------- First reported from Pakistan in 1989 (Geddes, 1989). National survey of chilli production (2014-15) showed an average of 10% incidence of wilt detected in 76% of fields inspected. Maximum disease incidence of 16.4% recorded in Sindh province followed by Punjab (11.4%), Khyber Pakhtoonkhwa (7%) and Baluchistan (4.5%). Prevalence ranged between 5% and 19.5% with maximum prevalence in Indus delta and minimum in Western dry mountains. Isolates identified as biovar 3 (81%) and biovar 4 (19%) were probably R. pseudosolanacearum [phylotype I].
