Yield potential
WINSOME is high yielding with malting potential.
| Variety | UK treated yield % (100% = 8.6t/ha) |
UK untreated yield (100% = 6.7t/ha) |
|---|---|---|
| WINSOME | 100 | 98 |
| Flagon | 98 | 101 |
| Pearl | 98 | 96 |
| Sequel | 102 | 101 |

Disease resistance
WINSOME has an outstanding disease resistance profile: all ratings at 7 or above.

As Flagon and Pearl, WINSOME is not BaYMV resistant.
Fungicide use
To enhance grain fill, yield potential and grain quality, WINSOME would benefit from a standard fungicide program.
- T0 - Needed only in extreme disease pressure situations.
- T1 - 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 where the crop is showing high levels of brown rust.
- T2 - Protect the green leaf and prolong grain filling. 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 an effect against biotic and abiotic leaf spotting as well as providing good disease control and prolonged green leaf retention.
Consider:
- T1 - Kayak 1.0lt/ha + ½ rate Triazole
- T2 - Amistar Opti 1.25lt/ha + ½ rate Triazole
Agronomic information
WINSOME is early maturing and has shorter, stiffer, straw than Flagon or Pearl.

Growth habit
- Over winter: Semi-prostrate
- Tillering ability: Medium/high
- Maturity: Early
- Suitability for early drilling: Good
- Optimum drilling date: Mid-late September
Recommended sowing rate
Seed rates are dependent on soil conditions at the time of drilling: the more difficult the environment, the higher the seed rate must be to compensate for potential plant loss. The table below shows the number of seeds per square metre that should be planted in good conditions.
| September | October | November | December | |
|---|---|---|---|---|
| England | 325 | 350-375 | 375-425 | 425 |
| Scotland | 350-375 | 375-400 | - | - |
This table should always be used in conjunction with thousand-grain weight of the seed to calculate the seed rate.
Nitrogen application
Most commercial malting barley growers use between 100-150kg/ha with a split dressing. Syngenta Seeds recommends 40kg/ha in mid to late February and the remainder to be applied by the end of March. These figures are for guidance purposes only. You must work with your agronomist when calculating nitrogen rates and timings, taking into consideration end market requirements and the fertility of the field. You should also work within any DEFRA guidelines/restrictions.
PGRs
WINSOME has good straw strength characteristics; with good resistance to lodging, leaning and necking. WINSOME also has shorter straw than existing market leading malting barley varieties.
In normal situations consider:
- GS31-32 ~ Moddus 0.2 lt/ha + Chlormequat 1.25 lt/ha at onset of stem extension
On fertile sites consider applying Terpal 1.0lt/ha (Ethephon + Mepiquat chloride) at GS37.
