    Get 16 technical papers on that fit into the following categories: standards, adjuvant technology, formulation development, spray applications and delivery systems, and seed coatings.

    In the standards section, Doug Currier presented the basics on how to gain OMRI listings for pesticides and adjuvants, including required documentation.

    In the adjuvant technology section, Heuser et al. described the application of polyglycerol esters as benign tank-side adjuvants, and Gargulak et al. detailed the application of ligninsulfonates as green dispersants in fungicidal SC formulations. Penner and Michael presented his results on how dew effects various adjuvants upon the application of glyphosate on post-emergent weeds. Costa et al. evaluated the performance of four crop oil concentrates for drift potential and in field trials to:

    1) determine the efficacy behavior of a fungicide combination; and
    2) determine efficacy control of a three-component herbicide blend.

    In a collaboration between four universities, Zollinger et al. conducted standardized, uniform studies on several weed species known to show glyphosate antagonism with hard water. The goal of the research is to develop an ASTM standard for water conditioning agents.

    In the formulation development section, a new star polymer surfactant was introduced by Kayea et al. with benefits including improved emulsion stability and re-suspension ability as based on evaluations with multiple formulation types and actives.

    In the spray applications and delivery systems papers by Klostermann et al. and Fritz et al. reported on the mode of action of silicone adjuvants as drift control adjuvants and how adjuvants affect high speed aerial applications, respectively. Henry et al. explained how parameters such as nozzle type, pressure and tank mix components influence spray droplet characteristics. Optical image analysis was offered as an alterantive to characterize spray droplet size as compared to the traditional laser method by Sarkar et al.

    In the seed coatings section of papers, Halecky et al. adapted mechanical methods used to predict paint durability in tribological studies with insecticide and fungicide SC formulations. Di Modugno et al. described a new dispersant approach with a polymeric surfactant which allows for an increased active content in the seed coating and reduced dust off.
