- Reduces nematode egg hatch by an average of 68% while maintaining yield potential
- Provides a biological alternative to chemical nematicides without phytotoxicity or halo effects
Indigo Ag Introduces Next-Generation Bionematicide for Soybeans
Farmers have a new biological solution to manage soybean cyst nematode (SCN): biotrinsic® Nemora FP™, an EPA-registered soybean bionematicide seed treatment from Indigo Ag. Designed to deliver consistent performance without the drawbacks of conventional chemistry, Nemora’s anti-hatch technology helps growers manage nematode pressure while maintaining strong yield potential.
“Nemora is designed to colonize soybean roots and shoots early and persist through the season,” said Jon Giebel, Ph.D., VP North America Commercial–Biologicals at Indigo Ag. “In trials, it delivered improved plant health metrics and compelling yield potential while offering growers a biological option that can benefit soil health in the process.”
Nemora FP™ is formulated as a flowable powder seed treatment for soybeans and is compatible with planter-box applications or Indigo’s CLIPS delivery system. The product contains a naturally occurring Pseudomonas oryzihabitans bacterium that colonizes both roots and shoots. Within weeks, the microbes multiply around the root zone, where they protect the crop and disrupt SCN egg hatching.
How Nemora FP™ Works
Nemora FP™ functions through a multifaceted biological process:
• Stimulates Induced Systemic Resistance (ISR) and forms a biofilm that promotes strong root colonization
• Prevents SCN eggs on roots from hatching, slowing the pest’s lifecycle without harming beneficial nematodes
• Recruits a community of plant growth-promoting bacteria that aid nutrient uptake and root development
The treatment demonstrated:
• 68% average reduction in egg hatch
• Longer taproots, greater root biomass, and whiter roots
• Thicker plant shoots and improved emergence
• No interference with nodulation
• No phytotoxicity or halo effects
“SCN is the nation's most damaging soybean pathogen,” said Dr. Greg Tylka, Morrill Professor, Department of Plant Pathology and Microbiology at Iowa State University. “Soybean farmers in the US and Canada lose many thousands of dollars in individual fields due to reduced yields from the nematode each year. The most sustainable management approach to minimize SCN yield loss is a multi-faceted plan that can include growing nonhost crops in rotation with SCN-resistant soybean varieties and use of nematode-protectant seed treatments on the soybeans.”
Tylka added, “Long-term management of SCN also requires a sustained effort in which success is monitored through periodic soil testing and adjustments in use of management tactics if soil test results indicate changes are warranted.”
Indigo Ag Strengthens Biological Portfolio for Growers
“Nemora is another important tool against the SCN threat and growing resistance to SCN traits like PI 88788,” Giebel added. “As a biological seed treatment, it helps manage nematode pressure by stopping egg hatch and can deliver season-long benefits.”
With Nemora FP™, Indigo Ag continues to expand its biotrinsic® portfolio, bringing sustainable, science-driven solutions to market that empower growers to improve soil health, protect yields, and build resilience against evolving pest pressures.
