Supramolecular agriculture: host-guest chemistry for controlled plant signaling.

Supramolecular host-guest chemistry enables precise control of signaling-molecule delivery, stability, and spatiotemporal release for crop improvement, positioning it as a targeted agrochemical strategy.

• Why it matters: Modern farming relies heavily on chemical inputs, and there is a need for more targeted, efficient ways to manage plant signaling to support sustainable production.
• What they did: The approach uses host-guest supramolecular systems to regulate how signaling molecules are delivered and how long they remain stable, including where and when they are released.
• The result: This framework suggests agrochemicals can be transformed into targeted, efficient tools for sustainable farming by improving control over plant signaling.
