Bacterial leaf spot of guar

Abstract

In January 1963, severe leaf spotting was seen in a planting of guar (Cyamopsis tetragonoloba (L.) Taub.cv.Texsel) near Brisbane. Lesions were initially watersoaked but dried quickly to pale brown irregular spots with a narrow dark tan margin, surrounded by a diffuse pale green halo. Smaller punctiform spots uniformly dark were also present. Puckering was associated with the lesions on younger leaves.
