"A new disease in Jatropha curcas L. plants was observed\r\nduring the summer season in 2009 and 2010 in\r\nplantations in several Indian states, including Andhra\r\nPradesh, Assam, Chhattisgarh and Madhya Pradesh.\r\nThe outbreak of the disease coincided with the leafdropping\r\n(dormant) stage of the crop, which sets in\r\nwith the increasing moisture stress. Affected J. curcas\r\nplants showed drying along with shrivelling, and discoloration\r\nof the stem with sticky reddish-brown exudation\r\nat the base of the plants. Black lesions (soft and\r\nrotting) on the stem under the bark and cambium\r\nlayer were also observed. From the affected stem\r\nparts, fungal cultures were isolated and tested for\r\ntheir pathogenicity on pot-grown plants. The fungal\r\nisolates caused symptoms on J. curcas leaves and petioles\r\n(black spots, 1–3 mm in diameter). Then they\r\nspread to the stems causing shrivelling and gummosis\r\nof hard-wood stems, and finally led to the death of the\r\ninfected plant. The causal fungus was identified as\r\nBotryosphaeria dothidea using microscopic observations\r\nof hyphae and spores, and internally transcribed\r\nspacers (ITS) sequencing technique. In addition, four\r\nother fungal isolates were also isolated from the affected\r\ntissues, which were identified as Macrophomina phaceolina,\r\nPhomosis longicolla, Fusarium oxysporum and\r\nAlternaria alternata using the ITS sequencing technique.\r\nThe role of these fungal cultures, i.e. whether\r\nthey grow as saprophytes on the affected dead tissues\r\nor have any role in causing the black rot disease, needs\r\nfurther study. Spraying J. curcas plants showing early\r\nsymptoms of this disease with Bavistin (carbendazim\r\n50% WP) at the rate of 2 g l–1 water controlled the\r\nspread of the symptoms and led to the recovery of\r\nplants with new leaf growth after the rains."^^ .
