Assessment of alternative fungicides for improved blackspot control in field peas locations

To test the efficacy of a range of experimental (unregistered) foliar fungicides against the above strategy in controlling blackspot in field pea in three major production areas of South Australia.


Key messages
  • The optimum agronomic sowing window for field pea coincided with high blackspot risk in many districts of South Australia in 2015.
  • Under such high disease risk situations, growers in low rainfall areas may be best suited to choose alternative break crop options to field pea to avoid significant yield losses through delayed sowing or disease infection.
  • Experimental fungicide treatments with greater efficacy than Mancozeb showed improved blackspot control and significant yield increases over the Nil and Mancozeb treatments in 2015. Further assessment and application approval is still required.
