Abstract : The effectiveness of four fungicides viz., Benlate [benomyl], Topsin-M [thiophanate-methyl], Daconil [chlorothalonil] and Cuprocaffaro [copper oxychloride] at 10, 20, 50 and 100 ppm against Botryodiplodia theobromae and Colletotrichum gloeosporioides [Glomerella cingulata] associated with die back disease in mango was evaluated in vitro. Benlate at 100 ppm and Topsin-M at 50 ppm completely inhibited the colony growth of B. theobromae, whereas Benlate at 100 ppm proved effective against C. gloeosporioides. The first foliar spray of Topsin-M at 1.0 g/litre, Daconil at 2.50 g/litre and Cuprocaffaro at 2.50 g/litre of water in September on 10- to 12-year-old plants reduced the inoculum of B. theobromae and C. gloeosporioides up to 80 and 56.66%, respectively. A total of four foliar sprays along with application of well rotten farmyard manure, chemical fertilizer and canal irrigation effectively controlled the disease.
