The purpose of the studies was to determine the potential of utilizing video imagery technology in kenaf production. Results indicated that video imagery had good potential for detecting plant stress caused by Phymatotrichum root rot and the root-knot nematode/soil-borne fungi complex. Imagery from the three years indicated that remote sensing technology can provide an effective method for the detection and seasonal monitoring of plant injury and disease migration in kenaf production. Airborne video imagery should also be a rapid means of detecting problematic areas in large-scale plantings of kenaf. The detection of these problematic field areas would be very beneficial to producers for determining optimum harvest dates and for future planting site selection. Technical Abstract: Kenaf (hibiscus cannabinus L.)is one of several annually, renewable nonwood fiber crops that is grown in the world. The tall plant growth habit of kenaf and the high plant densities used in commercial production can make detection of plant injury and crop stress very difficult. Since airborne video imagery has been used to detect plant injury in several crop species, ,the potential of utilizing this technology in kenaf production was evaluated at three experimental locations. Results indicated that video imagery had good potential for detecting plant stress caused by Phymatotrichum root rot and the root-knot nematode/soil-borne fungi complex. Imagery from the three locations indicated that remote sensing technology can offer an effective method for the detection and seasonal monitoring of plant injury and disease movement in kenaf production. Airborne video imagery should also be a rapid means of detecting problematic areas in large-scale plantings of kenaf. The identification of these problematic field areas would be very beneficial to producers in regards to determining optimum harvest dates and for selecting the location of future planting sites. |
