What opportunities for training and professional development has the project provided?During the several years of the project, the project partially supported several undergraduates and one graduate student. How have the results been disseminated to communities of interest?The project has reached thousands of IPM personnel, growers, field staff, extension personnel, and many home gardeners in the USA. The website was visited approximately 70,000 times over the course of the three years -- including persons from all 50 states. In the USA, participants have reached thousands of interested persons via, meetings, email and newsletters. In addition to the audience in the USA, persons from more than 125 countries have visited the website. What do you plan to do during the next reporting period to accomplish the goals?

What was accomplished under these goals?
Over the course of the several years of the project, the goals were met. The understanding of the target audience was improved with up-to-date information about the status of late blight in the USA. In each of the first two years there were many meetings, presentations and newsletters by participants. In each of the three years, there were rapid reports of late blight occurrences in the USA, and the genotypes causing the outbreaks was reported. The project was primarily a two-year project with most activity occuring in FY 2016 and 2017, and reports for 2016 and 2017 have been submitted previously. There were 69 genotype assessments in 2016, 48 in 2017 and 30 in 2018. US23 was the dominant genotype in each year, with a few US8 being detected. Late blight in 2018 was somewhat reduced compared to previous years, with more than 40 observations of late blight reported on USABlight. In 2018 a new genotype (US25) was detected and described. US 25 was determined to be A2 mating type, resistant to mefenoxam, and pathogenic on both potatoes and tomatoes. Of the 30 samples received by the Fry lab in 2018, most were US23, with a couple US8 and a couple US25. We sent out more than 2800 alerts during the 2018 season. Although the project was planned mainly for two years, some investigators also planted sentinel plots in 2018. There were no examples of resistance-breaking isolates of P. infestans. During the course of the project, no strains of P. infestans that could overcome Ph2 and Ph3 were detected anywhere in the 8 locations participating in the project. These genes have been incorporated into several commercially available tomato cultivars. Participants in the project continued to give talks to growers and to extension personnel. For example in the final year, participants in NY, WA, FL and PA gave talks and communicated with their IPM and grower clientele via meetings and email. Over the course of the 2+ years of the project, participants have presented up-to-date information about late blight in more than 70 meetings. Many participants also provided weekly late blight updates through diverse media including: a toll-free telephone line, e-mail delivery system during the growing season (1 April - 31 August), phone contacts and weekly newsletters. During the course of each growing season, the recipients of weekly information totaled several thousand each week. Because of the success of the project and the rapid turnaround of information (late blight location and genotype causing the outbreak), the participants are searching for mechanisms to continue the project. The clientele has been particularly interested in knowing the genotype of the strain that is causing late blight near them.

What opportunities for training and professional development has the project provided?The cooperators on the project combined to make 31 presentations to diverse groups of stakeholders. Each of these presentations was an educational meeting with growers, fieldmen, and extension staff in attendance. In many of the meetings, postdocs and students were in attendance. How have the results been disseminated to communities of interest?In each of the 31 presentations, results from the current situation were disseminated. Additionally, each of the visitors to the website had access to the current information. What do you plan to do during the next reporting period to accomplish the goals?We will continue the activities that we proposed in our application. Information obtained during the season, will be communicated to stakeholders on a near real-time basis via the website. We will continue to bring the most current data to our stakeholders via many talks presented by the co-PIs.

What was accomplished under these goals?
Late blight was much reduced in severity in 2016 compared to many previous years. The extreme dryness in much of the eastern USA was probably the most important contributing factor. Our project certainly has had some effect in minimizing the effect of some of those outbreaks. Some of these had significant impact. These occurrences were logged into the USABlight system. Thus, growers, field managers and extension personnel had current information all season long. Late blight did not occur on any of the sentinel plots conducted collaborators. Sixty-nine samples were submitted to the Fry Lab for genotypic and phenotypic assessment. In chronological order in 2016, these samples came from Florida, California, Maryland, Missouri, Washington, Manitoba Canada, Maine, North Carolina, Colorado, and Virginia. Most samples were of the US23 clonal lineage. Most individuals of this lineage have been sensitive to mefenoxam, but one sample from Maryland was resistant. This was a surprise, and was discovered because of the effort sponsored by this project. This information was conveyed to the grower and to the entire community. Reports of late blight are listed on the USABlight website. The website was visited many times In 2016. There were 21,493 site visits from 15,760 unique visitors. The most visited daywas Tues, August 2nd(166 visits). Here are other facts about the traffic on the website. User Information 141 Countries.
