Abstract

Rice blast disease is a crucial problem, which can damage the yield of rice products in Thailand. The effects of rice
blast disease tend to severe. To study the outbreak of rice blast disease, we analysed and collected field data to study in
the epidemiology of rice blast disease caused by Pyriculariaoryzae of Khao Dawk Mali 105. The aims of the study are
(1) simulated severity of rice blast disease using the EPIRICE model during 28 July 2015 to 25 June 2016 in
Prachinburi, Thailand, (2) check the accuracy of modelling by comparing the area under disease progress curve
(AUDPC) between simulated and observed data, and evaluate of the model using RMSE and (3) make geographic
severity maps during August to November of 2012-2015 in Ayutthaya, Buriram, Chachoengsao, Chonburi,
Nakhonratchasima, Pathumthani, Prachinburi, and Sakae province. The result from the model can used to explain the
severity of disease epidemiology. In addition, the area where the most outbreaks of blast disease is Buriram province in
2013, with AUDCP value is 20.069 %days.
