The area under Tomato (Lycopersicon esculentum Mill.) cultivation is on the increase due to its fleshy fruits with high nutritive value. It occupies number one position in its nutrient contribution to human diet. In Tamil Nadu, tomato is grown in an area of 22,433 ha, with a production of 2,82,912 tonnes and a productivity of 12,611 kg/ha. The crop is known to be affected by a number of diseases among which, early blight caused by Alternaria solani (Ellis and Martin) causes yield losses up to 80% . The disease manifests as leaf spots with dark brown to black concentric rings which later coalesce and results in blighting of leaves; defoliation and shedding of immature fruits. Also, dark spots and sunken lesions appear near the base of stem resulting in stunting and girdling of stem. Presently, the management of tomato early blight disease has been done with the application of chemical fungicides.
