High yielding winter malting barley with BaYMV resistance
Yield potential
Purdey is a high yielding, two-row winter malting barley which performs well across all regions and soil types. It is HGCA recommended for the for the East region as well as having a specific HGCA recommendation for growers wanting a BaYMV resistant variety for malting.

Fungicide use
Always consult your agronomist and adapt programmes to local conditions.
It is important to control mildew and brown rust and Purdey will benefit from a standard fungicide programme.
- T0 - The T0 spray prevents diseases gaining a foothold in long growing seasons or where disease pressure is high.
- T1 - The use of Bontima at T1 will provide clean, stress-free lower green leaves to build yield potential.
- T2 - Bontima at T2 gives outstanding protection against disease and leaf spotting for green leaf retention, securing yield potential and increasing quality by driving grain size and grain fill.
Core Programme
- T0 - Spiroxamine three quarter to full rate
- T1 - Bontima 1.6 lt/ha (in a high mildew pressure situation include Flexity at 0.5 lt/ha)
- T2 - Bontima 1.6 lt/ha
Agronomic information

Growth habit
- Over winter: Semi-prostrate
- Tillering ability: Medium/high
- Maturity: Late
- Suitability for early drilling: Can be drilled early, but be cautious of disease levels during early spring
- Optimum drilling date: Late September
Recommended sowing rate
Seed rates are dependent on soil conditions, rotation and time of drilling: the more difficult the environment the higher the seed must be to compensate for potential plant loss. The table below shows the suggested number of seeds per square metre that should be planted under good conditions.
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 100-120 kg/ha with a split dressing. Syngenta Seeds recommends 40 kg/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
Purdey has good straw strength characteristics, with short straw and good resistance to lodging.
GS31-32 ~ Moddus 0.1 lt/ha + chlormequat 1.25 lt/ha at onset of stem extension
On fertile sites consider Terpal 1.0 lt/ha (ethephon + mepiquat chloride) at GS37
Grain quality
Purdey produces big grain and has a specific weight which is very similar to Pearl. Grain nitrogen levels sit between Flagon and Pearl. Purdey has high hot water extract.

Harvesting
Top priority – with all quality crops it is critical to harvest the crop in the best condition as soon as moisture is correct. As with all malting barleys, the variety should be kept separate to prevent contamination and to maintain the maximum premium from the end product.
Storage management
Correct storage of malting barley is a priority to ensure harvest quality remains. Malting barley should be at a moisture of below 14.5% to minimise the risk of moulds and dried in such a way so there is no damage to germination.
Grain temperature and moisture should be checked regularly to ensure quality is maintained and germination levels are kept at 98% plus.
