Suspension Concentrates

Suspension Concentrates is a survey into the theory of the formulation and stabilization of suspensions, elaborating on the breaking of aggregates and agglomerates and the role of dispersing agents on flocculation and electrostatic and steric stabilization. Practical analysis by rheology is discussed. Suspension Concentrates is ideal for research scientists and Ph.D. students investigating chemistry, chemical engineering and colloidal science.

Held in October of 2001 in Dallas, Texas, the symposium set out to integrate the efforts of formulation chemists, regulators, and those in industry related to sprayer and nozzle manufacture on topics related to the delivery of crop protection agents (pesticides). Sixteen contributions are presented. After the invited paper on continuity and change in U.S. federal pesticide policy, the papers are organized into two sections, first treating formulation ingredients and design, and then discussing delivery strategies. The first deals with such topics as novel polymeric dispersants, clays as microbial carriers, and Alkyl Citrate Ester surfactants. The second explores such issues as bees as delivery agents, roles of surfactants in foliar application of systemic compounds, and related topics.

This work highlights the physical chemistry of surfactant solutions, detailing a fundamental method of selecting surfactants for agrochemical formulations and delineating how surfactants enhance the biological efficacy of agrochemicals. The unique properties of surfactants that have a major influence on the performance of an agrochemical are summarized.;The book is intended for physical, surface and colloid chemists; biochemists; microbiologists; agronomists; research and development personnel in the pesticide and fertilizer industries; and upper-level undergraduate and graduate students taking chemistry and chemical engineering courses.;College and university bookstores may order five or more copies at a special price which is available on request from Marcel Dekker Inc.

Papers presented at the 13th Symposium on [title], held in Miami, Florida in November 1992. The subjects involve a wide range of disciplines of interest to formulators, basic pesticide manufacturers, applicators, and suppliers to the agrochemical industry. The volume is a compilation of the latest d

Agrochemical products and adjuvants are of vital importance in agriculture, to protect food and fibre crops from weeds, insect pests and diseases, in order to feed and clothe the growing world population. In recent years there have been increasing pressures to produce agrochemical formulations which have a lower environmental impact and are safer in use. Enormous changes have taken place in the chemistry and technology of agrochemicals over the last twenty years or so and this book provides a timely review of the most important area of technology in the development of new products. This book covers issues around international product quality and safety standards and describes the current and likely future trends which will carry the industry forward into the next millennium. It brings together well known international experts with many years of practical experience from agrochemical companies, consultancies, academic institutions and regulatory bodies. Chemists and technologists involved in developing new or improved agrochemical formulations will find this book an essential reference in the course of their work. The book will also be of interest to those working in research and development departments of raw material suppliers, as a concise review of this important field.

The first comprehensive, illustrated guide to vector control methods suitable for use by individuals and communities. Published at a time when large-scale control programs organized by governments are declining, the manual aims to help non-professionals understand the role of vectors in specific diseases and then select and use control methods that are appropriate, effective, affordable, and safe. Hundreds of simple, inexpensive and often ingenious techniques, developed and used in a host of different settings, are presented and described in this abundantly illustrated guide. The manual is intended to assist health workers at district and community level, in aid organizations, in refugee camps, or in resource development projects who do not have direct access to experts in entomology, yet need methods for controlling the vectors of such important diseases as malaria filariasis leishmaniasis schistosomiasis dengue and trypanosomiasis. With this audience in mind, the book combines non-specialist factual information about vectors and the diseases they cause with practical advice on control measures, whether involving the use of insecticides, environmental modifications, or the construction of simple devices from local materials. Details range from a table showing where and when the different groups of biting Diptera are active to a recipe for preparing plaster to protect homes against triatomine bugs, from step-by-step instructions for the construction of cheap insect traps, to advice on how to impregnate bed nets and curtains with suitable insecticides. The book opens with a brief description of recent changes in the approach to vector control, followed by a discussion of factors that can influence the success of control measures undertaken by individuals and communities. The core of the manual consists of eight chapters focused on each of the major vectors and groups of vectors: mosquitos and other biting Diptera; tsetse flies; triatomine bugs; bedbugs, fleas, lice, ticks, and mites; cockroaches; houseflies; cyclops; and freshwater snails. Each chapter includes pertinent facts about the vector's life cycle, behavior, and favorite habitats, the diseases it causes, and their clinical features, including opportunities for prevention, treatment, and control. Against this background, methods for control are presented in great detail. Since the use of control measures is often constrained by lack of resources as well as lack of knowledge, most methods described are simple and cheap, do not require much training or supervision, and are safe for both the user and the environment. The remaining chapters offer guidance on the principles and practice of house spraying with residual insecticides, and provide instructions for the safe use of pesticides and the emergency treatment of poisoning.
