January 2016
Happy 2016!Our Department continues to excel on
so many academic and professional levels. Faculty and students published a number of refereed manuscripts and extension articles; gave a lot of presentations locally, regionally, nationally and internationally; and competed for grants to support their research and outreach. They also won a number of prestigious awards for their efforts that included American Phytopathological Society (APS)-Southern Division Outstanding Plant Pathologist Award (Dr. Ray Schneider), Louisiana County Agricultural Agents Association Achievement Award (Dr. Raj Singh), Dupont Assistantship (Ben McInnes), Monsanto Scholarship (Sanjay Pokhrel) and the APS first Departmental Plant Pathology Experiential Award (PPCP graduate students). Our M.S. and Ph.D. graduate students were highly engaged, and their efforts and outstanding contributions continue to infuse the department with
Rose Rosette Disease Confirmed in LouisianaBy Raj Singh
Rose rosette disease recently was detected for the first time in Louisiana. The disease was found on landscape Knock Out roses growing in a commercial landscape in Bossier City.
Rose rosette disease is caused by a virus known as Rose rosette virus. It is a devastating disease of roses – particularly as all cultivars are susceptible, including Knock Out roses and wild multiflora roses (Rosa multiflora). Symptoms produced by rose rosette disease are highly variable, depending on the cultivar or species of the rose and the plant’s age. Several different types of symptoms have been reported on infected roses, but some of the more recognizable symptoms of rose rosette disease include: “witch’s broom,” excessive thorniness, thickened new canes, abnormal discoloration or excessive reddening of new foliage.

Infected roses produce a cluster of new shoots from a single point on the parent canes. The new shoots elongate rapidly and appear like “witch’s broom” (Photo 1). Infected canes produce excessive thorns that are green or red and soft in the beginning but later harden off. The presence of excessive thorns, especially on newly-infected canes, is one of the most reliable symptoms to help with diagnosing rose rosette disease (Photo 2).
grafting. The eriophyid mites crawl from plant to plant or move long distances with wind. The virus is systemic and can persist in the live roots of infected rose bushes, but it is not soil-borne. Grafting of virus-infected scions on healthy root stock and vice-versa may also result in the virus transmission.
Although management of rose rosette disease in infected roses currently is not possible, several precautions can be taken to avoid introduction of the disease or to reduce its spread from infected to healthy roses. Remove infected roses completely, including roots. New growth from infected roots may serve as a source of the virus. Dispose of infected roses immediately by burning. If burning is not feasible, bag the infected roses before removal.
The wild multiflora rose is highly susceptible to rose rosette disease and eriophyid mites and may serve as a source for both the virus and the mites. Remove symptomatic multiflora roses that exist in areas close to the cultivated roses.
An integrated management of eriophyid mites, including cultural practices, may reduce the population of mites and thus the potential spread of rose rosette disease. Start with disease-free, healthy roses and inspect for any rose rosette disease symptoms before purchasing roses. Properly space out the new roses to avoid mites crawling from one plant to another. Clean tools and other equipment used for pruning.
Rose Rosette Disease
Another symptom that may be used to diagnose rose rosette disease is that infected canes are thicker than parent canes. Reddening of new foliage and shoots also is associated with rose rosette disease. A positive confirmation of the disease can be determined by amplifying the cDNA of the virus (Photo 3).
Although rose rosette disease produces unique symptoms on roses, those symptoms can easily be confused with symptoms caused by other diseases, pests, stresses and other factors. Improper use of herbicides such as glyphosate (Roundup and many other products), may result in distortion and clustering of new growth that looks like “witch’s broom”. Abnormal discoloration and distortion of new foliage has been constantly associated with rose rosette disease, but feeding injury from chili thrips, which is a very significant rose growing issue in Louisiana, also cause similar symptoms. In addition, excessive reddening of new growth is a normal character of some rose cultivars.
Rose rosette disease is transmitted by a tiny eriophyid mite, Phyllocoptes fructiphilus or by

Pokhrel Wins Competitive Monsanto Graduate Student Scholarship
Sanjay Pokhrel recently received the Monsanto Graduate Student Scholarship. He is pursuing his master’s degree in plant pathology with Dr. Clayton Hollier as his advisor. This competitive scholarship is part of Monsanto’s broader focus on innovation and investment in agriculture. The company believes investment in educating future leaders pursuing STEM careers in agriculture is the key to meeting the challenges the world faces in feeding 9 billion people by 2050. The next generation of innovators, like Pokhrel, will be the ones to ascend and meet the challenges of global food security.

Plant Pathology and Crop Physiology Graduate Students Receive the First Competitive Experiential Award from the American Phytopathological Society
Graduate students, led by Josielle Rezende, Ally Lunos and Rebecca Sweany, from the Department of Plant Pathology and Crop Physiology (PPCP) were awarded the first Departmental Plant Pathology Experiential Award by the Office of Private Sector Relations from the American Phytopathological Society (APS). This competitive award was created in 2015 with seed funding from the Don and Judy Mathre Education Endowment and through the support of private sector companies. The purpose of this award is to enhance the awareness of business operations and potential career opportunities in institutions outside of academia. With this award, the students visited several companies and governmental agencies in California, following the 2015 Annual APS meeting in Pasadena, that included Seminis, Driscoll’s and the USDA. In addition, they visited University of California, Riverside and University of California, Davis. This trip allowed the PPCP students to learn more about different career choices and see plant pathogens on crops not commonly grown in Louisiana (e.g. raspberries, blackberries, grapes and tree nuts), as well as learn about their disease management practices.

Graduate Student Association Activities
Plant Pathology and Crop Physiology graduate students were pleased to host Dr. Jan E. Leach as their invited seminar speaker, April 15, 2015. Dr. Leach is associate dean for research and university distinguised professor in the College of Agriculture, Colorado State University and an adjunct scientist at the International Rice Research Institute (Philippines). She is an authority on the molecular biology of plant pathogen interactions. Her research focuses on understanding the molecular basis of durable disease resistance, particularly in rice-pathogen interactions. She gave a seminar titled, “Understanding durable resistance in rice,” where she discussed using QTLs to identify important genes and promoters for durable resistance to plant pathogens. Dr. Leach also shared her personal and professional experiences, provided important pointers on how to market oneself plus find jobs and funding opportunities. Her main advice to the students was to be flexible and broad in their future visions and research topics.
