Abstract
To monitor Tikka or Cercospora leaf spot disease of groundnut, surveys were carried
out in the groundnut areas of four major districts of Pothwar region viz. Chakwal,
Attock, Jhelum and Rawalpindi during main crop season in 2017. To assess
prevalence and incidence of Tikka disease, 997 farmer’s fields were visited. Clear
disease symptoms were noted in the fields during the season. The disease prevalence
ranged from 7.85 to 45% where highest prevalence was recorded in district Jhelum
(45%) and lowest in Attock (7.85%). The disease incidence also varied and ranged
from 9.35 to 22.48%. The highest mean disease incidence (22.48%) was observed in
district Chakwal, whereas the lowest (10.57%) was observed in district Rawalpindi.
The results of the study indicated that Tikka disease is significantly distributed in all
the major groundnut producing districts of Pothwar region therefore, timely and
possible management strategies are of vital importance to control this potential threat.
