Seed Transmission and Control of Sclerotinia Sclerotiorum in Soybean Seeds


Book Description

The fourth objective was the seed conditioning as a part of disease management. The fungus was analyzed in relation to the seed size. Seeds that pass through a 10/64 sieve represent the fraction of seeds with the highest incidence of infection. The seed conditioning process (particularly the air screen cleaner) can be very effective in eliminating sclerotia, which represents an important source of inoculum for Sclerotinia sclerotiorum, The fifth objective was to investigate the effectiveness of seed treatment fungicides in eradicating seedborne infection of soybeans with Sclerotinia sclerotiorum. The best results were obtained using carboxim + thiram which reduced the fungus expression by 99% for inoculated seeds, and captan + PCNB + thiabendazole, which reduced the fungus expression by 89% for inoculated seeds.







Principles of Seed Pathology


Book Description

Seed testing centers exist in almost every country in every corner of the globe. More and more students are enrolling in programs that require knowledge of the complex and fascinating science of seed pathology. The implications of seed pathology for human health remains an important issue. For all of these reasons and more, this book is a necessary




Trichoderma


Book Description

Trichoderma is a genus of fungi that are present in all soils, where they are the most prevalent culturable fungi. They are also the most successful biofungicides used in today's agriculture. These green-colored fungi are well known for their antifungal and plant-growth-stimulating effects. This book provides comprehensive information on Trichoderma and its use in medical, agricultural and industrial applications. Section I focuses mainly on identification of Trichoderma species, and Section II is concerned with Trichoderma as a biological control agent. Chapters in these sections cover topics ranging from taxonomic status and biodiversity to biochemical analysis and bio-control application.




Seed-Borne Diseases of Agricultural Crops: Detection, Diagnosis & Management


Book Description

The global population is increasing rapidly, and feeding the ever-increasing population poses a serious challenge for agriculturalists around the world. Seed is a basic and critical input in agriculture to ensure global food security. Roughly 90 percent of the crops grown all over the world are propagated by seed. However, seed can also harbour and spread pathogens, e.g. fungi, bacteria, nematodes, viruses etc., which cause devastating diseases. Seed-borne pathogens represent a major threat to crop establishment and yield. Hence, timely detection and diagnosis is a prerequisite for their effective management. The book "Seed-Borne Diseases of Agricultural Crops: Detection, Diagnosis & Management" addresses key issues related to seed-borne/transmitted diseases in various agricultural crops. Divided into 30 chapters, it offers a comprehensive compilation of papers concerning: the history of seed pathology, importance of seed-borne diseases, seed-borne diseases and quarantine, seed health testing and certification, detection and diagnosis of seed-borne diseases and their phytopathogens, host-parasite interactions during development of seed-borne diseases, diversity of seed-borne pathogens, seed-borne diseases in major agricultural crops, non-parasitic seed disorders, mechanisms of seed transmission and seed infection, storage fungi and mycotoxins, impact of seed-borne diseases on human and animal health, and management options for seed-borne diseases. We wish to thank all of the eminent researchers who contributed valuable chapters to our book, which will be immensely useful for students, researchers, academics, and all those involved in various agro-industries.




Plant-Microbe Interactions and Biological Control


Book Description

Discusses the critical role of host-pathogen interactions in developing new and alternative biocontrol agents that promote plant health and disease resistance in crop pathosystems. Describes state-of-the-art as well as future technologies leading to more effective biological control programs.




Sclerotinia Diseases of Crop Plants: Biology, Ecology and Disease Management


Book Description

The fungus Sclerotinia has always been a fancy and interesting subject of research both for the mycologists and pathologists. More than 250 species of the fungus have been reported in different host plants all over the world that cause heavy economic losses. It was a challenge to discover weak links in the disease cycle to manage Sclerotinia diseases of large number of crops. For researchers and s- dents, it has been a matter of concern, how to access voluminous literature on Sclerotinia scattered in different journals, reviews, proceedings of symposia, workshops, books, abstracts etc. to get a comprehensive picture. With the pub- cation of book on ‘Sclerotinia’, it has now become quite clear that now only three species of Sclerotinia viz. , S. sclerotiorum, S. minor and S. trifoliorum are valid. The authors have made an excellent attempt to compile all the available infor- tion on various aspects of the fungus Sclerotinia. The information generated so far has been presented in different chapters. After introducing the subject various aspects viz. , the diseases, symptomatology, disease assessment, its distribution, economic importance, the pathogen, its taxonomy, nomenclature, reproduction, reproductive structures with fine details, variability, perpetuation, infection and pathogenesis, biochemical, molecular and physiological aspects of host-pathogen interaction, seed infection, disease cycle, epidemiology and forecasting, host resistance with sources of resistance, mechanism of resistance and other mana- ment strategies have been covered.







PCR Troubleshooting and Optimization


Book Description

This book discusses the strategies for preparing effective controls and standards for PCR, when they should be employed and how to interpret the information they provide. It highlights the significance of optimization for efficiency, precision and sensitivity of PCR methodology and provides essential guidance on how to troubleshoot inefficient reactions. Experts in PCR describe design and optimization techniques, discuss the use of appropriate controls, explain the significance of standard curves and explore the principles and strategies required for effective troubleshooting.
