Formulation Solutions for Biopesticides
Through the use of living microorganisms, natural substances, or semiochemicals, biopesticides prevent or reduce damage from pests, weeds, and pathogens, emerging as one of the most promising tools to empower a sustainable future of agriculture.
The biopesticides market continues to grow, finding its way into integrated pest management (IPM) practices, as it helps reduce the risk of resistance to synthetic agrochemical actives. Increased adoption of biopesticides is also a way for the agricultural market to respond to looming consumer demands on organic and residue-free food. This rise in environmentally aware consumers and increasingly stringent regulatory requirements continue to drive the agriculture market shift from synthetic conventional pesticides to biological pest control.
European Union’s Farm to Fork strategy and the Brazil National Bio-Input Program clearly set targets to favor this transition towards mitigation of conventional agrochemicals usage.
However, the global rate of adoption of Biocontrol-based solutions remains low in comparison with conventional pesticides, with less consistent biological efficacy observed in the field, in adverse conditions. Classical root causes analysis include lack of stability of the product during storage, less active material reaching the target and rapid degradation of the biopesticide once applied related to environmental factors. Optimized formulation strategies are a key lever to enhance global bioefficacy of such biopesticides.

Challenges of Microbial Biopesticides in Agriculture
Each beneficial microorganism species has different sensitivities to chemicals, temperature, environmental factors such as UV, drought, and humidity. Additionally, even through a similar microorganism category, the strains and fermentation processes have a substantial impact on final broth composition, impacting formulation methodology and biological performance.
Microbial Biocontrol Key Challenges
- Shelf Life and Storage
- Application Handling and Delivery
- On-target Viability and Bioefficacy
The Role of Formulation in Microbial Biopesticide Efficacy
Formulation plays a key role in overcoming the challenges facing the agricultural market as it transitions towards producing microbial biocontrols with enhanced efficacy. Adequate co-formulant selection is vital to the outcome as it can lead to:
- Optimal shelf life, with enhanced microorganisms viability
- Satisfactory wetting & homogeneous dispersion upon formulation dilution for enhanced on-target application of the microorganisms
- Spray droplet size control for optimal coverage (foliar & soil)
- Improved wetting, adhesion, humectancy, and rainfastness on target
- Improved viability of microorganism on target (seed)
- Increased microbial activity against targeted pests and pathogens
Thanks to our extensive experience in agrochemical formulation, microbiology, and phys-chem, Solvay is able to offer a unique culmination of resources, facilities, and expertise to deliver unrivaled agrochemical and biopesticide formulation solutions. We offer a range of ingredients for microbial biopesticide solutions for foliar, soil, and seed applications.
