Description

Abstract: Diseases are major constraints to groundnut production throughout the world. This handbook is designed to assist agricultural research and extension workers, who may have limited formal training in plant pathology, to make a tentative diagnosis of diseases of groundnut caused by 31 fungi, 2 bacteria, 9 viruses, a mycoplasma-like organism, 4 nematodes, and a parasitic flowering plant (Alectra vogelii). The most characteristic field symptoms of each disease are illustrated and described. It is emphasized that for confirmation of a field diagnosis, the assistance of skilled plant pathologists will be required in most cases. Authors’ Summary.
