Light leaf spot

Establishment ahead of winter is arguably the most critical phase of growing an oilseed rape crop. Key to this is achieving a good plant stand and managing the pest, weed and disease threats.

Of those threats, nothing is as damaging as a severe light leaf spot infection. Losses can top the 1.0 t/ha mark and CropMonitor data shows that since 2008, losses have exceeded that of another key autumn risk, phoma.

CropMonitor data also confirms that light leaf spot is no longer a disease just for those in the north. It is now found in every region and in most seasons is of greater or equal concern as phoma. It’s why control of both is so important.  

Prothioconazole has proven to be the most effective active available, even with the arrival of new modes of action. It still sets the standard in OSR disease control with unrivalled efficacy against light leaf spot, phoma, and sclerotinia. It’s this broad-spectrum activity which makes prothioconazole the cornerstone of oilseed rape disease control programmes and such value for money.
