- Abstract. This paper aimed at explaining the possible effects of climate change on the interaction among environment, plant and pathogen, and proposing possible means for mitigating the effects on plant disease. Based on literature review, it is clear that climate change has direct effects on pathogens, on plant -pathogen interactions, and has indirect effects on microbial interactions. Prolonged periods of environmental conditions (temperature, presipitation and relative humidity) that close to the optimal for the development of the pathogen lead to more severe epidemics. Climate change may directly affect several aspects of the biological of the host plants, including their phenology, sugar and starch contents, nitrogen and phenolic contents, root and shoot biomass, number of size leaves, changes in stomatal densities and conductance and root exudation. Any change of these areas may affect infection and colonization by pathogens. Short -term and long-term changes in the abiotic conditions under which plants are grown may influence not only the growth and the productivity of plants but also the populations of microorganisms living on plant surfaces. Mitigating means for climate ̳s effects can be among the followings: a comprehensive studies on the impact of climate change on the development of plant pests and diseases are needed as to determine appropriate measures which can be adopted by government and farmers. Better understanding by farmers is required as to adjust cultural practices in their farming systems to the climate changes that take place in their localities. Indigenous knowledge which is the bases for arranging the proper planting time in places like Java can be retrieved as traditionally successful pest management. Bio-intensive IPM which optimize the existing bioresources can be applied seriously which require cooperation among goverment, universities, research centers and all components of civil society Keywords: climate change, effects, plant pathogens, plant diseases, mitigation.
