Biosensor to Detect Isothiocyanates in Plants, Soils, and Seed Meals

Isothiocyanates (ITCs) are bioactive compounds of cruciferous plants that have anti-cancerous properties in humans and are commonly used to control plant pathogens in agriculture by cover cropping, seed meal amendment, or green manuring. Current methods to detect ITCs are time consuming and require specialized training. A novel biosensor detection method for ITCs can be used to analyze soils, plant extracts and solutions to determine the presence and relative level of a variety of different forms of ITCs. In agriculture, assessment of ITCs can inform the efficacy of cruciferous-based practices such as green manuring, validate safe replant dates, and identify cultivars with potentially high ITC production levels.

• Simple easy-to-use method with short hands-on time for analysis
• Adaptable to on-farm use
• Amenable to a variety of media including soil, plant tissue, seed meal, and solutions
• Reduces risk of plant-back damage from Brassicas

• Determine safe plant-back dates after ITC soil biofumigation
• Assess cultivar potentials for ITC production levels
• Confirm ITC production in soil biofumigation, green manuring or cover-cropping
