KEEP SPRAY INTERVALS TIGHT IN CEREALS

• T2 is the major yield-building fungicide timing, as the flag leaf contributes around 42% to yield.
• Applied at flag leaf emergence (Growth Stage 39), T2 sprays aim to control disease on the flag leaf and eradicate infections on Leaf 2. Key fungicides at this timing are strobilurins and triazoles.
• With the earlier season, advanced crops and high disease pressure, it is important to keep the spray intervals tight between T1 and T2 as well as keeping the effective dose rate up.

ARMA ENHANCES THE PERFORMANCE OF EVERY STROBILURIN

• Independent trials at TAG showed at least a 0.5 t/ha yield benefit from the use of ARMA with Amistar (azoxystrobin) and Landmark (kresoxim and epoxiconazole).
• ARMA also enhances the performance of Mantra (kresoxim, epoxiconazole + fenpropimorph), Twist (trifloxystrobin), Acanto (picoxystrobin), Opera (pyraclostrobin + epoxiconazole) and Tucana/Comet (pyraclostrobin).
• The majority of yield benefit from strobs is thought to come from physiological greening effects. Trials clearly show that ARMA when added to half rate fungicides improves the green leaf area, which can boost yield and specific weight.

ARMA ENHANCES THE EFFECTIVE DOSE OF BOTH STROBS AND TRIAZOLES

In order to manage the widespread resistance problem to strobilurins and the performance drift of triazoles, these fungicides must be used at robust and effective dose rate. Trials and commercial use have demonstrated that ARMA enhances the effective dose rate of a wide range of straight and coformulated fungicides used at T2 timing.
This table shows the extra yield given by adding ARMA to a range of different cereal fungicides.

The positive effect of the addition of ARMA

ARMA helps to achieve good coverage, better retention and quicker penetration into the crop, so allowing the fungicide to do its job to best effect.
