Fungicide use

Always consult your agronomist and adapt programmes to local conditions.

• T0 - Only needed in extremely high risk disease pressure situations.

• 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 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 as well as providing good disease control and prolonged green leaf retention.

Core fungicide programme

• T0 - Kayak + morpholine (only needed in high risk disease pressure situations)
• T1 - Kayak + Triazole or Strobilurin
• T2 - Amistar Opti + Triazole

Note: Amistar Opti is a co-formulation containing azoxystrobin and chlorothalonil (Bravo).

Agronomic information

Suzuka has an excellent agronomic profile, with tall but stiff straw and very early maturity.

• Tillering ability:  Medium
• Maturity: Early

Drilling dates

• Suitability for early drilling: Good
• Optimum drilling date: 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.

The table above should always be used in conjunction with thousand-grain weight of the seed to calculate the seed rate.

Nitrogen application

Suzuka has good lodging resistance, so will benefit from high amounts of nitrogen, however a managed approach according to site fertility needs to be taken into account.

In a second cereal situation, Syngenta Seeds recommends 170kg/ha N with a split dressing of 50% mid-March, and 50% during mid-April. 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

Suzuka has very good lodging resistance, but PGR’s can be used to promote root development and even the crop.

Syngenta Seeds recommends the use of Moddus plus a chlormequat-based product at GS31.

A second PGR would only be needed in very lush crops or very fertile sites.

 Core guidelines

• GS31-32 – Moddus 0.2 lt/ha + chlormequat 1.25 lt/ha at onset of stem extension.
• GS37 – Moddus 0.3 lt/ha or ethephon + mepiquat chloride 0.1 lt/ha (in high risk situations).

Grain quality

Suzuka has excellent grain characteristics:

Specific weight: 69.5 kg/hl

Screenings % through 2.25mm: 2.9

Screenings % through 2.5mm: 8.5
