Cereal Fungicide 

OSR usage guidance  


[Proline on Autumn OSR]  [Light Leaf Spot]  [Phoma stem canker]  [Plant biomass] 

Proline should be used as part of fungicide spray programme with Folicur to ensure the best yield from your crop, using the following scheme. Good application timing will lead to the best results.

Dose Recommendations:

Proline should be used at dose rates of 0.35 or 0.5 l/ha

Normally use 0.5L/ha particularly on crops with:

  • high yield/margin potential
  • Increased risk of Light Leaf Spot & Phoma

Only consider 0.35 l/ha on crops with:

  • reduced yield/margin potential
  • reduced risk of Light Leaf Spot & Phoma (varietal susceptibility, location and crop rotation are all factors to be taken into consideration)

Avoid using sub-optimal doses in curative situations to reduce the risk of resistance developing
