Pix® Plant Regulator - Dry Formulation Development

Martin P. Mascianica


The U.S. EPA Office of Pesticide Programs has established objectives for the 1990's to emphasize development of "Reduced Risk Pesticides", to enhance agricultural worker protection, and to focus on pollution prevention. BASF Corporation, basic producer and registrant of Pix® Plant Growth Regulator worldwide, has committed to the development of a third generation of dry Pix® formulations in order to assist the cotton producer in maintaining production efficiency while responding to these regulatory mandates. Three formulations (Pix® DF (35% w:w dry flowable), Pix® SP (98% w:w soluble powder), and Pix® Tablet (98% w:w solid pill type)) have been developed and are in various stages of U.S. registration. These dry formulations offer advantages through: a concentrated source of a.i.; premeasured packets; reductions in total packaging; spill remediation enhancement; and reductions in worker exposure levels. Total weight of formulated product applied per acre can be reduced by 87% (Pix® DF) to 96% (Pix® SP, Pix® Tablet), compared to the Pix® 4.2% liquid formulation. Pix® DF and Pix® SP are packaged in premeasured polyvinyl alcohol (PVA) bags. PVA packaging provides a method to reduce the quantity of packaging in direct contact with the formulation and mixer/loader. Pix® Tablet packaging is similarly efficient. Efficacy testing of each Pix® dry formulation has demonstrated excellent performance and mixing/loading evaluation has proven added efficiencies in handling and clean-up.
