Survey results of apple growing areas in Himachal Pradesh revealed that the highest severity of Smoky Blight Canker (SBC) occurred in Shimla, Sirmaur and Kullu districts while that of Nail Head Canker (NHC) in Kinnaur and Lahaul & Spiti districts. Pink Canker (PC) was uniformly distributed in all the districts with exceptionally high intensity in Kullu. The SBC thrived better at winter (October-March) temperature of 0-15°C/summer (April-September) temperature of 15-20°C as well as high mean rainfall during summer months (April- September) in Shimla, Sirmaur and Kullu (respectively 176, 226 and 123 mm). NHC flourished at 0°C and below, supported by drought and frosty conditions during winters and low annual rainfall in summer months in Kinnaur (58.3 mm) and Lahaul & Spiti (26 mm). PC established under a wide range of  temperature and rainfall conditions with tendency to be more severe in high annual mean temperature in winters and high annual mean rainfall areas of Kullu (1377 mm) followed by Shimla (1515 mm) and Sirmaur (1648 mm). On the other hand, it prevailed with comparatively lesser severities in drought prone and less rainfall areas of Kinnaur (801 mm-annual mean) and Lahaul & Spiti (443 mm-annual mean).Downloads
