ASTM International Committee E35 on Pesticides and Alternative Control Agents sponsored a symposium in October 2004 addressing pesticide formulations and pesticide delivery systems. This STP is a collection of papers presented at that symposium. The technical papers contained in this STP are divided into three groups: 1) Developments in pesticide formulations, 2) Innovations in adjuvant chemistry, and 3) Advances in application technology research.
The papers addressing developments in pesticide formulations cover the development of a granular pesticide carrier, release rate of the carriers, difficulties encountered in formulating unstable active ingredients in liquid delivery systems, use of de-aromatized fluids in phenoxy herbicides for railroad applications, the use of hydroxy-containing
amides in oil-flowable pesticide formulations, the effect of spray mixture pH on biological efficacy of weak acid herbicides, techniques for overcoming herbicide antagonism, and a technique for evaluating compatibility of pesticides and fertilizers in spray tank mixes.
The papers addressing adjuvant chemistry cover new application for fatty amine alkoxylates, the use of ethylenediamine alkoxylates as a new class of surfactants in glyphosate formulations, the use of trifloxysulfuran with several adjuvants for early detection of herbicide efficacy by visual mortality and chlorophyll fluorescence, evaluation of several adjuvants in efficacy enhancement of tribenuron herbicide, and the effects of formulations containing alkyl glucosides and ethylene oxide-propylene oxide block copolymers on improving the infiltration of water in repellent soils.
The papers covering application technology address the interactions of spray liquid properties (formulation and adjuvant), air temperature, and nozzle performance; nozzle/formulation interactions in terms of rebound characteristics of spray droplets; comparison of field-collected data and the AGDISP model predictions of spray flux in aerial applications to soybeans and cotton; variation of droplet size distribution along the flight line of rotary atomizers; deposition-aid/drift-reducing additives in aerial applications; the effect of pH on emission intensity of fluorescent tracers used in assessment of spray deposition; and an expert system for efficient scheduling of copper sprays in citrus applications.
