Expert system application: the smart tools for citrus pest and disease management

Abstract

Expert system technology of the citrus pest and diseases was created by Indonesian Citrus and Subtropical Fruits Research Institute (ICSFRI). This technology was developed to overcome problem with delayed disease monitoring. If the pest attack was not immediately resolved, it would cause more serious damages to the plant and would cause decreasing in the quantity and quality of the citrus yield. In order to anticipate the delay in control, an observation or monitoring carried out during the critical period of the plant was necessary to be done. This technology was in the form of a web-based or android-based program or software application system that was used to monitor citrus pest and disease. The use of this expert system application had been validated in several citrus center areas in Indonesia, i.e. Jember and Banyuwangi, East Java; Sambas - West Kalimantan; Barito Kuala - South Kalimantan and Bangli - Bali. Observation using this application, the data of pest and diseases status at a certain time and location were automatically be recorded in the system and immediately would be known whether or not the control was needed. Thus, the use of this technology as a tool for monitoring citrus pests and disease can be used as a reference for Early Warning System on citrus pest and disease control.
