Proline Eyespot  

Proline Eyespot

Eyespot

Overall protection with Proline goes up from soil level - with unequalled activity against the stem-base disease complex. Not just W & R eyespot, but sharp eyespot, Fusarium and Microdochia too. (That's crucial, because if just one stem-base disease is removed, levels of another can increase.) With Proline, you cover the whole complex. Proline has been proven to outyield epoxiconazole+boscalid at T1. All this, plus exceptional Septoria control too!

  • Eyespot is at best suppressed and when present at high levels needs ¾ to full label doses of eyespot active products to be effective. For Proline this would be 0.6\L/ha to 0.8L/ha.
  • Eyespot is difficult to visually assess, especially the R-type and there's lots of variations between different people assessing different trials. Often, visual disease scores do not relate to final yield, so its always important to match visual disease assessments with final yield (see graph below).
  • Eyespot epidemics are fairly sporadic (www.cropmonitor.co.uk) , but a 50% disease index can result in 0.75t/ha yield loss. The biggest yield losses are from eyespot induced lodging.

It's worth comparing this with Septoria, where losses of up to 5t/ha were recorded in 2008! So focus on Septoria and add on the eyespot capaibility. 0.6L/ha Proline is the ideal choice.


Data source: 2008 SAC Perth eyespot trial. 52% eyespot index.

This graph  illustrates the need to correlate visual disease scores with yield. So although epoxiconazole +boscalid appears to give better visual disease control in this eyespot trial, Proline gave much better yields with a clear dose-response.

Yield advantage to PTZ 9t/ha)
Source: 8 BCS trials 2008. 0.6L Proline vs 1.125L epoxiconazole + boscalid.  Wheat at £110/t.

In ¾ of comparative trials in 2008, 0.6L/ha of Proline outyielded and equivalent rate of epoxiconazole+ boscalid,  from 0.4-1.0t/ha. The average yield benefit was 0.3t/ha, worth about £3300/100ha with wheat at £110/t.
