Controlled Release Pesticides Formulations

The main goal of this book is to present a summary of the state of the art historical background. Conventional chemical pest control methods are mentioned only as a means of comparison to controlled release. Research endeavour with biological weapons, potential usage of such controls, and the few instances of success are likewise brought into focus with the same motive. Formulations and methods or preparing controlled release pesticides are discussed in some detail as concerns the antifouling and molluscicide areas, where the compounding methodology has been well developed. The mathematical basis of controlled release has been developed to an extent and is presented in an abbreviated form.

This book ​presents an introduction to the concept and need of sustainable agriculture, the mechanisms of conventional and controlled release of pesticides, herbicides and plant hormones. It also contains the carriers which supply controlled release including polymers and nanoparticles. A full chapter is devoted to the theory and simulation aspects.

Highlighting means of reducing toxicity, increasing efficacy, lessening environmental impact, and facilitating product development, this work covers up-to-date advances in pesticide delivery technologies. It evaluates pesticide formulations and their use in mixtures that reduce physical incompatibilities in spray tanks and biological anatagonism in the field.

Pesticide Formulation and Adjuvant Technology brings together experts from industry, academia, regulatory offices, and the legal profession to provide a complete and international reference on agrichemical formulations and modern adjuvant technology. Global specialists discuss key topics, from scientific and technical issues to regulatory and legal aspects, including:

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

Since the middle of the Sixties, new types of formulation for biologically active com pounds have been developed, which have been introduced into the literature under the term Controlled Release Formulations (CRF). Stimulated by results from former and successful pharmaceutical research, which was engaged in the production of prepa rations with protracted effects (introduction onto the market in the year 1952 of D amphetamine in the form of pellets, coated to varying degrees with fats and waxes) 1), experiments were carried out to transfer the prolongation of effectiveness to pesticidal substances also, by means of a depot formulation. Initial work was concerned with the production of protective coatings for sonar systems in marine ecosystems. By means of antifouling paints or rubber coatings containing tri-n-butyl-tin oxide (TBTO), the growth of marine organisms on sonar domes, buoys and hulls in the water could be effectively prevented 2. 3). Controlled release formUlations of pesticides are defined as depot systems which continuously release their toxic constituents into the environment over a specified period of time (usually months to years) 4). According to this definition, such formu lations can be successfully employed where a chronic exposure to biologically active compounds is required over a longer period. The following hypothetical example is intended to illustrate this 5). In Fig. 1, the duration of activity of a non-persistent pesticide with a loss rate under environmental conditions of t1/2 = 15 days, is graphically illustrated.
