Telenko Lab - About Us
Our research program focuses on promoting sustainable and economically sound disease management practices in Indiana field crops. We have an interdisciplinary plant pathology research and extension program involved in studying the biology and management of soilborne and foliar pathogens of agronomic crops.
This research encompasses four major themes:
- Detection and monitoring of disease pathogens to minimize and/or detect the development of fungicide resistance or impact of new diseases in field crops.
- Integration and evaluation of new chemistries or tools into cropping systems.
- Evaluation of host resistance.
- Exploration of new biopesticide options to improve disease management.
The information generated from our research program is used to support extension efforts focused on providing timely and reliable information to growers and industry stakeholders to encourage the adoption of integrated management strategies for improved production efficiency and increase awareness of how diseases impact crop yield potential in Indiana.

As a Field Research Associate, I am responsible for setting up and maintaining field trials in corn, soybeans, and wheat for disease management research. My job consists of field mapping and trial set up, equipment maintenance and transportation, planting, pesticide applications, trial maintenance, data collection, and harvesting.

MSc 2021 - State University of Maringa, PR, Brazil - Plant Protection
BS 2018 - State University of Maringa, PR, Brazil - Agronomy
I am a visiting scholar and help with laboratory activities such as pathogenic fungi inoculation, molecular techniques, isolation of fungi and field activities such as labeling stakes, seed counting, rating plant diseases in soybean, corn and wheat, application of fungicides to control pathogens, collecting data, processing data, running statistics, writing manuscripts according to the data collected. I also will be part of a project about tar spot, a very important disease that has been gaining prominence since it was discovered in the United States in 2015.

Emily Duncan
Undergraduate Research Assistant
Email: duncanea@purdue.edu
I am an undergraduate student majoring in Cellular, Molecular, and Developmental Biology at Purdue University. I have been a part of the research team since May 2019. My role has been to assist in field and lab activities. These jobs include planting crops, disease rating, data processing, fungi inoculation, DNA extraction, and running gel electrophoresis. This lab has allowed me to use my molecular biology knowledge and apply it to corn, soy, and wheat diseases.

I am an undergraduate student majoring in Biology. This is my first year in the lab, and I
am excited to see what research has in store for me. My role is to assist graduate students with
their research projects by collecting field data to analyze disease severity and incidence,
maintaining plots, and helping out in the lab through activities like DNA extraction.

I am an undergraduate student majoring in Natural Resources and Environmental Science with a concentration in Environmental Quality and Restoration. I've always had a passion for the environment, and in true Midwest fashion I’m excited to focus that passion on corn and soybeans this summer. My job this summer is going to have me out in the field planting crops and collecting soil samples as well as entering trial data in the lab. I’m excited to use my existing soil knowledge this summer, expand on that, and support the research that is being done in the lab in whatever way that I can.
