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.
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
