Blight control in potatoes

Published: June 24, 2021, 6 a.m.

Factors such the loss of key fungicides and new emerging blight variants are all challenging established blight control practices and on this week\u2019s Tillage Edge podcast, Michael Hennessy was joined by Shay Phelan, a potato Specialist in Oak Park, to discuss blight control in potatoes.\n\nThe loss of Mancozeb as a key blight control product puts pressure on the existing products and Shay recommends growers should sit down early in the season to sequence the use of these products to ensure maximum label use is not exceeded throughout the season. \n\nShay then explained that the new blight variant (37A2) now means Fluazinam (or Shirlan) cannot be relied upon to give the same level of blight protection and should only be used in mixtures with other fungicides. \n\nHe also added that the blight forecasting model used by Met Eireann is now improved following research carried out by Teagasc in Oak Park, Carlow.\n\nFor more episodes and information from the Tillage Edge podcast go to:\nhttps://www.teagasc.ie/crops/crops/the-tillage-edge-podcast/\n\nProduced on behalf of Teagasc by LastCastMedia.com
