Interpretive Summary: Ascochyta blight is a persistent problem in chickpea production in the Palouse region of northern Idaho and eastern Washington. Fungicide sprays have been a traditional practice in managing the disease. Experiments were carried out in the field to evaluate five commercial fungicides (Priaxor, Headline, Quadris, Proline and BAS 70004F) of different fungicide classes for their effectiveness againt Ascochyta blight. All fungicide applications significantly reduced disease severity of the highly susceptible cultivar Spanish White. The availability of different classes of fungicide will facilitate managing fungicide resistance in the pathogen Ascochyta rabiei.
Technical Abstract:
Field evaluation of five fungicides of different fungicide classes showed that the fungicides can reduce disease severity and increase yield of chickpea. Alternative fungicides to traditional strobilurin fungicides were identified, and can be used to prevent development of strobilurin resistance in Ascochyta rabiei. Fungicides are shown to be an effective management practice in maintaining and increasing profitability of chickpea production.
