Background

I am a native of the Finger Lakes Region of Western New York State. After graduating from the State University of New York (SUNY) College at Geneseo with a B.S. in biology in 2001 I moved to North Carolina. At NC State University I earned my M.S. degree in plant pathology in 2004. My thesis was titled “Biology and Epidemiology of Sclerotinia minor on Peanut (Arachis hypogaea L.).” I continued on with my doctoral research at NC State University and earned my Ph.D. in plant pathology in 2007. My dissertation title was “Improved Strategies for Controlling Sclerotinia blight of Peanut: Site-specific Disease Models and Advisory, Fungicide timing, and Pathogen Detection.” I then moved to Oklahoma State University where I was an assistant professor of plant pathology and horticulture extension pathologist in the Department of Entomology and Plant Pathology from 2007-2012. I conducted research on diseases of turfgrass, grapes, and pecans. I joined the faculty of the Department of Plant Pathology at The University of Wisconsin-Madison in September 2012. I was promoted to associate professor and extension plant pathologist in July 2018, and promoted again in July 2022 to professor and extension plant pathologist. I have research and management responsibilities for diseases of field crops including soybean, corn, wheat, and alfalfa.

Education

Education:

M.S., 2004, North Carolina State University – Plant Pathology

B.S., 2001, State University of New York (SUNY) Geneseo – Biology

Research

Research Interests:

My overall research goal is to better understand the biology and epidemiology of economically important pathogens to improve disease management for sustainable food and feed production. This research is translated for the consumer and delivered through the extension arm of my program not only in Wisconsin, but also regionally, nationally and internationally. Our research influences the major agronomic commodities (corn, soybean, small grains, and alfalfa), affecting over 10 million acres of harvested crops in Wisconsin each year. These crops provided over $2.2 billion in cash receipts or about 20% of Wisconsin’s farm gate income in 2015.

Extension

Extension Efforts:

My extension efforts focus on generating, evaluating, and disseminating solutions to many of the disease problems associated with field crops such as soybeans, corn, wheat and alfalfa. Information and potential solutions to disease problems are evaluated using applied research. Field studies include station and on-farm research to test epidemiological models, conduct pesticide evaluations, and improve the practical and biological understanding of various plant pathogens. I work closely with county extension agents, crop advisors, agribusinesses, and commodity groups to improve the management of the major diseases affecting field crops. I am responsible for developing disease management fact sheets, outreach courses, and electronic education resources.

Carol L. Groves, Ph.D. – Scientist II

I received my Ph.D. in Plant Science from the University of Arkansas then went on to a Post-doctoral position at North Carolina State University (NCSU). It was at NCSU that I began working with Phytophyhora infestans, the causal organism of Late Blight of potato and tomato. I spent several years at NCSU and with the USDA-ARS in Orono, Maine working on P. infestans. I took a few years away from science to raise my two children before coming back to work first in the UW-Entomology department and currently in the UW-Plant Pathology department.

My current responsibilities include managing the Field Crops Plant Pathology Lab, mentoring students and conducting research on soybean diseases, including but not limited to, soybean vein necrosis virus (SVNV), brown stem rot, pod and stem blight, and white mold. I also support the extension portion of the Field Crops Pathology program by writing, updating and revising extension literature.

Please contact me anytime at cgroves@wisc.edu.

Brian Mueller – Researcher II

I received my B.S. in Biology from the University of Wisconsin-La Crosse and earned my M.S. degree in plant pathology at the University of Wisconsin-Madison in 2017. My research in graduate school involved assessing an integrated management program for the control of stripe rust, caused by the fungal pathogen Puccinia striiformisf. sp. tritici, and examining population differences and aggressiveness characteristics of Fusarium graminearum, the primary causal agent of Fusarium head blight (FHB). Currently, I am the field technician for the Field Crops Plant Pathology Program.

Camila Primieri Nicolli – Postdoctoral Research Associate

I am from a small town in south of Brazil. After graduating in Agronomy at the University of Rio Grande do Sul, I earned my M.S. degree in plant pathology in 2014. After my MS, I continued my studies with Fusarium and mycotoxins in row crops at the University of Lavras in Minas Gerais state where I earned my Ph.D. in plant pathology in 2018. I then moved to Goiás state at the University of Goiás in Goiânia, where I was an assistant plant pathology professor in the Department of Agronomy for about one year. During my time as a professor, I taught general plant pathology, plant protection, and mycology to undergrad and grad students. I also conducted research on diseases of sugarcane. After the academic experience, I moved to BASF Brazil, adding my expertise to the seed treatment R&D team. In February of 2021 I moved to Madison Wisconsin to become a post-doc and pursue my “American dream”. Currently, I am doing applied research focusing on corn disease management strategies, working under the NPMTI project to develop and validate prediction tools for diseases and mycotoxins affecting corn.

Rodrigo Pedrozo – Postdoctoral Research Associate

For the past few years working as a plant pathologist, I have had the opportunity to interact with different plant pathossystems and gain experiences with some of the greatest professionals in the field. The focus of my research projects is primarily related to the understanding of the influence of plant pathogens on seed quality of cash crops and how to better manage them. My interests range from testing seed treatments with chemical molecules and/or biological agents in lab, greenhouse, and field trials to using advance molecular tools (i.e., metagenomics) to detect plant pathogens and explore the microbiomes of seeds. Originally from Piracicaba, São Paulo-Brazil, I came to the US for an internship at UC-Berkely and I stayed afterwards for my PhD at Kansas State University. Currently, I am joining forces with Dr. Smith’s research team at UW-Madison to create, applied, and improve digital tools to help manage diseases in corn and soybean crops in the state of Wisconsin.

Maxwell Ozioma Chibuogwu – Doctoral Student

I am originally from Agbor in Delta state, but I grew up and spent most of my life in Benin City, Edo State, both of which are in southern Nigeria. I obtained my bachelor’s degree in plant science and biotechnology in 2017 from the University of Benin, Benin City, Nigeria. There I worked on honing my molecular skills and performing tissue culture research on a medicinal plant called Moringa oleifera. After my undergraduate studies, I worked in a couple of research institutions as an intern but spent the most time at the International Institute of Tropical Agriculture (I.I.T.A), Ibadan. At IITA, I worked at the Genetic Resources Center (G.RC.) which broadly focused on collecting, storing, propagating, and distributing germplasm. I also worked with the bioscience center where molecular techniques were applied to meet the goals of the G.R.C. In January 2020, I joined a virology lab at the University of Arizona where I briefly worked on witches’ broom disease caused by a virus in the blue palo verde tree. I joined the Smith Lab in the Fall of 2020, and I am working on understanding the disease system (including toxin formation) of Gibberella ear rot and Gibberella stalk rot caused by Fusarium in silage corn. This understanding will help me recommend best management practices to farmers for better management of the disease and toxin production.

Kelly Debbink – Masters Student

I am originally from Pennsylvania, where I completed my B.S. in Animal Biotechnology & Conservation at Delaware Valley University. Since then, I’ve spent much of the last decade in the southwestern US working on conservation and infrastructure projects. My interest in the environment and conservation eventually led to my interest in agriculture and the role it plays in the health of the environment. After working on a small, organic farm in Wisconsin and witnessing some of the disease struggles firsthand, I became interested in plant pathology as well. I joined the Smith Lab in 2021 to pursue a master’s degree with a focus on integrated disease management in organic field crops. The goal of my research is to provide organic farmers with disease management recommendations by conducting field trials on genetic, unput-based, and agronomic disease management techniques.

Sarah Caroline de Souza – Master’s Student

I am originally from a countryside city in the state of Sao Paulo, Brazil. In 2016 I started my bachelor’s degree in Agronomy at the Federal Institute of Education, Science, and Technology in the Southern Minas Gerais State where I graduated in 2022. During college, I mostly dedicated my time to researching different management tools for crops like soybean, corn, sorghum, and sunflower as well as studying the introduction of new wheat cultivars, in partnership with other universities in the state. In 2020 I was selected by the Ohio State University to participate in the international internship program for one year at the company South Central Growers in Springfield — TN, where I participated in the management and measurements of fertigation system parameters and collaborated on pot and garden trials of new cultivars. In 2022, in the state of Rio Grande do Sul located in the south of Brazil, I developed trials to test different chemical fungicides and their effects and results on soybean, corn, and wheat diseases along with different combinations of management tools to improve the results provided by fungicides aiming at better control of foliar and soil diseases. In 2023 I started my Master’s program in Plant Pathology at the University of Wisconsin – Madison while I collaborate in the research led in Damon Smith’s laboratory. The main focus of my research is to identify where are the areas with the occurrence of populations of Phytophthora sojae and Phytophthora sansomeana in the state of Wisconsin and determine what resistant soybeans cultivars available commercially, should be deployed in the state. We will use this information to improve the management recommendations for Phytophthora diseases in Wisconsin.

Amit Sharma – Doctoral Student

I am originally from Ludhiana city in the state of Punjab, India. Since I was always curious about plants, I chose agriculture as a field of study at very prestigious institute, Punjab Agricultural University (PAU), India which offered diverse coursework and practical training, which allowed me to obtain varied perspectives on upcoming challenges in agriculture locally and globally. I graduated with Bachelor’s in Agriculture (Hons.) in 2019 with specialization in crop protection with distinction where I enjoyed every bit of it as it was challenging to solve the mystery behind sick plants. After my undergrad, I worked as an intern in Department of Plant Pathology, PAU, where we performed field and lab experiments with Sclerotium oryzae causing stem rot of rice. My work was focused on studying the morphological and molecular variability of Sclerotium oryzae, different inoculation methods to test pathogenicity, testing various chemical fungicides and bio-control agents, and evaluating the virulence pattern of different isolates of Sclerotium oryzae on different rice cultivars having different level of resistance/susceptibility. I was then awarded with the Presidential Graduate Research Assistantship for my Master’s degree in Biology at University of Texas Rio Grande Valley. My MS research was focused more on epidemiological aspects, on how weather parameters influenced the incidence of citrus canker caused by the A^w strain of bacteria in the Rio Grande Valley. I joined the Smith Lab in Department of Plant Pathology at University of Wisconsin-Madison, in spring 2023, where my research is focused on Sclerotinia stem rot in soybean caused by Sclerotinia sclerotiorum. We are using a combination of field work and lab techniques to better understand the pathogen and epidemiology of the disease. It will help us to disseminate better management practices to farmer for controlling Sclerotinia stem rot. Additionally, I like to cook, read, run, exercise, and act.
