Herbicidal agent 11

Herbicidal agent 11 (Compound 8a) is a herbicide. This agent exhibits significant post-emergence herbicidal activity against monocotyledonous weed Echinochloa crusgalli, effectively inhibiting its stem and root growth, while maintaining good crop selectivity for wheat, corn, and rapeseed. It also effectively suppresses Digitaria sanguinalis, Eclipta prostrata, and Eleusine indica. Herbicidal agent 11 is suitable for herbicide development.
