Fungicide treatments and the number of applications applied for each treatment to assess control of Ascochyta blight (AB) in chickpea at Nhill during 2020.

Grams of active ingredient per hectare.
Preventative sprays were applied before rainfall events, at key growth stages (fourth node and late vegetative/early flowering stage), to maximise foliage protection. Post infection sprays were applied when the first AB lesions were observed and at flowering. Trials were inspected at least weekly.
The full control treatment is a rotation of fungicide actives (Chlorothalonil, Tebuconazole + Azoxystrobin, and Bixafen + Prothioconazole) at the rates quoted in the above table applied every 2–3 weeks to ensure minimal to no disease occurred in these plots as a control in the experiment.
In addition to the fungicides listed an additional podding Chlorothalonil at 1,080 gai/ha was applied to protect seed quality with at least 5 mm of rainfall forecast within 48 h during podding, as per the standard industry recommendations.
