Seventeen Latin American isolates were studied for virulence characteristics on a group of 21 bean cultivars. Large differences in virulence were found among isolates for disease severit, lesion size, lesion umber, sporulation capacity, and number of days required to cause a given level of disease. No cultivar was resistant to all isolates of the pathogen; however, regression analyses indicated that several cultivars such as A 339 and BAT 1647 show presence of several components of non-specific resistance.
Part of a series which presents papers of topical interest relating to the breeding of plants important to agriculture and horticulture.
The Indian Society of Mycology and Plant Pathology, which is consistently striving to serve the fraternity of plant pathology with its all round efforts, has recently undertaken an arduous but zealous project to start the publication of series of Annual Reviews in the discipline. The basic philosophy to start the publication of annual reviews has been to make available the latest developments in the different areas of the discipline to the students, scientists and libraries.
The book entitled “Disease Problems in Vegetable Production” 2nd edition, is specifically prepared for under and post graduate students in Agriculture/ Horticulture and range of professionals including teachers, researchers, extension plant pathologists and elite vegetable growers. The book gives a comprehensive over-view of economic importance, symptomatology, etiology, pre-disposing factors and management of vegetable diseases employing cultural, biological, host resistance, plant extracts and chemical methods as such and in anintegrated approach so that the ravages due to the diseases remain below economic threshold level. A total of 19 chapters dealing with important diseases of vegetables like potato, tomato, crucifers, cucurbits, pea, French bean, chillies and bell pepper, onion, garlic, eggplant, carrot, sugar beet, colocasia, okra and leafy vegetables have been compiled in this book. Two new chapters on diseases of ginger and diseases of vegetables under protected cultivation as well as some important diseases of different vegetable crops left out in the first edition have been added in this edition. Besides, the book also includes chapters on common pathogens of vegetable crops, disease problems in nurseries, post harvest diseases and diseases caused by nematodes. All chapters have been updated in the light of available literature up to 2017. Symptoms, disease cycles of important diseases and different structures of pathogen(s) have also been given in the book that will not only help in better diagnosis and understanding of the perpetuation and spread of the causal pathogens but will also help in the management of these diseases more effectively. Coloured photographs of disease symptoms have also been included for easy identification of vegetable diseases.
Legumes provide one quarter of the world's crop protein, and the diseases which afflict them have a tremendous impact worldwide. This important collection examines the diseases of the major legume crops. Each chapter provides a review of a particular crop and its principal diseases. The chapters include discussions of etiology, biology, symptoms, epidemiology, crop loss and control, as well as extensive references. The book opens with an overview of legumes and their role in agriculture and concludes with a discussion of new disease management techniques. Written by leading experts from throughout the world, it is an indispensable resource for plant pathologists.
