Utilization of remote sensing tools to detect glyphosate drift injury in corn (Zea mays)

With increased usage of glyphosate on transgenic crop varieties, incidences of off-target deposition to sensitive crops has increased dramatically. When glyphosate resistant crops are planted within short distances of non-glyphosate resistant crops, there is an increased likelihood of having crop injury due to glyphosate spray drift. Injury from these events may vary from minimal visual injury to severe losses in crop yield. Assessment of these events is difficult to achieve due to the large areas that may be affected and the natural spatial variability that may be present. The increased availability of remotely sensed data which may account for this spatial variability could result in more accurate assessment of off-target deposition and may allow a better method to predict the effects on crop yield. This research was conducted to determine if remote sensing could be used to assess injury and possible reductions in corn yield associated with a drift occurrence.;Key Words: glyphosate, remote sensing, corn, drift.
