Fig.1. Overview of potential climate, [CO2] and their interactions on herbicidal control of agricultural weeds before, during and after herbicide application. Before: climate- or
[CO2]-induced changes in weed species populations, and [CO2]-induced selection of weeds over crops will influence timing and herbicide selection; During: Variation and
long-term trends in wind, temperature and precipitation can influence efficacy of spray patterns and herbicide retention times following spraying; After: Climate or [CO2] can
have long-term physiological effects, such as reducing protein levels, that could potentially reduce herbicidal mode of action.
