Husbandry Guidelines
2
Horatio has been added to the 2012/13 HGCA Recommended List as the
joint highest yielding soft milling wheat in treated trials.
Meeting the demands of a range of
domestic and export market criteria,
Horatio has performed well in all HGCA
regions of the UK producing consistent
yields over many seasons and is well
suited to early September sowing.
Horatio meets the requirements of the
traditional soft feed markets, notably the
export specification, and is
acceptable to UK distillers. It will also be
suitable for the biofuel market, as well as
the domestic animal feed market.
An easy variety to manage, Horatio
provides the grower with proven genetic
disease resistance which, when exploited
in conjunction with modern fungicides,
will ensure the threat from pathogens
can be kept to a minimum.
Limagrain introduced the concept of
husbandry guidelines for new varieties
many years ago and there is now
sufficient information to produce this
booklet for Horatio. The first part
provides some background information
on Horatio, the second section pointers
on how best to manage it. The guide is
not intended as a rigorous blueprint, but
provides sufficient technical support to
enable growers and agronomists to
realise the genetic potential offered by
this new and exciting variety.

For many years the UK has demonstrated
its capability to produce high yields of soft
milling wheats. Varieties in this sector
offer a wide range of market options for
the farmer serving the animal feed, export,
distilling and latterly the biofuel markets.
Current HGCA data (Table 1) clearly
illustrates the ability of Horatio to service
these markets. For the soft feed sector,
Horatio produces grain with both a good
specific weight and Hagberg falling
number, an area which has been an
inherent problem with many soft feed
varieties in the past.
Horatio has been placed in the (soft
wheat) category and will meet the
specifications for this market (Table 1).

THE VARIET Y

Pedigree: Alchemy x Oakley
The objective of this cross was to combine
the excellent soft milling and disease
resistance characteristics of Alchemy with
the high yield potential and orange wheat
blossom midge resistance of Oakley and
strengthen the disease profile of each. A
high level of resistance to Septoria tritici
and yellow rust was a priority because of
the increasing difficulties of controlling
these diseases in the field.
Doubled haploid technology was used to
produce Horatio, enabling a true breeding
line to be developed rapidly with the best
disease and grain quality characters fixed
early on in the selection process.
Horatio - Pedigree And Selection

Horatio demonstrates the highest yield
potential within its market sector. This is
seen in its performance in HGCA
Recommended List (RL) trials (Table 2)
where Horatio is 2% higher yielding than
Viscount both with and without fungicide.
Compared with the hard feed JB Diego,
Horatio is 1% better treated and untreated.
Horatio has also been a consistently high
yielding variety in three years of National
and Recommended List trials, a sign of a
stable variety.
Horatio has produced very high
yields throughout the UK in all HGCA
regions and performed well when
sown as a first or second wheat,
giving great flexibility in its position
on farm (Table 3).

When drilled in early-September sown
trials conducted by the HGCA, Horatio
maintained its high level of performance,
being the second highest yielding of all the
varieties tested and yielding 9% above
Grafton and 11% above Claire (Chart 1).

In this trial, Horatio was the highest
yielding of the varieties tested, 1.2 t/Ha

and popular choice for early sowing.

HGCA RL trials are conducted with high
levels of fungicide and PGR input,
designed to keep disease levels to a
minimum and measure the genetic
potential of varieties. The programmes
used in these trials cost in the region of
£200/ha, considerably more than would
be acceptable to farmers who would
typically spend less than half this figure.
Each year, Limagrain UK conducts a
number of ‘farmer trials’ where replicated
plots of varieties are placed in commercial
crops and managed by the grower using
farm levels of inputs. These trials are
designed to supplement the HGCA system
and determine how varieties perform when
given more realistic levels of management.
In 2011 there were 11 farmer trials located
at a range of locations around the UK from
Cornwall to Perthshire. The results (Chart
3) support those from the RL system. They
show Horatio’s high yield potential when
managed as a commercial crop would be,
with a 7% yield advantage over Viscount
and 4% over the hard feed JB Diego when
fungicide treated and 5 to 8% above these
two varieties untreated.

( ) = limited data; R = resistant.
A high level of durable genetic disease
resistance is a key target in the Limagrain
breeding programme.
The table below gives the HGCA disease
resistance ratings for Horatio, Viscount, JB
Diego and Grafton.
Septoria tritici is the most widespread and
damaging disease of winter wheat and
resistance to this disease is the yardstick
by which most varieties are judged.
Horatio has very good resistance to
Septoria which is based on a number of
genes and not dependent on a single
major gene. This genetic resistance should
be used in conjunction with a targeted
fungicide programme to give the highest
level of disease control in the field.
Mildew resistance for Horatio is good and
this disease should not require routine
treatment. Mildew is frequently
associated with early sown, thick crops
and high humidity within the canopy,
which can be avoided by careful
management i.e. using lower seed rates
and careful nitrogen timing.
New races of yellow and brown rust in 2012
have affected numerous varieties, in many
cases we are likely to see ratings being
altered. At the time of writing it is unclear
where the ratings for Horatio will lie, but
they are expected to be lower than
published in the 2012 HGCA
Recommended List.
It is important that fungicide programmes
are targeted effectively to manage any
increased risk. In the case of brown rust, a
programme targeted at Septoria tritici is
likely to give adequate control.
Brown rust tends to be localised, with
certain areas of the country being affected

more frequently than others. Historically,
Brown rust was a late season disease
developing after ear emergence. More
recently, the disease has appeared earlier
in some seasons where the autumn and
winter have been mild. This will need to be
carefully monitored, especially in earlier
sown crops.
The development of eyespot will need to
be monitored on Horatio, with thicker,
early sown crops on the heavier soil types
being most at risk. Lesions penetrating the
stem base are most likely to affect yield
and increase the lodging risk. As a number
of diseases are often present at the stem
base, correct identification is important.
Horatio has good resistance to Fusarium
ear blight and its current rating gives a
score of zero in the HGCA Mycotoxin risk
assessment.
Horatio also has genetic resistance to
orange wheat blossom midge and routine
insecticide sprays will not be required on
the variety.
Horatio has moderately tall straw and
responds well to PGR use, having a similar
rating to JB Diego when treated. It is
recommended that an effective programme
(see page 13) is planned for Horatio in most
situations to ensure its very high yield
potential is realised.
Horatio has a similar ripening date to
Viscount and is earlier to ripen than the
majority of other feed varieties (Table 5).

Horatio has a prostrate winter growth habit
and a moderate to high tillering capacity.
In the early spring Horatio’s growth habit is
similar to Claire. Table 6 shows the growth
habit ratings for a number of soft and hard
feed varieties along with Claire and
Einstein for reference. Horatio’s score of 7
is akin to Claire and it is more prostrate
than Viscount and JB Diego.
In the spring, Horatio moves through the
ear primordial (growing point)
development and stem internode growth
stages slightly faster than Alchemy. Chart 4
compares the ear development stages of
Horatio with Viscount and Alchemy along
with Claire (a slow developer) and Einstein
(a fast developer) for reference. It shows
that Horatio is rated 'medium' in its
development speed, faster than Alchemy
but slower than Viscount and Einstein.

MANAGEMENT
12
The combination of a prostrate growth
habit, medium speed of development with
good standing power and disease
resistance suggests that Horatio may be
sown from early September onwards.
Horatio has produced very high yields in
trials (see pages 6 & 7) when sown at this
time. It will continue to perform well when
sown throughout the autumn and the
latest safe sowing date for Horatio is the
end of February.
SOWING DATE
Seed rates for Horatio should reflect the drilling date and seedbed conditions.
These seed rates (Table 7) are based on
sowing into seedbeds where
establishment is likely to be good. Under
less favourable conditions they should be
increased by 40–50 seeds/m2 to allow for
losses during establishment.
SEED RATE
All Horatio seed should receive a ‘single
purpose’ seed treatment as routine in
order to control the commonly occurring
seed borne diseases. For earlier sowings,
broad spectrum dressings offering
improvements in standing power and early
season foliar disease protection should be
considered in high risk situations. Where
take-all risk is high, a disease usually
associated with second and continuous
wheat situations, specific seed treatments
such as Latitude or Jockey may be of
benefit and worth considering.
Insecticide seed dressings such as Deter
can provide good early season protection
against aphids carrying barley yellow
dwarf virus and help to reduce grain
hollowing by slugs. Where crops are drilled
in the early part of September, an
additional aphicide spray may also be
required later in the autumn to maintain
protection.

Horatio has medium length straw and
responds well to PGR use, having a rating
of ‘8’ when treated, the same as JB Diego.
Where expected yields are likely to exceed
8t/ha, a routine application of a
chlormequat (CCU) based product will
provide a very cost effective insurance
against possible lodging and associated
loss of yield and quality.
Limagrain recommend a split PGR
application with 2/3 at Zadoks GS30 (or
more precisely 'glume primordial stage')
and the balance, GS31 ('first node
detectable') as an ideal input for Horatio. If
the weather does not permit a split
application, full rate CCC should be applied
at GS31. The addition of Moddus or
Canopy should be considered, especially if
the crop has a very high yield potential to
further reduce crop height and lodging
risk. Earlier sown crops are more likely to
benefit from the additional PGRs.
Where soil type, fertility, seasonal growth
and previous experience suggest a high
lodging risk then a late season ethephon
based product (such as Terpal) could be
used.
A managed approach should be adopted
with Horatio to reduce lodging by using a
combination of the appropriate seed rate,
controlling stem base diseases and correct
nitrogen timing in conjunction with early
spring PGR applications.
Horatio - Plant Growth Regulator Use
Preliminary testing suggests that Horatio is
likely to be tolerant to chlorotoluron (CTU)
based products but further evaluation is
required before a full recommendation can
be made. Growers are advised to contact
their agrochemical supplier before treating
Horatio crops to check the latest situation.
Recent research work has shown that
wheat varieties can vary in their ability to
suppress blackgrass and that variety
choice should be part of a blackgrass
control strategy. The more competitive
varieties have good ground cover in the
autumn, a prostrate growth habit and grow
quickly in the spring to help suppress
blackgrass. Horatio has these
characteristics and its competitiveness
against blackgrass was measured in a trial
in 2011 (Table 8, overleaf ). There were
fewer blackgrass plants surviving a
comprehensive herbicide treatment in the
Horatio plots than in the Oakley and JB
Diego plots.
Horatio - Herbicide Tolerance
14
Nitrogen recommendations for winter
wheat have recently been updated to
reflect recent trial results, NVZ regulations
and the relative prices of grain and
fertiliser. In particular, allowance can now
be made for the high yield potential of
varieties like Horatio when calculating the
total amount of nitrogen fertiliser to apply
and comply with ‘N max’ limits.
With increasing scrutiny on nitrogen use it
is imperative growers can justify the
amount applied and should refer to Defra
RB 209, HGCA Guidelines or SAC Technical
Note 625 (as appropriate) and use a FACTS
qualified adviser when calculating the
rates to be applied to Horatio.
A three-way split nitrogen application will
be more reliable than a two-split approach.
The ideal target applications are based on
the actual growth stage of the crop and
coincide with Zadoks GS30 (glume
primordial stage) GS31/32 (terminal
spikelet) and GS 37 (flag leaf emergence).
The first application of nitrogen should
consist of no more than 50kgN/ha in most
cases and should be used with care on
Horatio. This dose can increase the threat
from disease and lodging; it could be
reduced (or even omitted) if the crop was
in a fertile situation where too much early
fertiliser would be detrimental. Well
tillered (> 1000/m2) crops do not need
nitrogen fertiliser at this stage.
However, in second or continuous wheat
crops, where a possible threat from take-
all exists, an increased first nitrogen
application would be desirable to reduce
the impact of any infection that might
occur.
The second application should be targeted
just prior to Zadoks GS32 or to be more
accurate, at the terminal spikelet stage.
Horatio - Crop Nutrition
Following the dry spring in 2011, theblackgrass population was considerablylower than would be expected. The trialdoes indicate the differences between
varieties where grassweeds occur and howcorrect variety choice can play a role in anoverall control strategy.

15
Careful monitoring of the crop stage,
especially in earlier drilled crops is
essential for the correct timing of inputs.
This should be the main nitrogen
application, in the region of 100kgN/ha.
The third application close to flag leaf
emergence (Zadoks GS37) delivers the
remainder of the nitrogen required for
maximum yield.
In simple terms the breakdown of the three
split applications is 25% / 50% / 25%.
Sulphur
It is now well accepted that sulphur
deficiency is present in many soils in the
country and therefore sulphur applications
are desirable on most crops. Crops at
highest risk from sulphur deficiency are
those grown on the lighter soils (chalks or
sands), particularly where organic
manures are not used. Deficiency is
becoming more widespread and it is likely
most wheat crops will benefit from a
sulphur application.
The best approach is to apply 15 - 20
kgS/ha (equivalent to 40 - 50 kgSO2/ha) in
the early spring but before stem extension.
This may be combined with the first
nitrogen application or split between the
first and second applications. Later
applications of sulphur may not be as
effective in dealing with sulphur deficiency
in wheat crops.
Trace elements such as manganese,
copper, boron and iron are important
during periods of rapid growth, especially
around flag leaf emergence. Foliar
applications of products such as Multimin
will ensure that any transient deficiencies
are met and will aid flowering
synchronisation. The use of magnesium at
T3 will help with grain fill and improve
specific weight.
At the time of writing grain prices arehigher, but more volatile, than have beenseen for many years. With the prospect ofhigh gross margins from wheat crops,using a sensible fungicide programme onHoratio will deliver an excellent return onthe investment. In HGCA RL trials over afive year period, including some highdisease pressure years, Horatio has shownan average response of 13% - equivalent to
1.3t/ha – from a comprehensiveprogramme.
Fungicide programmes for Horatio shouldbe targeted and take in to account itsgenetic resistance to the individualdisease outlined earlier. The aim shouldbe to keep the crop clean to the groundbut the flag leaf and top two leaves areparticularly important with respect to grainfilling. It is essential that Septoria tritici is

controlled very effectively and cropsreceive adequate protection againstmildew and eyespot.
Horatio is likely to benefit from fungicidesapplied at the following timings:
TO (Pre GS 30)This fungicide is frequently used as anearly pre-season ‘clean up’ and as aninsurance to help with diseasemanagement later on, particularly asapplication with the first part of asequential PGR programme is possible(see page 13).
Horatio is unlikely to require a routine TOtreatment but an application ofchlorothalonil will help to delay Septoriadevelopment. Where disease levels in thecrop at the end of the winter are high theaddition of a low dose of a triazole couldalso be considered.
T1 (GS31-32)The main disease to be targeted at thistime will be Septoria tritici and thefungicide should be applied to keep thefinal leaf three disease free. Sprays shouldbe based on a triazole (e.g. Opus orProline) using at least a half label ratemixed with chlorothalonil. In Limagraintrials, Tracker has produced good resultswhen applied at this stage. Strobilurinchemistry could be included if there is athreat from brown rust.
TO and T1If either mildew or eyespot is present atthe TO or T1 timings these will need to becatered for in the fungicide mix. A numberof very effective mildewicides are availablei.e. Talius. Flexity has activity on mildew
and eyespot, and Proline and Tracker areeffective against eyespot and Septoria.
T2 (GS37 – 39)Aimed at keeping the top two leaves cleanand maintaining Septoria control, triazolessuch as Opus or Proline with chlorothalonilhave proved to be very reliable at thistiming. On Horatio, which has goodresistance to Septoria, there is scope touse lower rates than on other moresusceptible varieties but it is importantthat sufficient fungicide is applied at thistime to maintain green leaf area of theupper leaves.
In crops with a high yield potential orwhere Septoria pressure is high, the newSDHI fungicides (Adexar, Aviator XPro andSeguris) could be used where theirpersistence and effects on green leafretention are most likely to be of benefit.
Strobilurins are frequently included in thefungicide mix at the T2 timing. On Horatiotheir contribution to disease control will befor brown rust and their physiologicaleffects may be useful.
T3 (GS60 +)An ear emergence fungicide will bevaluable on Horatio to maintain earlierdisease control, provide protection againstspecific ear diseases and help to improvespecific weight.
A number of products are available for eardisease control with those based onProline ± a strobilurin performing well atthis timing. A quarter to a half label doseis appropriate for additional diseasecontrol. A minimum of half dose isnecessary for Fusarium control.

In addition to the Farmer Trials mentioned
earlier, Limagrain conduct their own
Agronomy Trials to investigate the
response of varieties to different fungicide
regimes. In 2011, Horatio was included in
these trials and treated with a
comprehensive range of fungicide
programmes. Although the trial was a first
cereal drilled in good time, disease
pressure was very low and the site
suffered from a lack of rainfall during much
of the spring growing season.
The treatments were:
• The HGCA programme, designed to keep
disease levels to a minimum and
measure the genetic potential of a
variety
• A relatively inexpensive triazole based
programme
• Programmes from Bayer, BASF and
Syngenta, based largely on triazole
chemistry with the inclusion of
strobilurins at T2 and T3 (Bayer and
Syngenta) or ‘stacked’ triazoles (BASF)
• As above but with the addition of the
new SDHI chemistry
Full details of the treatments are given in
Table 9, along with an indication of the
cost/ha.
18
The HGCA programme produced the
highest yield at 10.0t/ha with the triazole
programme only 0.17t/ha lower. The
triazole/strobilurin mixtures from the three
manufacturers had similar yields and were
all about 0.7t/ha behind the HGCA
treatment. The SDHI treatments were also
lower than the HGCA – by about 0.6t/ha -
and gave very similar yields to the non-
SDHI treatments from their respective
manufacturers.
The picture changes when a margin over
fungicide cost (yield x £/tonne {£160} –
fungicide cost) is calculated. The high
yielding and low cost triazole programme
had the best margin of £1497/ha. The
second best margin (£1422/ha) came from
the intensive HGCA programme where the
additional cost was partly offset by the
higher yield. The differences between the
respective manufacturers programmes
with and without SDHIs were relatively
small, with only £45/ha between the
highest and the lowest, suggesting there
was no financial benefit to adding either a
strobilurin or SDHI treatment to a good
triazole programme to Horatio in this trial.
Although the results were influenced by
the season and low disease pressure, they
do show the importance of matching
fungicide use to the genetic resistance
inherent in a variety such as Horatio and
how this is reflected in the final margin.
The yields and margin over fungicides for the trial are presented in Chart 5.
