Changes in total chlorophyll, total soluble sugar, reducing sugar and non reducing sugar were observed in five different cultivars ofmustard in response to powderymildewviz, Skm-9801, skm-9804,GM-1,Varuna and Skm- 9818 at different stages of disease infection. In fungicide treated plant ie. Control plants significantly higher value for total soluble sugar, chlorophyll and reducing sugar where as reverse trend obsereved in non reducing sugar content in all cultivars.Among the different cultivars no similar trend was observed in diseased infectional stages.
