Objective

To investigate the effect of fungicide application timing and frequency on the control of ascochyta blight in the new generation of chickpea cultivars with partial resistance to Ascochyta rabiei. To compare the efficacy of different fungicide rotations on ascochyta blight control.

Outcome

Experiments confirmed that accurate timing of fungicide applications was critical, demonstrated in the significant differences among 3-spray application regimes. Experiments also clearly demonstrated the superior performance of recently developed cultivars over the older generation of chickpea cultivars. Fungicide rotation had no effect on ascochyta blight control or yield in 3 of 7 station years.
