Research Abstract	We developed a simulation model to estimate the spread dynamics of citrus greening disease (Huanglongbing, HLB) as an example of plant disease diffusion estimation on landscape level. The simulation results suggested that the cooperative control by the neighboring farmers was important to the HLB management. The vector control by the pesticide treatment was considered an effective tool to prevent the HLB spread. In addition, our simulation results suggested that the avoidance of pesticide treatment omission at the small orchard like home garden was important factor for obtaining the enough effect of the chemical control.
