Title: Clariant Global Application Development Manager for Crop Solutions

Topic: Tailored Co-Formulants and Adjuvants for Enhancing Stability, Application Properties, and Efficacy of Microbial Biological Formulations

Abstract: 

Microbe-based biological formulations are increasingly adopted as a sustainable tool in agriculture for biocontrol and plant health applications. However, their efficacy is often limited by factors such as reduced microbial viability during storage, insufficient formulation stability, and suboptimal application performance. While a broad range of co-formulants and adjuvants is available to optimize the efficacy, stability, and application properties of conventional chemical crop protection products, comparable formulation solutions for biologicals are still less established. This gap offers significant opportunities to enhance the performance of biological formulations through tailored formulation strategies and innovative adjuvant technologies.

Clariant has developed a dedicated formulator toolbox to address these challenges and improve the performance of biological formulations. The toolbox comprises a carefully selected portfolio of biocompatible dispersants, emulsifiers, and wetting agents designed to improve stability and application properties of solid, aqueous, and oil-based formulations, as well as in-can and tank-mix adjuvants to enhance biological efficacy. The biocompatibility with a broad range of microorganisms, including gram-positive and gram-negative bacteria as well as fungi, has been verified using a fully automated high-throughput viability assay.

For solid WP and WG formulations, which remain the dominant formulation types for microbial products, the wetting and dispersing agents Hostapon TPHC and Dispersogen SI significantly improve wettability and suspensibility. In aqueous bacterial SC formulations, polymeric dispersants such as Dispersogen PSL 100 and Dispersogen PL 40 are valuable options to prevent phase separation during storage and reduce cell agglomeration in the final spray mixture. Emulsogen ELO 200 enables excellent emulsification of vegetable oils, opening new possibilities for oil-based OD biological formulations with improved emulsion stability and blooming behavior. The Synergen Guard product range – innovative nanoemulsions containing natural waxes – can be used both as built-in or tank-mix adjuvants, which boost the performance of foliar-applied biologicals by improving leaf coverage, rainfastness and efficacy. In addition, Synergen Soil represents a novel tool for soil-applied biologicals, that improves moisture distribution in the soil and enhances efficacy. 

Clariant’s comprehensive formulator toolbox demonstrates how tailored formulation and adjuvant technologies can overcome key limitations of microbial biologicals and contribute to more reliable and effective biological crop protection solutions.
