Pesticide Formulations and Delivery Systems
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.

Weed Biology and Management
Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and b...
