الملخص

During the last three growing seasons (1970/71. 71/72, 72/73), a survey of wheat and barley diseases was carried out in the western part of Libya. Diseases observed were the stem rust, leaf rust of wheat, leaf rust of barley, bunt, loose smut, covered smut of barley, flag smut of wheat, powdery mildew, and some barley leaf spots. These diseases occur in different degrees of severity according to the crop, the cultivar and the prevailing environmental conditions. The flag smut of wheat and some of the barley leaf spots were observed for the first time in Libya and this is the first record of these diseases.
