All-natural synergistic formulation to combat fusarium crop diseases

Overview

Fusarium diseases cause significant crop losses worldwide, and growers increasingly need effective, sustainable alternatives to conventional fungicides. This research program is developing an optimized, all-natural formulation (OP) that combines bioactive ingredients from three distinct natural sources—essential oils, lactic acid bacteria, and insect-derived antimicrobial peptides—to create a synergistic biofungicide. The central hypothesis is that carefully selected combinations of natural antifusarium agents will outperform any single ingredient, delivering improved efficacy and safety while providing a proprietary product advantage.

Technical specifications

Source categories being investigated:

• Essential oils (EOs) such as clove and thyme, known for antifungal properties
• Lactic acid bacteria (LAB) including strains such as Lactobacillus coryniformis, which produce bioactive metabolites with antimicrobial activity
• Insect-derived peptides such as silk worm (SW) Cecropins, which are well-characterized antimicrobial compounds

Research approach:

• Each ingredient is screened at multiple concentrations against Fusarium oxysporum to identify active agents
• Combinations of effective ingredients are tested to identify synergistic blends, leveraging the team's expertise in bioactive chemistry including flavonoids and fatty acids
• The most promising combination is refined into an optimized product (OP) formulation

Validation strategy:

• In vitro screening of individual and combined ingredients against F. oxysporum
• Greenhouse trials using wheat grains sown in F. oxysporum-inoculated and control soil
• Treatment groups receive OP or water (control) as a seed soak and as a soil drench every 15 days
• Disease progression parameters are recorded throughout the growing period

Technology readiness level

The project is in the early-to-mid research and development stage. Individual antifusarium ingredients from essential oils, lactic acid bacteria, and insect peptides have prior published support, but the synergistic combination approach is novel for fusarium control. The principal investigator's team has a demonstrated track record applying a similar combination strategy to develop an antiviral spray for chickens, which resulted in a patent for the lead collaborator. Current activities include laboratory screening of ingredients and combinations, with greenhouse efficacy trials planned as the next milestone. Commercial deployment, formulation scale-up, and field-scale validation remain to be completed.
