@ T0
- One in five growers have adopted
a T0 spray to provide protection against early
diseases. In the South and Southwest a much higher
proportion
of farmers use an early treatment in wheat.
- A T0 treatment is usually applied
at around Growth Stage 30-31 and is an insurance
spray to reduce or
delay Septoria, mildew and yellow rust.
- Key fungicides used at T0 are low
dose triazoles in combination with chlorothalonil.
If mildew is
present,
a specific mildewicide is added.
Trials
with chlorothalonil in tank-mix with either epoxiconazole
(Opus), kresoxim-methyl + epoxiconazole (Landmark)
or azoxystrobin (Amistar) clearly show that the addition
of Arma results in even more yield.
Amistar + Bravo resulted in an extra
yield benefit over the untreated of 31% but with the
addition of
Arma this rose to 34%.
Landmark plus Bravo gave 36% more
yield over the untreated, but with the addition of
Arma this was raised to 41%.
Opus plus Bravo gave a 25% yield
improvement over untreated and with Arma in the tank
this increased to 29% more
grain.
This extra benefit from Arma pays
for itself many times over and ensures the best performance
and better persistence
from contact fungicides and their partner triazoles.
Septoria Control
Opus + Bravo and Arma
Arma
in mix with T0 fungicides:
|
| • helps to
retain and spread the fungicides onto the leaf
surface |
| • improves
placement of contact fungicides onto the plant |
| • helps penetration
into the plant where it is needed - rainfast in
30 minutes |
| • works at
low temperatures when T0 treatments are applied |
| • ensures
the most robust fungicide performance |

@ T1
- T1 sprays are applied at emergence
of leaf 3 (Growth Stage 31/32)
- They are aimed at the control of any
disease, particularly Septoria, on the recently emerged
leaf 3 and provide
protection on leaf 2.
- Leaf 2 contributes around 8% to grain
yield, with leaf 3 adding 23% so keeping these leaves
free from disease
ensures good potential yields.
- Key fungicides at T1 are triazoles,
where doses between half and three-quarter rates
are used. If eyespot is
a particular risk, a specific eyespot spray can
be applied.
Triazoles form the backbone of many fungicides programmes,
especially when strobilurin resistance is so rife.
Arma has been shown in trials and commercial usage
to enhance the performance of all triazoles. Useful benefits
are seen with all triazoles, although the most substantial
increases are in combination with the most soluble
triazoles.
Septoria Control
Fungicides and Arma
Slippa, the organosilicone ‘super-spreader’,
improves fungicide performance by reducing surface tension
and by giving over 20 times greater spread than a standard
wetter.
This means that the fungicide reaches parts of the
cereal plant, which would otherwise be inaccessible,
controlling
the stem-based disease directly and improving control
of other diseases, such as mildew, which may act as
a reservoir of infection for the upper crop canopy.
Trials work on winter wheat with flusilazole-based products
and cyprodinil (Unix) have shown the benefit of Slippa. Eyespot Control
