Biologic pre-emergent herbicide with novel mode of action and encapsulation technology
A biologic pre-emergent herbicide that inhibits weed seedling emergence through end product inhibition of natural compounds required for seedling growth. The technology uses an encapsulation agent to enable slow-release delivery, providing 2–4 weeks of weed control without affecting already emerged plants. Validated against Palmer amaranth, annual bluegrass, and ragweed in greenhouse trials.
Overview
This technology is a biologic pre-emergent herbicide with a novel mode of action: it inhibits seedling emergence by blocking the biosynthesis of natural compounds required for early seedling growth. The active biological has demonstrated broad-spectrum activity against both dicot and monocot weed species, including Palmer amaranth, annual bluegrass, and ragweed. Because the active ingredient is a natural product susceptible to breakdown in soil, an encapsulation agent is used to provide slow-release delivery, extending the window of weed control to two to four weeks depending on formulation and delivery method. The herbicide targets only emerging seedlings and does not affect already emerged plants, making it well suited for integration into existing weed management programs.
Technical specifications
- Mode of action: End product inhibition of natural compounds required for seedling growth, validated through chemically complemented dwarf mutants and GC-MS analysis of endogenous compound levels
- Spectrum: Effective against both dicot and monocot species, including Palmer amaranth, annual bluegrass, and ragweed
- Encapsulation: Slow-release encapsulation agent designed to delay breakdown of the active biological in soil and extend the duration of activity
- Performance window: Two to four weeks of complete emergence inhibition in natural soils under greenhouse conditions; longer inhibition observed in agar-based Arabidopsis assays
- Selectivity: No effect on already emerged plants; activity limited to germinating and emerging seedlings
- Validation evidence: Greenhouse trials with natural soils, chemically complemented mutant analysis, and GC-MS quantification of active biological levels in treated seedlings
Technology readiness level
The technology is currently at an early-to-mid stage of development. The active biological has been validated in greenhouse trials against multiple weed species in natural soils, and encapsulation strategies have been demonstrated to extend the duration of activity. Future validation efforts will focus on characterizing the breakdown and soil-availability profile of the active ingredient under greenhouse conditions, assessing dormancy responses across additional weed types, and conducting field testing using standard mixed block experimental designs across multiple soil types. Soil sampling and analytical work will be performed using existing campus facilities to monitor biological agent persistence in the field.
