　　The economic impact of crop diseases caused by environmental pollution can be complex and go beyond their immediate effect on directly affected agricultural producers.Some of the possible effects are food insecurity,health risk,environmental degradation,increased financial costs,reduced yield of crop food production,and increased production costs.Automatic detection and classification of crop diseases at an early age could help the producers to take corresponding prevention measures in time and ...
