Abstract:
Lentil anthracnose disease incited by Colletotrichum lentis Damm is one of the most significant fungal threats to lentil (Lens culinaris Medikus) cultivation worldwide. No detailed data on lentil anthracnose presence and its impact with reference to Pakistan is available. Thus an extensive two years (2014, 2015) disease survey was carried to figure out the scenario of lentil anthracnose in thirteen major lentil growing districts of the Punjab province namely Rawalpindi, Chakwal, Attock, Jhelum, Gujrat, Sialkot, Narowal, Mianwali, Khushab, Jhang, Bhakkar, Layyah and Muzaffargarh. Consequently, 162 samples (80 during 2014; 82 during 2015 crop season) were collected from private lentil farms and the government research institutes. Two-three random samples depending on farm size were taken. Districts mean disease incidence (DI) and disease severity (DS) was calculated. Disease was found in 100% areas/locations visited. At individual locations, the maximum mean DI 85 % and DS 9 was found at Noorpur Thal (2014), whereas the minimum DI 5 and DS 3 was observed at Bhadder (2014). Year-wise, the maximum districts mean DI of 69 % and DS 7 was noted in Khushab (2014), while the minimum districts mean DI 19% and DS 3 was observed in Gujrat (2014). Based on two years data, the highest districts mean DI 68% & DS 7 was recorded in Khushab followed by Sialkot DI 63% and DS 7, however the lowest DI 21% and DS 3 was observed in Jhang. Locations/districts with the highest disease intensity require appropriate support for lentil anthracnose management.
