Abstract : Mango bacterial canker disease, caused by Xanthomonas campestris pv. mangiferaeindicae, has become increasingly important in the Kakori and Malihabad mango belt of India. In this area disease appeared during Jun.-Jul. Control in relation to weather conditions revealed that spraying of streptocycline at 300 p.p.m. with copper oxychloride 0.3% was better than streptocycline at 300 p.p.m. and other treatments when applied on fruits during May when temp. ranged between 17.0-48.0°C and RH 25-100%. Spraying of chemicals before the rains during May reduced inoculum and controlled disease build-up significantly. The varieties Amin Dophasla, Amin Kurad, Bhodia (north Indian varieties), Baramasi Apus, Bombay, Cherramani, Chandrakaran (south Indian varieties), Afeem (east Indian varieties) and Dadamio, Hansaraj, Mankurad, Nawabulamdi (west Indian varieties) were highly susceptible and could be identified as risk varieties on which timely control measures are essential.
