L-Phosphinothricin 

L-Phosphinothricin is a glutamine synthetase inhibitor and a non-selective herbicide. L-Phosphinothricin acts as a competitive inhibitor, induces toxic ammonium ion accumulation in plants and bacteria, and indirectly blocks the photosynthesis process. L-Phosphinothricin exerts herbicidal activity against both monocotyledonous and dicotyledonous plant species, is primarily absorbed through plant leaves, exhibits limited translocation in plants, and undergoes rapid degradation by soil microorganisms with no root uptake. L-Phosphinothricin can be used for research on weed control in agricultural and non-crop scenarios^[1].

L-Phosphinothricin (150 g a.i./ha; single post-emergence foliar spray) exhibits time-declining control efficacy against Eleusine indica, with a maximum efficacy of 40% at 7 days after application (DAA) and a reduced efficacy of 10% at 28 DAA^[1].
L-Phosphinothricin (150 g a.i./ha; single post-emergence foliar spray) exerts sustained high control against Brachiaria decumbens with 75% efficacy at 7 DAA and 85% efficacy from 14 to 21 DAA, delivers stable high control of Euphorbia heterophylla with a minimum efficacy of 88.8% across 7 to 28 DAA, and achieves potent control of Borreria verticilata with 90% efficacy at 7 DAA and 80% efficacy at 14 DAA^[1].
L-Phosphinothricin (150 g a.i./ha; foliar spray; single application) applied post-emergence provides minimal control of Lolium species^[1].
