This guide is a compilation of published information for the identification and scoring of diseases of selected mountain crops (amaranth, barley, beans, buckwheat, finger millet, foxtail millet, proso millet and rice) in Nepal. As this guide is intended for the crops grown in the mountain region, it does not cover all the diseases known to occur in the country. Also, disease information on some of the crops, especially proso millet, foxtail millet, buckwheat and grain amaranth, is very limited. As a result, the disease information of these crops might not have been sufficiently covered in this guide. Some of the diseases included in this guide have not been reported in Nepal, but they are included because of their likely occurrence in the mountain climates.
