Aims
  • The current trials aimed to evaluate the efficacy of a range of unregistered foliar fungicides, including new actives, which have previously shown improved levels of disease control and yield benefit over the current industry practice.
Key messages
  • The recommended field pea industry practice of P-Pickel T® (PPT) seed treatment and 2 foliar fungicides of Mancozeb (Manc.Std) failed to significantly reduce disease infection levels or increase grain yield over untreated control treatments under high blackspot disease pressure in 2016.
  • Early disease control applications (four weeks after sowing) were important for reducing initial blackspot infection levels at Minnipa, conversely later spring applications were important at the higher rainfall site of Hart.
  • Over two consecutive years, a yield benefit of at least 15% has been obtained from application of new experimental fungicide actives over the current industry practice treatment of two foliar sprays of Mancozeb.
  • Further research is required to understand the interaction in efficacy between fungicides and timing of disease infection, together with the drivers of ascochyta blight onset and progression in different field pea growing environments.
