90 SEEDWORLD.COM DECEMBER 2015 causes bacterial spot of tomato and pepper plants. International trade in seeds is likely affecting distri- bution of all four bacterial spot species Goss and the research team reported in the February 2015 edition of the journal Applied and Environmental Microbiology. It is notable that in Ethiopia Nigeria Tanzania and the SWIO islands three or more different species are found within tomato-growing regions whereas in the United States there appears to be a single dominant species in each region. Goss says the presence of multiple species might be due to the import of seeds or plant material from multiple sources a hypothesis that needs to be tested. Climate Change and Pathogen Movement Rising annual mean temperatures are changing the global climate with significant effects on people and the environments they inhabit. Climatologists report that the increasing severity of weather will continue into the foreseeable future. The U.S. Department of Agriculture USDA states in a report entitled Climate Change and Agriculture Effects and Adaptation that while U.S. agriculture and resource management have long histories of success- ful adaptation to climate variability the accelerating pace and intensity of climate change presents new challenges. USDA reports that climate change will exacerbate the stresses already occurring from insects and disease. Increases in the inci- dence of extreme weather events will have an increasing influence on agricultural productivity. During the next 25 years USDA adds the effects of climate change on agricultural production and economic outcomes for both pro- ducers and consumers in the U.S. are expected to be mixed depend- ing on regional conditions. Beyond 2050 changes are expected to include shifts in crop production areas increases in pest control expenses and greater disease prevalence. While tourists and commercial plant imports from around the world have the potential to carry pathogens to the U.S. from other countries hurricanes add to the problem as wind-borne pathogens can appear or reappear from the Caribbean and Latin America. Differences in weather pat- terns can make pathogens more prevalent says Jeffrey Jones. If you have more storms with lots of New virulent varieties of pests emergence is favored by increased sizes of pest populations and their rapid life cycles Hope lies in the implementation of robust plant protection strategies and biosecurity measures particularly in the developing world.
