Biocontrol Technology Launched by NewLeaf Symbiotics

NewLeaf Symbiotics has introduced TS201, an EPA-registered biocontrol technology aimed at repelling Corn Rootworm (CRW) and protecting corn roots. This technology introduces a new mode of action for controlling rootworm, by using the plant’s own defenses to produce a compound that repels larvae at the root. TS201 is designed to work alongside existing crop protection and trait strategies while being effective in repelling CRW and enhancing root mass.

According to Brent Smith, the CEO and president of NewLeaf Symbiotics, protecting corn varieties from CRW has become increasingly challenging for farmers due to the rise of Bt-resistant variants that outlast crop rotation. As farmers prepare for the upcoming planting season, TS201 offers a new research-proven solution to help them combat this threat.

Field trials of TS201 have shown that it leads to significant crop retention, increased yield, reduced lodging, and an improvement in root density. Compared to standard root growth, TS201 technology resulted in 9% more fine roots, 16% greater root surface area, and 10% deeper roots, indicating healthier plant growth and better nutrient uptake.

Dr. Natalie Breakfield, the vice president of Research and Discovery at NewLeaf Symbiotics, explained that when TS201 is applied, the plant’s immune system is primed, leading to better growth through improved nutrient and water uptake, and reduced lodging compared to insecticide or traited management alone. This is especially important during a year when growers are facing significant financial pressures, underscoring the need for an effective CRW defense plan to ensure optimal yield results.

TS201 technology is currently available through partnerships with Meristem Crop Performance, Low Mu Tech, and AMVAC. In addition to TS201, NewLeaf Symbiotics also offers biostimulant technologies for corn, soy, cotton, and peanuts. This provides farmers with a range of tools to enhance the health and productivity of their crops while protecting them from pests like CRW.
