إنجليزي. Annual surveys of barley and wheat diseases were conducted in Eritrea from 2000 to 2002. The surveys covered six zones of the central highlands where barley and wheat are grown. The main diseases of barley were net-form net blotch, spot-form net blotch, leaf rust and scald. Other, less important diseases were loose smut, covered smut, barley stripe and septoria leaf blotch. Wheat was mainly affected by yellow rust and leaf rust. Loose smut, septoria leaf spot and tan spot diseases were less prevalent. The average incidence of these diseases varied according to the zone. Among barley diseases, net blotch incidence was high in four of the six zones surveyed. Leaf rust occurred at medium incidence in five zones. Loose smut was more severe in the southern highland plains, while covered smut was more common in the south-eastern highland terraces. For wheat, yellow rust incidence was high in two zones. Areas with a high incidence of yellow rust were not necessarily those with a high incidence of leaf rust. Leaf rust was important in the south-eastern and western highland terraces and in the western highland plains. The number of diseases found in the same field varied from 2 to 5. The south eastern highland terraces, the western highland terraces and the northern highland terraces had the highest proportions of individual barley fields with three or more diseases

Esse hanno interessato sei aree delle zone montuose centrali, dove vengono coltivati l´orzo e il frumento. Le principali malattie dell´orzo sono risultate la maculatura reticolare e puntiforme, la ruggine bruna e la rincosporiosi. Altre malattie meno importanti erano il carbone volante, il carbone fisso, la striatura bruna e la septoriosi. Il frumento era affetto principalmente dalla ruggine gialla e bruna. Il carbone volante, la septoriosi e la maculatura del grano erano meno prevalenti. L´incidenza media di queste malattie variava secondo le zone. Fra le malattie dell´orzo, l´incidenza della maculatura è risultata elevata in quattro delle sei aree esaminate. La ruggine bruna era presente con un´incidenza media in cinque zone. Il carbone volante era più grave negli altopiani meridionali, mentre il carbone fisso era più comune nelle terrazze sud-orientali. Per quanto riguarda il frumento, l´incidenza della ruggine gialla è risultata elevata in due zone. Le aree con un´incidenza alta della ruggine gialla non erano necessariamente quelle con una presenza notevole della ruggine bruna Quest´ultima era importante nelle terrazze di altopiano sud-orientali e occidentali e nelle zone occidentali dell´altopiano. Il numero di malattie riscontrate nel medesimo appezzamento variava da 2 a 5. Le terrazze di altopiano sud-orientali, quelle occidentali e quelle settentrionali sono risultate quelle con le maggiori percentuali di appezzamenti di orzo con tre o più malattie.]
