Mango gummosis disease incidence studies under natural and artificial conditions

V Suresh, B Vidya Sagar, P Kishore Varma and SR Koteswara Rao

A planned survey was conducted to assess the incidence of gummosis in the major mango growing areas of Telangana, Andra Pradesh viz., Krishna, Khammam, Rangareddy, Medak in 2012-13. During the survey conducted in different mango orchards symptoms like gummosis, dieback and vascular discoloration were mostly observed. Among the orchards surveyed maximum per cent disease incidence was recorded 13.3 per cent in Chinnarasam at Rekunta village of Krishna district followed by Suvernarekha (Rekunta), Navaneetham (Aswaraopet), Manjeera, Khader pasand (Sangareddy) recorded 10.0 per cent of gummosis incidence and less incidence was recorded in varieties kobbarimamidi, Baneshan (Rekunta) (2.00 per cent) in natural condition. One year old seedlings of ten different varieties of mango viz., Chinnarasalu, Manjeera, Tellagulabi, Totapuri, Baneshan, Alphonso, Amrapali, Imampasand, Suvernarekha, Pandurivari mamidi were screened for against Lasiodiplodia theobromae laid out in a Randomized Block Design. Among these cultivars, Suvernarekha showed highly susceptible to mango gummosis with disease severity of 84 per cent followed by Chinnarasalu, Manjeera and Tellagulabi showed 50 per cent disease severity. Baneshan, Alphonso, Imam pasand and Pandurivari mamidi have shown moderately resistant reaction.
