Mathematical Model for Rice Blast Disease Caused by Spore Dispersion Affected from Climate Factors

Rice blast disease, caused by the fungus Pyricularia oryzae, is one of diseases that reduce rice yields in Thailand. The fungus’s dispersal influences this disease outbreak. This study aims to develop a mathematical model for spore dispersion, namely non-local diffusion equation terms kernel, adding factor causes dispersion due rain splash and adjusting infection term based on weather conditions such as air temperature relative humidity. assessed existence uniqueness solutions Banach’s fixed point theorem used finite difference method solve them. numerical simulation confirmed part analysis. Because climate data was effectively developing pandemic widespread areas.
