Baucom RS, Iriart V, Soble A, Armstrong MR, Ashman T‐L. 2025. Off‐target drift of the herbicide dicamba disrupts plant–pollinator interactions via novel pathways. New Phytologist 247: 850–862. doi: 10.1111/nph.20438.
In this article, it was reported by the authors that the 1% dicamba‐drift treatment used in the field experiment corresponded to a concentration of 0.083 ml l−1 of Dicamba DMA Salt (Agri Star). Upon reviewing the calculations, the authors determined that the actual solution prepared contained 0.052 ml l−1 of product – c. 0.7% of the field‐application rate (560 g acid‐equivalent ha−1 at 140 l ha−1). This correction does not alter the significance or interpretation of the results presented in this work. This has now been corrected, and the corrected text is shown below.
We apologize for this error.

We applied 0.7% of the field dose (0.7% of 561 g acid equivalent (ae) ha−1) of dicamba (3,6‐dichloro‐2‐methoxybenzoic acid; Albaugh LLC, Ankeny, IA, USA) to plants within five randomly chosen plots and a 0% control to another four plots 4 wk post‐transplantation on 21 July 2021. The 0.7% dicamba treatment represents a particle drift rate (i.e. when herbicide particles travel by wind; Felsot et al., 2011). We applied the field dose to the final two plots (561 g ae ha−1) to ensure the efficacy of the dicamba formulation used. We included ‘Preference’ surfactant (nonionic surfactant blend; WinField Solutions, St Paul, MN, USA) in all treatments (dicamba or control) at 0.1% v/v. Plants were sprayed from one pass until just wet using a handheld multipurpose sprayer (Model #1501HDX; HD Hudson Manufacturing, Lowell, MI, USA) set to a medium‐fine mist with an operating pressure of 40–45 PSI. We used a handheld multipurpose sprayer rather than a CO2 sprayer, which maintains a constant application rate, to simulate the variation that would occur in light of an off‐target drift event in field conditions.
