"Everyone is aware of the nineteenth-century Irish potato famine, but fungal diseases of many other crops have had similarly apocalyptic consequences. Today, coffee, cacao, and rubber are threatened by fungi throughout the tropics. Indeed, fungi have carved their way through the ages, attacking every plant that we cultivate, constantly exploiting new hosts. In The Triumph of the Fungi, Nicholas Money offers an intimate picture of these pernicious microbes, the scientists who have sought to control them, and the people directly impacted by the loss of forest trees and cash crops. Even with the development of fungicides and other scientific breakthroughs, fungi continue to be unstoppable - this is the story of their triumph."--BOOK JACKET.
Mediterranean and West European pre-modern agriculture (agriculture before 1600) was by necessity ‘organic agriculture’. Crop protection is part and parcel of this agriculture, with weed control in the forefront. Crop protection is embedded in the medieval agronomy text books but specialised sections do occur. Weeds, insects and diseases are described but identification in modern terms is not easy. The pre-modern ‘Crop Portfolio’ is well filled, certainly in the Mediterranean area. The medieval ‘Pest Portfolio’ differs from the modern one because agriculture then was a Low External Input Agriculture, and because the proportion of cultivated to non-cultivated land was drastically lower than today. The pre-modern ‘Control Portfolio’ is surprisingly rich, both in preventive and interventive measures. Prevention was by risk management, intensive tillage, and careful storage. Intervention was mechanical and chemical. Chemical intervention used natural substances such as sulphur, pitch, and ‘botanicals’. Some fifty plant species are mentioned in a crop protection context. Though application methods look rather modern they are typically low-tech. Among them are seed disinfection, spraying, dusting, fumigation, grease banding, wound care, and hand-picking but also scarification, now outdated. The reality of pest outbreaks and other damages is explored as to frequency, intensity, and extent. Information on the practical use of the recommended treatments is scanty. If applied, their effectiveness remains enigmatic. Three medieval agronomists are at the heart of this book, but historical developments in crop protection from early Punic, Greek, and Roman authors to the first modern author are outlined. The readership of these writers was the privileged class of landowners but hints pointing to the exchange of ideas between them and the common peasant were found. Consideration is given to the pre-modern reasoning in matters of crop protection. Comparison of pre-modern crop protection and its counterpart in modern organic agriculture is difficult because of drastic changes in the relation between crop areas and non-crop areas, and because of the great difference in yield levels then and now, with several associated differences.

This meticulously researched compendium provides every aspect of growing, identifying, harvesting, preserving, and using more than 500 species of herbs. Thorough profiles provide a plant's botanical name and family, whether it is an annual or perennial, its height, hardiness, light requirements, water consumption, required soil type, and pH. The often fascinating history of the plant, the chemistry of its essential oils, and its culinary, landscape, and craft uses are also included, as is advice on how to propagate. For the first edition of their work, both authors received The Gertrude B. Foster Award for Excellence in Herbal Literature from the Herb Society of America. This new edition adds important species and includes updated nomenclature.
