Technical Abstract: Cotton root rot has affected cotton production in the southwestern and south central U.S for over 100 years. A fungicide, flutriafol, has shown considerable promise for controlling this disease in field studies in the last few years. With the temporary authorization for use of the fungicide to control cotton root rot for 2012 and 2013 in Texas (Section 18 exemption), many cotton growers have used this product to treat their fields that have been historically infected with the disease. The objective of this study was to use airborne multispectral imagery to monitor the progression of cotton root rot infection in cotton fields treated with this fungicide. Airborne multispectral imagery with blue, green, red and near-infrared bands was taken from a number of treated fields near Corpus Christi and San Angelo, TX multiple times during the growing season in 2012. In this presentation, images taken from selected fields were used to illustrate the progression of cotton root rot and the efficacy of the treatments under treated conditions as compared with images taken under non-treated conditions in previous years.
