Firefly 155 New Formulation for 2010

Firefly 155 is a simple, one-pack fungicide designed to fit the needs of the grower looking for a broadacre solution for first class Septoria and rust control at the flag leaf (T2) spray timing on winter wheat.

It's formulated to deliver exactly the right ratio of the Septoria azole prothiocoanzole and rust active strobilurin fluoxastrobin for T2 in one 10L pack.

Product Profile

How do I use Firefly 155?

To get the best out of Firefly 155 at T2, and save time and waste from using a single pack solution use:

• 1.3 L/ha on crops with moderate disease risk
• 1.5 L/ha on crops with high Septoria and/or rust risk

These simple dose choices deliver the right ratio of active ingredients for the T2 timing. They also provide you with the security of proven Septoria credentials of prothioconazole plus the most active rust strobilurin, fluoxastrobin. Both active ingredients uniquely contribute towards canopy greening, and are formulated to secure exceptional crop coverage and rain-fastness.

What can I expect from T2 Firefly 155 vs current standards?

Reading across from previous datasets from Firefly (100g/l prothioconazole + 50g/l fluoxastrobin), Firefly 155 would be expected to deliver equivalent or better performance. Comparing 150g/ha prothioconazole + 75g/ha fluoxastrobin against the current standard 0.75 L/ha epoxiconazole + 0.4 L/ha pyraclostrobin (200g formulation) 2008 (12 BCS, and independent trials), high Septoria and rust pressure

• 67% of trials favoured Firefly (average yield benefit = 0.5t/ha)
• 8% of trials were equivalent
• 25% of trials favoured epoxiconazole + pyraclostrobin (average yield benefit 0.1t/ha)

Taking into account all 12 trials, Firefly secured an average extra 0.25t/ha, worth about £2,500 /100ha extra margin over fungicide cost @ £100/t wheat.

Yield advantage to Firefly (t/ha)

Mean of 12 Trials 2008:  1.5 L/ha Firefly vs 0.75 L/ha EPX + 0.4 L/ha pyraclostrobin 200.

Although the best return on investment is delivered at T2, Firefly 155 can be used at T1 where early rust is a key focus. If Septoria and stem base disease risk is high, aim to use a minimum of 150g/ha prothioconazole (e.g. 1.3 L/ha Firefly 155).

Firefly 155 is an ideal upgrade for a general purpose 'foliar top-up driven' T3 spray, where mycotoxin risk is low and there is a need for a top-up for Septoria and brown rust control on the flag leaf. Use 0.75 to 1.0 L/ha.

Where mycotoxin risk is moderate to high, a prothioconazole only (Proline 275) approach is critical. This is because fluoxastrobin, although having some activity on true Fusarium at label doses, does not deliver the outstanding broad ear blight activity of prothioconazole - which is where £/ha spend should be diverted.
