Abstract

First report of Curvularia lunata causing leaf spots on Sorghum bicolor from Pakistan.

Abstract

In October 2012, reddish brown, oblong lesions with chlorotic centres were observed on the leaves of sweet sorghum in Punjab, Pakistan. Early symptoms appeared as reddish brown circular spots on the leaves. These spots increased in size and coalesced to form oblong lesions. Entire fields were severely affected by the disease. The causal pathogen was identified as Cochliobolus lunatus based on morphological, genetic (ITS) and pathogenicity analyses. This is thought to be the first report of C. lunatus leaf spots on sweet sorghum in Pakistan.
