Abstract

Broomrapes (Orobanche sp.) are root holoparasitic plants causing severe damage to various families of horticultural crops. A Preliminary survey was carried in tomato fields infested with orobanche in Potohar plateau of Pakistan. Results indicated that each planting bed comprising10-12 tomato plants contained 7-8 parasitic weeds. Overall survey indicated the 65-70% plants suffered partial or complete yield loss. Further, it was estimated that the number of weeds inhabiting plant-1 was ranged from 2-4. Yield loss was estimated at 57.17 tons/ha while in terms of financial loss, it was 2579.87 $/ha. Hence total estimated loss on the total surveyed area of 16 hectares was 41395.85 $. The high potential of tomato cultivation in Pakistan reinforces the urgent protection measures to resolve this emerging issue.
