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

• Management of Ascochyta remains critical to growing successful chickpea crops and application of an appropriate seed dressing followed by foliar fungicide 4-6 weeks later are essential first steps
