Sclerotinia risk is low as spores have yet to be detected, plus humidity and temperature criteria risks are still low – they have only exceeded the 21-hour threshold in Wick and Kirkwall so far. If warmer temperatures and higher humidity coincide with flowering that will increase the risk, which will be further increased if flowering is prolonged and /or if weather is wet over that period.
In addition to your own on-farm assessment, you can check sclerotinia infection risk at two monitored sites in the Borders and Lothians on AHDB‘s website.
