Plasmodiophora Brassicae The Cause Of Cabbage Hernia

With A Biographical Sketch By The Translator. Phytopathological Classics, No. 4.

The book is presenting a comprehensive information on fundamental, and applied knowledge of Plasmodiophora brassicae Woronin. infecting cruciferous crops, and weeds. Clubroot of crucifers has spread over more than 88 countries of the world with average annual loss of cruciferous crops from 10-15 per cent at global level. It is considered as a disease of cultivation since once introduced in a field, its inoculum piles up year by year in the form of resilient resting spores of P. brassicae which spreads in the field through field operations. This disease is very unique since the pathogen can survive in the soil in the rhizosphere of non-host plants in addition to its main host cruciferous species, cultivated or wild. This book complies inclusive information about the disease, its geographical distribution, symptoms, host range, yield losses, and disease assessment scales. The book also explores host-parasite interactions in the form of seed infection, disease cycle, process of infection, pathogenesis, epidemiology and forecasting. Chapters discuss the genetic and molecular mechanisms of host-parasite relationships, management practices including cultural, chemical, biological control practices, and other integrated approaches. The book is immensely useful to researchers, teachers, extension specialists, farmers, and all others who are interested to grow healthy and profitable cruciferous crops all over the world. Also the book serves as additional reading material for undergraduate and graduate students of agriculture and especially plant pathology. National and international agricultural scientists, policy makers will also find this to be a useful read.

Straminipilous Fungi presents a critical comparative review of the morphology and ultrastructure, morphogenesis, cytology, molecular biology and evolution of the biflagellate fungi. These organisms encompass the fungi formerly called oomycetes; taxonomically related heterotrophs studied by mycologists; plasmodiophorids and other heterotrophs. Appropriate comparisons are made with chromophyte algae, marine heterotrophs and chytridiaceous fungi. Little-known taxa which have been referred to the various orders of flagellate fungi are also listed together with citations. A new hierarchical classification is presented which is supported by systematic accounts and synoptic keys. Dichotomous keys based on habitat and habit are given to all known species of lagenidiaceous fungi, labyrinthulids and plasmodiophorids. A unique `one stop' reference resource for plant pathologists is provided by the binominal lists, including host-related lists for the downy mildews. The book, including ca 4000 references, is a major text for post-graduate and research workers, particularly freshwater and marine biologists, soil ecologists and plant pathologists.
