Clean seed and seed dressing – an essential first step to managing chickpea Ascochyta locations
Aims

We aim to demonstrate the effectiveness of using clean seed and seed applied fungicide to minimise the amount of Ascochyta in a chickpea crop, and to demonstrate the effectiveness of early season foliar fungicides to keep disease levels at bay.

Key messages
  • Ascochyta did not progress at this site in 2021 due to low rainfall during the warmer part of the season when temperature better suits disease development.
  • Management of Ascochyta remains critical to growing successful chickpea crops and application of an appropriate seed dressing, followed by a foliar fungicide 4-6 weeks later is an essential first step.
  • Overall, yields were very good with a site average of 1.70t/ha.
