An eye-opening exposé of the struggle to control the world’s seeds and the future of our food Ten thousand years after humans figured out how to stop wandering and plant crops, veteran investigative journalist Mark Schapiro plunges into the struggle already underway for control of seeds, the ground-zero ingredient for our food. Three-quarters of the seed varieties on Earth in 1900 had become extinct by 2015. In Seeds of Resistance, Schapiro takes us onto the frontlines of a struggle over the seeds that remain, one that will determine the long-term security of our food supply in the face of unprecedented climate volatility. Schapiro reveals how more than half of all commercially-traded seeds have fallen under the control of just three multinational agri-chemical companies. At just the time when scientists tell us we need a spectrum of options to respond to climatic changes, thousands of seed varieties are being taken off the market and replaced by the companies’ genetically engineered or crack-baby seeds, addicted to chemical pesticides and herbicides from the day they are planted. Schapiro dives deep into the rapidly growing movement in the United States and around the world to defy these trends and assert autonomy over locally-bred seeds - seeds which are showing high levels of resilience to the onrushing and accelerating impacts of climate change. Schapiro applies his investigative and storytelling skills to this riveting narrative, from the environmentally stressed fields of the American Midwest to the arid fields of Syria, as conditions in the two start to resemble one another, to Native American food cultivators, who are seeing increasing interest in their ability to grow food in shifting conditions over thousands of years; from the financial markets that are turning patented seeds into one of the planet’s most valuable commodities to the fields where they are grown.

The research findings of my M.sc (Plant Pathology) work has been presented in this book. The research was conducted at CCS Haryana Agri. University in Hisar, Haryana, India. The key objectives of the research was to study the effect of the fungus Sclerotium rolfsii on seed germination and seedling vigour of sunflower hybrids and secondly to manage the disease collar rot caused by fungus Sclerotium rolfsii through host resistance, fungicides and bioagents. Sunflower is an oil producing crop and is cultivated all over the world. Sunflower oil is preferred among the consumer's due to its health appeal worlwide. Sclerotium rolfsii Sacc. is a well-known polypagous, ubiquitous, omnivorous and most destructive soil borne pathogen and causes one of the most destructive disease of sunflower worldwide known as collar/stem rot which highly results in yield loss. Therefore, every effort has been taken to study the few key aspects in relation to the pathogen and its effect on sunflower plant growth and yield losses and possible effective ways of managing the fungus to minimize the losses.
Plant pathology embraces all aspects of biological and scientific activity which are concerned with understanding the complex phenomena of diseases in plants. Physiological plant pathology represents those specialities within plant pathology which focus on the physiological and biochemical activities of pathogens and on the response of host plant tissues. Today there is an increasing recognition on the part of the scientific agri cultural community that only through a deeper and more fundamental under standing of all the interacting components of the agricultural biota can we expect to improve our capabilities of feeding an expanding world population. It is in this context that physiological plant pathology has assumed new significance within the broader field of plant pathology. No longer are studies on the biochemistry and physiology of pathogens and pathogenesis merely isolated academic exercises, rather, a substantial coherent body of knowledge is accumulating upon which our understanding of the process of disease developmen t and host resistance is being founded. It is from these foundations of knowledge that ultimately new insights into the control of plant diseases may be expected to grow. It seems appropriate, therefore, that at regular intervals those involved in the various subspecialities encompassing the broadest aspects of physiological plant pathology reassess the contributions within the particular specialities in the light of new knowledge and technologies for the purpose of articulating new and productive directions for the future.
