Field pea - time of sowing and disease locations
Aims

To identify best sowing time and fungicides strategies in new pea varieties to maximise yields and to improve recommendations from the ‘Blackspot Manager’ disease risk prediction model in different regions by incorporating data from replicated trials.

Key messages
  • The field peas sown at Hart on the season break in 2009, were heavily infected with blackspot and grain yields were reduced by 30% (0.8 t/ha) compared with later sowing times.
  • Sowing peas two to four weeks earlier (late May) than the conventional time (early–mid June) optimises production of Kaspa and the earlier, longer flowering line OZP0602.
  • OZP0602 was generally higher yielding than Kaspa particularly in later sowing treatments.
  • Yield loss from blackspot can be minimised if peas are sown after 60% of airborne spores have been released.
  • The combination of P-Pickel T with two sprays of mancozeb was economic in some cases in the time of sowing trial at Hart in 2009, resulting in an average 7-14% yield gain in Kaspa and OZP0602.
