ABSTRACT

This experiment is intended to develop an image based site-specific method to control redvine in cotton. Three band multispectral imagery was used to establish spectral separability of ground features that may be present in a given field at the time of harvest. Imagery taken just prior to defoliation of the study area was used to delineate areas of redvine infestation. A post harvest site-specific herbicide treatment of dicamba was derived from image products and applied to the study area. Effectiveness of the herbicide treatment will be assessed during the 2003 growing season and appended to this report. Economic analysis of this application will also be pending the 2003 harvest.
