| dc.description.abstract | This study was conducted by utilizing remote sensing technology in detection, tracking of anthracnose-twister of onion by mapping the geographical distribution of the disease using Geographical Distribution System (GIS). The 11 Barangays of Gabaldon was surveyed and monitored from January to April 2019 by determining the incidence and severity level of anthracnose-twister in onion fields. As the monitoring progresses, Barangay Calabasa with 107.74 hectares was found to have the highest percentageof incidence in 50.04 hectares (48.24%) and the damage ranging from 50.01%-75.00%. Spectrometer and Unmanned Aerial Vehicle (UAV) determined the deviation in the amount of chlorophyll in plant that corresponds to the physical condition of the plant. gabaldon has estimated area of 1,493.46 ha devoted for onion production with an estimated production of 29,869.2 MT. The occurrence and proliferation of the disease was due to favorable environment such as high relative humidity, high wind speed, and low temperature. These factors showed significant roles in the incidence and severity level of the anthracnose-twister in onion fields of Gabaldon, Nueva Ecija. | |
