Biological seed treatments
Bayer develops microbial seed treatment formulations combining biological inoculants with chemical crop protection, delivering optimized microbial strains to the seed to enhance nutrient uptake and yield potential by up to 10% on corn.
Overview
Bayer's biological seed treatment program applies selected microbial strains during seed treatment, placing beneficial organisms in direct contact with the emerging root system from day one. Over a decade of research focused on identifying optimal strains and developing formulations that maintain microbial viability when combined with chemical fungicides and insecticides on the same seed. Field testing on corn demonstrates yield improvements of up to 10% when the right combination of chemical and biological treatments is applied.
Technical specifications
- Microbial types: selected bacterial and fungal strains optimized for rhizosphere colonization
- Delivery: applied during seed treatment, co-formulated with chemical fungicides and insecticides
- Compatibility: maintained microbial viability alongside chemical crop protection actives
- Target crops: corn, soybeans (primary); expanding to additional row crops
- Mode of action: enhanced phosphorus and micronutrient uptake via root-zone microbial activity
- Yield response: up to 10% improvement on corn in trials (chemical + biological vs. chemical alone)
- Development: decade-plus research program with ongoing strain selection and formulation optimization
