Goals / Objectives
The overall goal of the project is to contribute safeguarding U.S. agricultural crops and natural plant resources against introduced and endemic pathogens and pests. The Northeast region of NPDN, comprised of representatives of Land Grant Universities and Agricultural Experiment Stations from twelve northeastern states, forms a cohesive team of diagnostic specialists who are skilled at rapid and accurate identification of plant pests and pathogens of consequence. With the current proposal, we will ensure that service provided by NEPDN is of the highest quality to (1) make accurate diagnoses to experts in the Network while upgrading training of diagnosticians with modules that use contemporary, interactive technology to achieve educational goals, (2) submit all diagnoses and identifications to the National Repository, (3) maintain and develop strong working relationships and communications with appropriate state and federal regulatory agencies, while implementing a governance structure that ensures fair and equitable representation by all who have a stake in the mission of the Network, and (4) lead and support a network-wide STAR-D laboratory accreditation system through the Northeast Regional Hub. In addition, the Northeast Regional Hub continues to represent NPDN in a collaborative effort with the American Public Gardens Association and to expand a Sentinel Plan Network.
Project Methods
Plant samples will be diagnosed and test results will be submitted to the National Repository. Training ofdiagnosticians will be coordinated with USDA-APHIS. First detector training will be coordinated with NPDN and the Sentinel Plant Network in conjunction with the American Public Garden Association. STAR-D training and accreditation will be managed by NEPDN.

Outputs
Target Audience:Target audiences reached by NEPDN efforts were primarily growers, extension educators, IPM specialists, master gardeners, homeowner's, State Departments of Agriculture, Departments of Environmental Conservation, American Public Gardens Association, USDA-APHIS-PPQ, State Plant Health Directors, State Plant Regulatory Officials and fellow diagnosticians within the National Plant Diagnostic Network. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Due to restrictions related to the covid19 pandemic, less opportunities for training and professional development were provided during this reporting period compared to previous reporting periods. However, more virtual training and professional development opportunities were provided online. Presentations were made at short courses, webinars and videoconferences. In addition, results were delivered via fact sheets, newsletters, journal articles, and book chapters. How have the results been disseminated to communities of interest?Diagnostic results were disseminated to growers, extension educators, IPM specialists, master gardeners, homeowners, members of the American Public Gardens Association, and fellow diagnosticians within the National Plant Diagnostic Network State. Information was also shared with Departments of Agriculture, Departments of Environmental Conservation, USDA-APHIS-PPQ, State Plant Health Directors, and State Plant Regulatory Officials. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Outputs
Target Audience:Target audiences reached by NEPDN efforts were primarily growers, extension educators, IPM specialists, master gardeners, homeowners, Departments of Agriculture, Departments of Environmental Conservation, American Public Gardens Association, USDA-APHIS-PPQ, State Plant Health Directors, State Plant Regulatory Officials and fellow diagnosticians within the National Plant Diagnostic Network. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?The NEPDN Regional Center had 2 members who obtained Phytophthora ramorum (SOD) certification in 2019 via NPPLAP certification through APHIS-PPQ Science & Technology. Additionally, NEPDN members have attended NPDN and USDA-APHIS-PPQ-Science & Technology, Beltsville Laboratory sponsored training sessions of significant pathogens. These molecular and morphological identification techniques that diagnosticians feel are necessary to stay prepared for significant introductions, have continued only because of supplemental funding procured by the NEPDN Regional Center staff and made available for all NPDN diagnosticians. Snover-Clift pursued the funding support for this national activity and was rewarded with funding through the Farm Bill. She worked with USDA-APHIS-PPQ to again coordinate NPDN members attending the workshops conducted by USDA-APHIS experts at the federal laboratory in Beltsville, Maryland. For 2020, ten workshops for 72 participants were planned but due to COVID-19 restrictions developing in mid-March, six workshops were postponed. Four workshops were held; Bioinformatics module SS, Bioinformatics module HTS, Seed Testing (CGMMV) and Isothermal Amplification. The workshops postponed were second offerings of Bioinformatics module SS, Bioinformatics module HTS, Seed Testing (CGMMV) and Isothermal Amplification and a workshop on Phytopthora species and Monilinia, a new topic for 2020. Three members from the NEPDN attended two workshops this year. The NEPDN regional participants that attended the 2020 Beltsville Workshops included Ekaterina Nikolaeva and Kiersten Bushong from the Pennsylvania Department of Agriculture and Rachel Ross from the University of Maryland. Those that had planned to attend postponed workshops were, Abby Beissinger of the University of Connecticut, Alicyn Smart and Tom Rounsville of the University of Maine, Tammy Jones and Rachel Knier of the Pennsylvania Department of Agriculture (planned to attend two workshops offered in the same week), Karen Snover-Clift and Sandra Jensen of Cornell University. NEPDN diagnosticians attended a total of 157 professional development training sessions on a variety of topics that included molecular techniques, invasive species, CAPS surveys and new and significant insect pests and The NEPDN diagnosticians provide numerous trainings for extension educators, growers, Master Gardeners, and other diagnosticians. How have the results been disseminated to communities of interest?NEPDN member states directly benefit from the professional development of our region's diagnosticians. Dissemination to communities of interest is often done through outreach educational opportunities, through the lab's webpages and social media, extension newsletters and other news venues and at plant professional and grower meetings. Additionally, diagnosticians provide tailored one on one, direct contact through phone calls, emails and sample result reporting to our clientele. These individual teaching moments provide a wealth of information to our clientele. NEPDN members produced 211 publications and 398 products/presentations with 17,443 attending participants during the time period of this report. NEPDN members have presented and published material focusing on general plant pathology; diagnosing plant problems; master gardener diagnostics and hot topics; the NPDN, NEPDN, SPN and STAR-D; specific pest and plant disease issues, general pest problems, tree diseases, invasive species; as well as general pathogen information such as bacterial, fungal, viral and nematode pathogens; and abiotic issues such as cultural practices, effects of drought conditions on trees and shrubs, climate change; and the select and significant agents specifically targeted by USDA-APHIS. Attendees include individuals from grower organizations, arborists, agricultural inspectors, IPM specialists, golf course managers, crop consultants, master gardeners, first detectors, horticultural society members, pesticide applicators and other plant pathologists and entomologists. What do you plan to do during the next reporting period to accomplish the goals?1. Diagnostics: Submission of all plant pathology laboratory data will continue using the PDIS database sample management system. Data submission is required for member laboratories in the NPDN. The NEPDN staff will continue to encourage diagnosticians to attend trainings they feel is needed to expand their knowledge of plant pathogens or diagnostic techniques, will continue to assist the NEPDN members were needed with advanced testing procedures or for coverage during periods of time when they will be away from their home base (to attend trainings or for other activities) and will continue to hold annual meetings to ensure communication lines are maintained and sharing of information is common. The NEPDN staff will coordinate sample movement and surge, and provide all updated SOPs and protocols on a timely basis as needed. NEPDN members and the NEPDN Associate Director will update and/or author new SOPs as needed and will continue to provide a leadership role in the diagnostics, national database and strategic planning areas of professional development and lab accreditation. The WPDN will lead efforts for planning the next national NPDN meeting in the spring 2021. If offered, Snover-Clift will coordinate a regional meeting and training activities for the NEPDN diagnosticians. Rachel McCarthy, a member of the Communications Working Group, will continue to provide support on a part-time basis and for a very limited time by coordinating updates and information technology issues associated with the NPDN Training and Education website (www.firstdetector.org).

Impacts
What was accomplished under these goals? NEPDN members processed over 16,471 samples, with more than 99 detections being first reports in their state. The types of organisms detected included 6,169 pathogens, 2,104 arthropods, 600 plants/ weeds, 2,178 nematodes, 2,617 abiotic disorders, and 2,311 other. NEPDN member laboratories have the capability to assist with surge samples by receiving 1,075 extra Phytophthora sp/spp. and P. ramorum samples, 500 extra PPV samples, 100 extra Phytoplasma samples, 50 extra golden nematode samples, 300 extra oak wilt samples, 300 extra Dutch elm disease and 300 extra boxwood blight samples. Additionally the NEPDN Regional Center is prepared to provide surge for an additional 500 HLB samples, 500 Phytophthora ramorum samples, 200 potato cyst and soybean cyst nematode samples, 500 extra PPV samples, 500 Ralstonia spp. samples, 500 soybean rust samples, 200 thousand cankers samples and 400 additional oak wilt samples. Additionally, the NEPDN regional hub lab retained STAR-D Accreditation and NPPLAP Certification for processing Phytophthora ramorum samples for anyone in the continental United States. In 2019, the NEPDN Regional Center processed 234 NPPLAP samples with the majority coming from positive nurseries across the country. NEPDN members are have a significant role in providing outreach and presented and published material focusing on general plant pathology; diagnosing plant problems; specific pest and plant disease issues, invasive species, how climate change affect pathogens and pests and the select and significant agents specifically targeted by USDA-APHIS. NEPDN members produced 211 publications and 398 products/ presentations with 17,443 attending participants during the time period of this report. NEPDN members attended 157 professional development workshops on topics such as STAR-D and quality management, the American Phytopathological Society national and divisional meetings, diagnostic workshops on morphological and molecular identification of pathogens, biosecurity training, invasive species workshops, extension and grower meetings National Plant Board and Cooperative Agriculture Pest Survey (CAPS) meetings.

Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Training and professional development activities such as the Beltsville workshops, STAR-D accreditation and 1st detector workshops through the Sentinal Plant Network are continued to be offered. NEPDN members attended 94 professional development workshops on topics such as STAR-D and quality management, the American Phytopathological Society national and divisional meetings, diagnostic workshops on morphological and molecular identification of pathogens, biosecurity training, invasive species workshops, extension and grower meetings National Plant Board and Cooperative Agriculture Pest Survey (CAPS) meetings. How have the results been disseminated to communities of interest?NEPDN members have a significant role in providing outreach and presented and published material focusing on general plant pathology; diagnosing plant problems; specific pest and plant disease issues, invasive species, how climate change affect pathogens and pests and the select and significant agents specifically targeted by USDA-APHIS. NEPDN members produced 124 publications and 535 products/ presentations with 28,946 attending participants during the time period of this report. What do you plan to do during the next reporting period to accomplish the goals?For the next reporting period, we are planning on expanding on current activities such as diagnoses, submissions to the national repository, and training and professional development activities such as the Beltsville workshops, a new laboratory accreditation in conjunction with the NPDN Executive Committee, and SPN workshops.

Impacts
What was accomplished under these goals? Diagnoses are continued to be made by every laboratory of the NEPDN using various technologies. Diagnoses are regularly submitted to the NPDN national repository. Opportunities to foster professional development activities such as the Beltsville workshops and STAR-D accreditation are furthered; so are workshops offered by the Sentinal Plant Network (SPN). NEPDN members processed over 16,550 samples, with more than 80 detections being first reports in their state. The types of organisms detected included 7,884 pathogens, 2,541 arthropods, 679 plants/weeds, 463 nematodes, 2,826 abiotic disorders, and 2,310 others. NEPDN member laboratories have the capability to assist with surge samples by receiving 1,075 extra Phytophthora sp/spp. and P. ramorum samples, 500 extra PPV samples, 100 extra Phytoplasma samples, 50 extra golden nematode samples, 300 extra oak wilt samples, 300 extra Dutch elm disease and 300 extra boxwood blight samples. Additionally, the NEPDN regional hub lab retained STAR-D Accreditation and NPPLAP Certification for processing Phytophthora ramorum samples for anyone in the continental United States. In 2018, the NEPDN Regional Center processed 234 NPPLAP samples with the majority coming from a positive nursery in Oregon.

Outputs
Target Audience:Targeted audiences reached by NEPDN efforts were APS members, Arborists/Landscapers, Bramble growers, CAPS Committee, Cemetery staff, Certified Crop Advisors, College of Ag professionals, Cooperative Extension Educators, Cooperative Extension Master Gardener Volunteers, County agents, Cut Flower growers, Department of Environmental Conservation, Diagnostic Laboratory Staff, DNLA, Eastern Conservation District members, Entomologist, Farmers, First Detectors, Forest Managers and Owners, Foresters, Former Prisoners Return to Work, Fruit growers, Garden club members, Gardeners , Garden Center Employees, General public, Grape growers, Green industry professionals, Greenhouse Growers, High tunnel growers, Home gardeners, IPM Stakeholders, Land trust members, Landscape Contractors, Master gardener interns, Master Urban Gardener trainees, Middle school students, Mountaineer chal. academy cadets, NPDN Diagnosticians, Nursery workers, Organic growers, Organic Land care students, Parks Department staff, Pest control operators, Pesticide applicators, Plant pathologists, Property owners, Public Gardens, Regulatory Inspectors, Retail garden center staff, Strawberry growers, Students, Tree Fruit Growers, Tree Wardens/Council, Turf industry, Turf students and vegetable farmers/growers/producers. Changes/Problems:With substantial budget cuts, diagnostician training in new techniques has been reduced. Current conversations within NEPDN revolves around webinar-based training sessions. Such sessions would complement USDA-APHIS-PPQ-Science & Technology workshops and keep NEPDN members engaged in recent diagnostic advancement. What opportunities for training and professional development has the project provided?Diagnostic training was offered to 46 NPDN and 6 USDA participants through workshops given by the USDA-AHIS-PPQ-S&T Beltsville Laboratory on Phytophtora spp., bioinformatics, primer design, plum pox virus, citrus greening, apple proliferation, potato cyst nematode, etc. First detector training was offered to 231 new Master gardeners. Professional development events selected by NEPDN members were the 2016 APS Northeast Division annual meeting in Ithaca, NY, STAR-D round-up 2 workshop in Ithaca, NY, CTPA winter meeting in Plantsville, CT, Invasive Plant Symposium in Storrs, CT, Northeast Greenhouse Growers Conference and Expo in Boxborough, MA, Connecticut Vegetable and Small Fruit grower's Conference in South Windsor, CT, Connecticut Master Gardener Association Symposium, New London, CT, Delaware Turf and Ornamentals Nursery and Landscape Association in Wilmington, DE, Ag Extension in -Service, Maryland Ornamental Insect/Disease Conference in Hendersonville NC, MDA Boxwood Blight Meeting, in Annapolis, MD, Kanuga Ornamentals Workshop in Hendersonville, NC, Northeast Greenhouse Conference in Boxboro, MA, USDA interagency research forum on invasive species in Annapolis, MD, Entomological Society of America Eastern Branch meeting in Newport RI, Cumberland Shenandoah Fruit Workers Conference in Winchester, VA, Mid-Atlantic Fruit and Vegetable Convention in Hershey, PA, and APS-Potomac Division annual meeting in Morgantown, WV. How have the results been disseminated to communities of interest?Results were disseminated to Master Gardeners, faculty and students, vegetable growers, IPM specialists, fruit working groups, fruit tree growers, berry growers, crop advisers, high tunnel growers, county extension agents, regional extension educators, State departments of ag, department of Environmental Conservation, forest managers and owners, grape growers, green industry professionals, high tunnel growers, home gardeners, public gardens, and state and federal regulators. What do you plan to do during the next reporting period to accomplish the goals?NEPDN will continue contribute to the three overarching NPDN goals, including detection, diagnosis and reporting.

Impacts
What was accomplished under these goals? NEPDN provided professional diagnoses on 4,909 samples, including 1276 arthropods, 2077 pathogens, 221 weeds, 193 nematodes, 501 abiotic factors and 526 others using visual observations, bioassays, biochemical techniques, cultural methodologies, electron microscopy, microscopy, PCR, and seological assays. A total of 11,222 diagnoses were submitted to the NPDN National Repository in a timely manner. NEPDN members entered from 154 to 1,053 samples each with an average of 374 samples per laboratory. Several States entered first reports for the region for organisms. Examples include Fusarium stem rot on pumpkin in Delaware, armored scales on bamboo in Delaware, black leaf spot on broccoli in Delaware, skin blotch on garlic in Delaware, leaf spot on hops in Delaware, black rot and powdery mildew on kale in Delaware, blue mold on tobacco in Delaware, soybean stem borer on soybean in Maryland, fusicladium fruit sport on aronia and tomato chlorosis virus in tomato, Camarosporium on Norway spruce in New Hampshire, Cruposporiopsis abetina on Eastern Hemlock in New Hampshire, basal canker on beech in New York, Cladosporium leaf blotch on onion in New York, camellia leaf gall on camellia in New York, oyster mushroom on oak in New York, anthracnose basal rot on Itoh peony in New York, downy leaf sport on hickory in New York, Fusarium crown and stalk rot on cucumber in New York, powdery mildew on callery pear in New York, clematis wilt on cleamtis in New York, chrysanthemum thrips and chrysanthemumroot rot on chrysanthemum in New York, black rot on kale in New York, Myrothecium leaf spot on pansy in New York, Phytophthora leaf blight on English ivy in New York, darkwinged fungus gnat on parsley in New York, lesser periwinckle root rot in periwinkle in New York, black leg on potato in West Virginia, Fusarium wilt on strawberry in West Virginia, Rhizoctonia root rot of English ivy in West Virginia, tomato leaf mold on tomato in West Virginia, Phytophtora root rot on raspberry in West Virginia, Mexican bean beetle in West Virginia, cucumber beetle in West Virginia, imported cabbage worm in West Virginia, squash vine borer in West Virginia, common groundsel in West Virginia, and common cocklebur in West Virginia. NEPDN members actively engaged in numerous professional development events and activities locally, regionally and nationally. For example, NEPDN presented 30 First Detector training sessions to 686 participants.NEPDN members published 51 articles on general plant pathology, diagnosis, specific pests and pathogens and other topics. NEPDN members gave 283 presentations at various venues to 15,849 participants. The NEPDN regional laboratory led and coordinated network efforts to implement, maintain and strengthen a STAR-D laboratory accreditation system. It also continued interacting with the American Public Garden Association through the Sentinel Plant Network.
