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.
Prospective Students
Thank you for your interest in our Lab and in Purdue University. I receive a number of inquiries regarding the availability of research positions in the lab, and unfortunately at this time we do not have any open opportunities.

Emily Duncan
Graduate Student
Email: duncanea@purdue.edu
I have recently started to pursue my MS graduate degree in the Telenko lab. I have been a part of the research team since May 2019 as an undergraduate. 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.

Undergraduate Research Assistant
Email: myers449@purdue.edu
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.
