For many years, much of the human population has lived in ignorance of plant disease - yet the presence or absence of disease in a crop, or a forest, can mean the difference between economic success or disaster, and - even in the 21st century - the difference between life and death for millions of people. This primer raises the profile of plant infectious diseases, highlighting the scale of the problem, the risks to biosecurity, and the advances in science which are impacting on surveillance, diagnosis and prevention of disease. This text opens with an overview of the importance of plant disease in human history, before reviewing the structure and function of the main types of pathogens involved in plant infectious diseases (bacteria, viruses, fungi and fungi-like pathogens), focusing on unusual and interesting examples. It then explores how plant diseases can be accurately diagnosed, explaining a variety of ways in which specific pathogens can be identified including the most recent developments in molecular analysis as well as cultural and serological techniques. The primer then moves on to consider disease surveillance, which still relies heavily on traditional techniques based on human observation. It also considers emerging techniques involving epidemiological models, remote monitoring, the monitoring of air and water, satellite tracking and genetic modification of crops. Disease management - ways in which plant diseases can be controlled and their spread halted - is then discussed. This area encompasses techniques spanning chemical control of insect, fungal and bacterial pests to genetic modification of crops to introduce disease resistance. The final section of the primer explores plant biosecurity and how it can be maintained - an ever-more important issue given the continued globalisation of trade - and the impact of global warming on where both plants and plant pathogens can grow and thrive.

The Day Freedom Died: The Colfax Massacre, the Supreme Court, and the Betrayal of Reconstruction

The untold story of the slaying of a Southern town’s ex-slaves and a white lawyer’s historic battle to bring the perpretators to justice Following the Civil War, Colfax, Louisiana, was a town, like many, where African Americans and whites mingled uneasily. But on April 13, 1873, a small army of white ex–Confederate soldiers, enraged after attempts by freedmen to assert their new rights, killed more than sixty African Americans who had occupied a courthouse. With skill and tenacity, The Washington Post’s Charles Lane transforms this nearly forgotten incident into a riveting historical saga. Seeking justice for the slain, one brave U.S. attorney, James Beckwith, risked his life and career to investigate and punish the perpetrators—but they all went free. What followed was a series of courtroom dramas that culminated at the Supreme Court, where the justices’ verdict compromised the victories of the Civil War and left Southern blacks at the mercy of violent whites for generations. The Day Freedom Died is an electrifying piece of historical detective work that captures a gallery of characters from presidents to townspeople, and re-creates the bloody days of Reconstruction, when the often brutal struggle for equality moved from the battlefield into communities across the nation.
