Abstract
Poa annua L. is a widespread and persistent weed in managed turfgrass systems, exhibiting both annual and short-lived perennial growth habits. Effective management requires an integrated approach, with chemical herbicides remaining a primary tool. This review outlines the current landscape of chemical control strategies, including pre-emergence and post-emergence herbicide options, plant growth regulators, and emerging chemistries. Herbicide resistance in Poa annua continues to pose a significant challenge, with confirmed cases spanning multiple modes of action. Consequently, sustainable management depends on rotating herbicide classes, using mixtures and sequences of treatments, and integrating nonchemical tactics.
