Lignin microparticles for UV protection and stabilization of herbicides

Overview

Benanova Inc has developed lignin microparticles that provide significant benefits for the agricultural sector by enhancing the stability and UV protection of herbicides. These microparticles are uniform, spherical, and sub-micron in size, which allows them to protect pesticidal actives more effectively. This innovative approach minimizes losses and improves the stability and bioavailability of active ingredients, potentially improving agricultural outcomes and reducing environmental impact without the need for additional EPA registration.

Technical specifications

The microparticles are produced through a proprietary, environmentally friendly process that operates at room temperature and does not require toxic surfactants, solvents, or adjuvants. This process is detailed in US Patent #11,856,848 and is characterized by low energy consumption and scalability. The microparticles' high surface-to-volume ratio is essential for their protective capabilities. Initial tests have shown that these microparticles enhance the performance of synthetic bactericides against pathogens like Xanthomonas perforans. Furthermore, they can prevent herbicide drift, which is a common issue in agriculture.

Technology readiness level

The technology is currently at TRL 5, indicating that it has been validated in relevant environments. Future validation plans include testing the stabilization of various herbicide formulations, assessing UV-absorbent capacities, and performing field tests across multiple sites and seasons. Collaboration with land grant universities will ensure thorough and extensive testing to further advance the technology.
