  • Nouryon: Formulation of Agrochemicals in High Electrolyte Systems  

    2019-06-03

    The need to incorporate agricultural actives (ais) in high electrolyte systems such as fertilizers for in-furrow applications, or in tank mixes for spray applications, provides a significant challenge to the formulator. Many ais have poor water solubility and are often formulated in suspension concentrates (SCs). However, the addition of SCs to a starter fertilizer such as 10-34-0 will often result in a rapid flocculation of the system. This is clearly undesirable; farmers require a system that is sufficiently stable to allow them time to complete their application without the risk of blocked nozzles or uneven application.
