The book is a study that was carried out during the 2011-12 season
to identify the fungal seed-borne pathogens and/or diseases in seed
samples of peanut, pearl millet and sorghum collected from farm
saved samples of different zones of Eritrea. Seed samples were
tested for germination, fungal infection and pathogen frequency in
the laboratory. Disease intensity on plants was assessed at 2-week
intervals from the time disease symptoms appeared in the field for
a period of 10 weeks. Seed germination percentage was high in pearl
millet (97%) followed by sorghum (93%) and groundnut (91%). Seven
pathogenic fungal genera were Alternaria, Aspergillus, Fusarium,
Helminthosporium, Mucor, Penicillium and Rhizopus. Percent
frequency of seed-borne fungi was higher in groundnut (73%) and
minimum in sorghum (15%). Diseases observed in the field were
Cercospora leaf spot (Cercospora personata and C. arachidichola) in
groundnut, downy mildew (Sclerospora graminicola) and rust
(Puccinia penniseti) in pearl millet, anthracnose (Colletotrichum
graminicola) and covered smut (Sphacelotheca sorghi) in sorghum.
