Low herbicide doses can change the responses of weeds to subsequent treatments in the next generation: metamitron exposed PSII‐target‐site resistant Chenopodium album as a case study

open access: yesPest Management Science, Volume 76, Issue 9, Page 3056-3065, September 2020., 2020
Abstract BACKGROUND It is well known that exposure to mild stress can precondition organisms to better tolerate subsequent stress exposure in the same or future generations. Since herbicide hormesis also represents a moderate stress to exposed plants, a transgenerational priming is likely but not proven.
