Smart farming: modeling distribution of Xanthomonas campestris pv. oryzae as a leaf blight-causing bacteria in rice plants

Abstract

Abstract Regarding plant protection in agriculture, it has been known that the cause of leaf blight is the bacteria named Xanthomonas campestris pv. oryzae. This paper aims to conduct a species distribution model of leaf blight-causing bacteria in rice plants and elaborates on its habitat suitability throughout Indonesia within the climate change context. The occurrences data was extracted from the Global Biodiversity Information Facility (GBIF), whereas the climate data was obtained from the Worldclim data set. The Species Distribution Model used the Maximum entropy method available on the Ecocommons website. The result shows that the bacteria occurrences positively correlate with several climatic variables and spread throughout the archipelago presented into five classes. Main islands such as Java, Bali, and Sumatra share areas with the highest suitability values. While Kalimantan and Sulawesi only share small areas with high suitability area. Papua has a less suitable location for the bacteria to spread. Rice cultivation is inseparable from the threat of pests and diseases. It can cause losses in the form of decreased production to crop failure. Therefore, The Species Distribution Model needed to identify areas where the vector is likely to occur. This way, mitigation or even prevention efforts could be made effectively.
