Disease Resistance

Sequel has an outstanding disease resistance profile to all the major diseases, mildew, net blotch and Rhynchosporium along with BaYMV resistance, a crucial factor in certain areas of the country.

Fungicide Use

Getting disease control right is vital to achieving maximum yields.

- Only need in extreme high risk situations as resistance is good for mildew and Rhynchosporium.

- T1 timing is the key for protecting the canopy during the plants' main spring growth period.
Competition from disease at this time reduces the development of potential grain sites.
Use Unix + triazole or strobilurin for broad spectrum disease control. Triazole should be added when the variety is showing high levels of brown rust.

- This is the time to protect green leaf and prolong grain filling. Premature senescence through disease and abiotic leaf spotting reduces yield and increases losses through screenings and specific weight. Bravo has been demonstrated to have affect against biotic and abiotic leaf spotting.
Strobilurins (i.e Amistar) deliver broad spectrum disease control and prolong green leaf retention, while triazoles provide curative control of disease.

CORE PROGRAMME

T0	- Unix + Tern (only in high risk situations)
T1	- Unix + Triazole or Strobilurin
T2	- Amistar Opti + triazole

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

Agronomic Information

Good all round agronomics offer an easy and flexible variety to grow, with early maturity and with good straw strength and length – a requirement from many livestock growers.

Drilling Dates

Suitability for early drilling - Good
Optimum drilling dates - Mid September - early October
Suitability for late drilling (December) - Good (very vigorous)

Recommended Sowing Rates

Seed rates are dependent on soil conditions, rotation and 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 suggested number of seeds per square metre that should be planted under good conditions.

table-6

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

Nitrogen Application

Apply enough nitrogen to maximize yield potential. The quantity required will depend on soil reserves, but NFC recommend as a general rule in a second cereal situation 170kg/ha N with a split dressing of 10% at the end of February, 50% mid March and 40% during mid April.

PGRs

Sequel is regarded as a medium risk variety in terms of lodging, hence NFC would recommend the use of PGRs at GS30-31. On very lush crops, or very fertile sites, a second PGR at GS32-37 may be required.

Core Guidelines

Moddus 0.1 - 0.2 (0.2l/ha) + chlormequat (1.25l/ha) at onset of stem extension (GS30-31) Followed by (in high risk situations) an Ethephon based product at GS34 - 37

Quality

Sequel is a six row feed variety, but with exceptional specific weight for a six row.
