programme
- T0 - Kayak + Tern if required
- T1 - Kayak + Triazole or Strobilurin
- T2 - Amistar Opti + Triazole
Note: Amistar Opti is a co-formulation containing azoxystrobin and chlorothalonil (Bravo).
Agronomic information
Bronx has a good agronomic profile, with good straw length and early maturity.

Growth habit
- Over winter: Semi-prostrate
- Tillering ability: High
- Spring vigour: Rapid
- Maturity: Early
Drilling dates
- Suitability for early drilling: Good
- Optimum drilling date: Late September
Recommended sowing rate
Hybrid barley is drilled at a low seed rate to maximise the potential of hybrid vigour.
Bronx should be sown at 200-210 seeds per square metre.
Nitrogen application
Bronx should receive the same amount of spring nitrogen fertiliser as a conventional winter barley feed crop for the site. However, an early application is advised to maintain and promote tiller growth.
As a general rule we advise:
- 20% of the total middle to end February (GS21-25)
- 50% of the total in mid-March (mid tillering, GS26-29)
- 30% of the total in mid-April (GS30-31)
If a drought reduces N uptake, then consider the application of a further 20% in mid-May (flag leaf emerged).
PGRs
Recommendations vary from site to site, but a PGR programme should be based around:
- GS31-32: Moddus 0.2lt/ha + chlormequat 1.25lt/ha
- GS37: Terpal 1.0lt/ha
Where sites are medium to heavy land and/or fertile we recommend a split dose, as below:
- GS29-30: Moddus 0.1lt/ha + chlormequat 1.0lt/ha
- GS30-32: Moddus 0.1lt/ha + chlormequat 1.0lt/ha
- GS37: Terpal 1.0lt/ha
Grain quality
Bronx has a good all-round grain quality profile with big grain and above average Specific Weight.
