**Abstract**

The change in climate have caused different biotic and abiotic factors to be more prominent when management plan is executed. The increase in temperature have then cause frequent drought that may attract alien species of vectors to spread novel diseases among the native plants. However, the change in climate varies in different countries. Thus, common diseases that threatens food security such as *Xanthomonas spp*., *Pseudomonas spp* are in limelight of research. Vectors lifecycle may cause plant diseases to by cyclative. Therefore, to find the break in the vector's lifecycle will be a method to eradicate harmful population in grassland. Modern days will then call for innovative method and limitations should be considered. Climate change have also impacted pathogens migration and mating pattern. The need for innovative management is constantly on the rise.
