Proline on Light Leaf Spot


[Proline on flowering OSR]  [Canopy Management]  [Sclerotinia]  [Alternaria] 

While the main timing for controlling light leaf spot is during the late autumn and early spring, after a mild winter there can still be disease pressure in late spring, which reduces green leaf area and damages the forming flowers.

According to the independent Appropriate Fungicide Dose trials published by HGCA, Proline is the strongest light leaf spot treatment currently available, so although fungicide choice at flowering is generally driven by other diseases such as Sclerotinia, an application of Proline at this time will control any Light Leaf Spot infection that is present.
