Description: Does cotton seed size influence the risk of injury from soil-applied herbicides? This study conducted in 2012 and 2013 evaluates the impact of various sizes of cotton seed and the resulting injury from PRE applications of diuron at 1 and 2X rates. Plots were rated weekly until 4 WAT and biomass was collected. Statistical separation was achieved using Fisher’s protected LSD at alpha equals .05 in SAS.
