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disinfection, spraying, dusting, fumigation, grease banding, wound care, and hand-picking but also scarification, now outdated.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 book is a synthesis and a celebration of a large body of agro-ecological research carried out on the management of the pests of cotton, one of the worlds major crops and one which has historically been a very heavy consumer of inputs of pesticides. It demonstrates how agro-ecological approaches to pest management are at last approaching the mainstream, with an increasing recognition that farmland delivers a wide range of ecosystem services (natures goods and services), including but certainly not solely comprising the production of food.

This book discusses the constraints on biological control ranging from the difficulty of convincing growers that they should infest their crops artificially to the effect of cultural techniques.

The later Middle Ages was an overwhelmingly rural world, with probably three out of four households reliant upon farming for a living. Yet conventional accounts of the period rarely do justice to the variety of ways in which the land was managed and worked. The thirteen essays collected in this volume draw upon the abundant documentary evidence of the period to explore that diversity. In the process they engage with the issue of classification - without which effective generalisation is impossible - and offer a series of solutions to that particularly thorny methodological challenge. Only through systematic and objective classification is it possible to differentiate between and map different field systems, husbandry types, and land-use categories. That, in turn, makes it possible to consider and evaluate the relative roles of soils and topography, institutional structures, and commercialised market demand in shaping farm enterprise both during the period of mounting population before the Black Death and the long era of demographic decline that followed it. What emerges is an agrarian world more commercialised, differentiated, and complex than is usually appreciated, whose institutional and agronomic contours shaped the course of agricultural development for centuries to come.
