Abstract

Chickpea is an important pulse food crop in India. It get infected by many fungi where Alternaria alternata (Fr.) Keissl was found to be dominant among the diseased samples collected during investigation. From these samples of Alternaria alternata, wild sensitive (Aa-1) and highly resistant (Aa-11) isolates were identified using carbendazim. Different sulphate and salt sources were used to examine their response to pathogen either stimulant or inhibitory during culture of the pathogen (in vitro). The aim of the present investigation was to evaluate different sulphate and salt sources on disease development of chickpea caused by Alternaria alternata. The radial mycelial growth of pathogen was examined for its response to these sources. The use of sulphate and salt sources when grown on Czapek Dox agar medium, showed variable response during cultural conditions. The response was either stimulant or inhibitory.

Keywords: Chickpea blight, Alternaria alternata, Sulphate and Salt sources.
