Plant diseases can be caused by several pathogenic microorganisms including fungi, bacteria, viruses, viroids, phytoplasmas and plant parasitic nematodes. In California, several plant pathogens have evolved with native plants and consequently, caused little damage. However, many other pathogens are either not present or have only been newly discovered within the State. Without effective regulations in place, exotic pathogens may gain entry into California from other global regions through imported contaminated plant and soil commodities, and detrimentally impact the State’s agriculture and natural environments.<\/p>\r\n
