Widmer, T. L. 2015. Differences in virulence and sporulation of Phytophthora kernoviae isolates originating from two distinct geographical regions. Plant Dis. 99:460-466.Phytophthora kernoviae has only been isolated from the United King dom and New Zealand. To understand what differences may exist be tween isolates from these two distinct geographical regions, virulence studies on three host plants and sporulation on host leaves were con ducted on select isolates. Three host plant species (Rhododendron ponticum. Magnolia stellata, and Annona cherimola) were inoculated individually with sporangia of six different isolates from each geograph ical region. Results showed an overall higher virulence on all three hosts from isolates originating from the United Kingdom. After inoculation, P. kernoviae sporangia and oospore formation on different host leaves were observed and compared with P. cactorum and P. syringae. Results were host dependent, with P. kernoviae producing generally similar or higher amounts of both propagules compared with the other U.S. indig enous species. These results have implications for regulatory agencies and scientists who are interested in preventing its entrance into the United States and learning more about its potential spread.Movement and introductions of crops and plants into a new area has the potential to both move exotic pathogens into that area and expose new hosts to previously noncharacterized indigenous plant pathogens.

Interceptions of Nonindigenous Plant Pests at US Ports of Entry and Border Crossings Over a 17-year Period

et al. 2006

Despite the substantial impacts of nonindigenous plant pests and weeds, relatively little is known about the pathways by which these organisms arrive in the U.S. One source of such information is the Port Information Network (PIN) database, maintained by the U.S. Department of Agriculture, Animal and Plant Health Inspection Service (APHIS) since 1984. The PIN database is comprised of records of pests intercepted by APHIS personnel during inspections of travelers' baggage, cargo, conveyances and related items arriving at U.S. ports of entry and border crossings. Each record typically includes the taxonomic identify of the pest, its country of origin, and information related to the commodity and interception site. We summarized more than 725,000 pest interceptions recorded in PIN from 1984 to 2000 to examine origins, interception sites and modes of transport for nonindigenous insects, mites, mollusks, nematodes, plant pathogens and weeds. Roughly 62% of intercepted pests were associated with baggage, 30% were associated with cargo and 7% were associated with plant propagative material. Pest interceptions occurred most commonly at airports (73%), U.S.-Mexico land border crossings (13%) and marine ports (9%). Insects dominated the database, comprising 73 to 84% of the records annually, with the orders Homoptera, Lepidoptera and Diptera collectively accounting for over 75% of the insect records. Plant pathogens, weeds and mollusks accounted for 13, 7 and 1.5% of all pest records, respectively, while mites and nematodes comprised less than 1% of the records. Pests were intercepted from at least 259 different locations. Common origins included Mexico, Central and South American countries, the Caribbean and Asia. Within specific commodity pathways, richness of the pest taxa generally increased linearly with the number of interceptions. Application of PIN data for statistically robust predictions is limited by nonrandom sampling protocols, but the data provide a valuable historical record of the array of nonindigenous organisms transported to the U.S. through international trade and travel.

“…Through coordinated efforts with government institutions, Colombia successfully delayed the pathogen's arrival into national plantations until September 1983, positioning itself as one of the last countries in the region to confront the disease [8]. Exclusion may involve one or a combination of the following actions [18,[20][21][22]: a.…”

Integrated Disease Management for the Sustainable Production of Colombian Coffee

Coffee stands as a vital pillar of Colombia’s economic prosperity, constituting approximately 7% of the nation’s agricultural GDP. Moreover, it serves as a significant contributor to national agricultural employment, with direct jobs stemming from coffee cultivation comprising 26% of the total agricultural workforce. This underscores the pivotal role coffee plays in shaping Colombia’s social and economic landscape, solidifying its position as the primary origin of mildly washed coffees for global consumers. However, Colombia’s coffee production grapples with the challenge of operating amidst persistently rainy conditions, fostering an environment conducive to fungal diseases. This, compounded by environmental, economic, commercial, and safety constraints for disease control, creates a multifaceted scenario that continuously tests disease management strategies. Addressing this complex dynamic demands a crop protection framework that seamlessly integrates efficient and sustainable methodologies. Such methodologies should prioritize outbreak prevention, cost-effectiveness, adherence to national and international regulations, and the preservation of environmental and human health. Integrated disease management emerges as a solution capable of optimizing productivity tailored to the unique conditions of each plot. By mitigating the impact of pathogens while responsibly utilizing and conserving natural resources, this approach safeguards the well-being of both producers and consumers alike.
