Effects of Sulphate and Salt Sources on the Development of Alternaria alternata Causing Root Rot Disease to Fenugreek

Nilkanth K. Khandare ^[4] | S. S. Kamble

Abstract: Fenugreek (Trigonella foenum- graecum L. ) is an important plant grown on different regions of India for its vegetable, medicine and fodder source. It get infected by many fungi where Alternaria alternata (Fr. ) Keissler, was found to be dominant among the diseased samples collected during investigation. From these samples of Alternaria alternata, wild sensitive (Aa-2) and highly resistant (Aa-8) 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 present investigation was to evaluate sulphate and salt sources on disease development of fenugreek caused by Alternaria alternata. The linear 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. But certain source was proved to be a beneficial candidate against the test fungus which is beneficial for cultivar.
