Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.
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.
Fungicides, Volume I: Agricultural and Industrial Applications, Environmental Interactions discusses the application, use, and environmental interactions of fungicides. This book is organized into 15 chapters that cover the commercial development of fungicide and the organism's interaction with the environment. After discussing the history of fungicides, the book presents data on world fungicide usage and how this usage is influenced by epidemiology. It then describes procedures and approaches for commercial fungicide development; practical tests and laboratory techniques for agricultural fungicide toxicity; and significance of fungicide formulation that is determined by a variety of factors, including cost and biological efficiency. The following chapters discuss technological evolution, both in chemical fungicides and in the machinery for their application for soil and seed treatment. The application of foliar and postharvest fungicides and the use of other fungicides as industrial and wood preservatives is also tackled. The last four chapters are concerned with the various interactions between fungicides and the environment which may cause them to be more or less effective. The book will be useful to researchers, advanced students, and professional workers in the fungicide field of study who are concerned with the synthesis and development of better fungicides or their mode of action.
