Novos alvos de herbicidas Mecanismos de crescimento das plantas

GR24 is a synthetic strigolactone analog that tricks parasitic weeds like Striga and Orobanche into germinating prematurely so they die without a host, while also altering plant root architecture. It shows promise for next-generation herbicides and crop improvement, but remains research-only and requires further study on dosage, selectivity, and mechanisms.
