Relationship between Cotton Reflectance Data and Visual Injury Ratings of Varied Rates of 2,4-D and Dicamba

Various rates of 2,4-D and dicamba were applied to dicamba-tolerant and 2,4-D tolerant cotton, respectively at pinhead square and two weeks after first bloom.  Visual injury ratings will be compared to reflectance data collected from multispectral sensors to determine if a relationship is present between the two.  Cotton response to rates of 2,4-D and dicamba will also be measured in terms of growth, maturity, and yield.
