Diseases severity assessments
Percentage of leaf spot incidence of sesame at pre and post-emergence stages were calculated. Pre-emergence (%) was
based on the number of non-emerged seeds in relation to the number of sown seeds, while post-emergence (%) was
based on the number of plants showing disease symptoms in relation to the number of emerged seedlings. Observation
on disease severity percentage was recorded after 7 days of pathogen spray following 0-5 scale of Shrestha et al.
(2005), where 0= no infection, 1=1-5% area covered by the disease, 2= 6-10% area covered, 3= 11-20% area covered,
4= 21-30% area covered, 5= 31-100% area covered. The experiment was repeated thrice.
