Biochemical Changes in Carbendazim Sensitive and Resitant Isolate of Alternaria Alternata Causing Root Rot to Fenugreek (TRIGONELLA FOENUM GRAECUM L.)

Fenugreek (Trigonella foenum graecum L. ) is an important plant grown for its vegetable, fodder and medicinal, was infected by Alternaria alternata (Fr. ) Keissler, causing root rot disease to fenugreek. Carbendazim was used for management of the disease. The carbendazim sensitive and resistant isolates show biochemical variation when assessed against untreated healthy ones. Biochemical constituents like Carbohydrates, starch, reducing sugar, DNA, RNA as well as Iron. Zinc, Copper, Manganese, and Magnesium contents were seen to be reduced due to infection of Alternaria alternata in sensitive and resistant isolates as compared to healthy plant, while Calcium, total ash and polyphenol contents were increased in both of the isolates.
