Dicamba drift exposure led to a nearly significant reduction in the total number of flowers produced over the experiment (treatment effect, χ 1 2 = 2.68, P = 0.10; Table S4 ) with S. spinosa, I. hederacea , and D. carota exhibiting significantly fewer flowers in the presence of dicamba (species × treatment effect, χ 8 2 = 6.18, P < 0.001; Table S4 , see Fig.
