Can you afford to skip protection at T0?
In many situations this season, the question of whether a T0 treatment may be beneficial is becoming clearer, as reports from across the UK have already confirmed early symptoms of septoria and rust in a high proportion of crops. Where these symptoms have been noted, or where crops are being grown in a high-risk scenario (for example a susceptible variety that was sown early) , the best strategy for keeping ahead of disease is to apply protection before spores have had a chance to move up the developing plant.
This season, the best form of attack is defence! This means applying a fungicide treatment at T0.
Start clean with T0 protection
In circumstances where septoria is the primary driver for a T0 treatment, ARIZONA® (500 g/l folpet) is the ideal option: this proven multi-site fungicide can be used either as a standalone product to protect against septoria or as a tank mix partner with other modes of action.
Including ARIZONA® (500 g/l folpet) at the T0 timing is recommended in the following situations:
- A standalone application of ARIZONA® can be used to protect Leaf 4 against septoria.
- Where there is an additional threat of rust, ARIZONA® should be used in conjunction with a strobilurin
- If active rust is present in the crop, ARIZONA® should be used alongside an appropriate azole to provide the best levels of control.
In all these scenarios, using ARIZONA® (500 g/l folpet) at T0 will provide peace of mind by ensuring crops have been protected if/when subsequent T1 applications are delayed.
Key benefits of ARIZONA® at T0
- Provides contact protection against septoria to safeguard new growth
- Acts on spore gemination and re-sporulation to reduce disease movement up through the canopy
- ARIZONA’s multi-site mode of action supports resistance management and helps to protect the longevity of partner products
- ARIZONA® doesn’t interfere with the curative kickback activity of partner products
- Adds useful early protection against yellow and brown rust as well as intrinsic activity against mildew (for rust control, always use ARIZONA® in mixture with a rust active partner)
- ARIZONA® delivers a reliable return on investment by extending green leaf area duration, resulting in higher yields and enhanced crop quality.
Don’t leave yield behind
Applying ARIZONA® at T0 has been proven to deliver significant improvements in terms of crop yield. In the following example, using ARIZONA® as a tank mix partner alongside Univoq lifted yields by 0.48 t/ha compared to the same programme without a T0 treatment, and by 0.58 t/ha compared to the standard programme without ARIZONA® at any timings.
In the following scenario, including ARIZONA® at T0 added an additional 0.22 t/ha compared to its inclusion only at T1 and T2, and lifted yields by 0.44 t/ha compared to the core fungicide programme without any ARIZONA® at any timing.
ARIZONA®: when margin matters, choose performance that pays
ARIZONA® (folpet 500 g/l) is a unique multi-site fungicide that provides valuable protection against key diseases in wheat and barley including septoria, rhynchosporium, ramularia and net blotch alongside useful activity on yellow and brown rusts.
ARIZONA® delivers a reliable return on investment through enhanced disease control, and safeguards the efficacy of partner products as part of an anti-resistance strategy.
