Help me do my job

Adriana Murillo-Williams

I would like to introduce myself as the Agronomy Extension Educator for Clinton, Centre, Mifflin, and Juniata counties. My name is Adriana Murillo-Williams and I am honored of taking over this position where I will be working with the Penn State Extension Agronomy Team.


I have a Bachelors in Agronomy from the University of Costa Rica, a Masters in Plant Pathology from Iowa State University (ISU), and a PhD in Crop Production and Physiology, also from Iowa State University.

During my time at Iowa State I worked with the Soybean Extension Program where we helped farmers address their concerns about crop production and yield losses.

After I graduated from ISU, I returned to Costa Rica and worked for the “Centro para Investigaciones en Granos y Semillas” (Seed and Grain Research Center) at the University of Costa Rica (UCR) as the Mycotoxin Laboratory Coordinator. I had teaching, research and extension responsibilities at UCR.

My research focused on mycotoxigenic fungi and mycotoxin reduction strategies, and I also worked closely with industry, state phytosanitary agencies, and producers on mycotoxin detection and quantification in agricultural commodities.



I am here to help farmers solve any agronomy related problems and questions that they may have, provide up to date science-based information in the field of agriculture, and organize ag-educational programs, workshops and field days.

Be prepared, as there may be occasions when I do not have an immediate answer to your questions, and when that occurs, I will reach out to the Penn State Extension Specialists in the areas of, soils, agronomy, weed management, forages, plant diseases, and farm management to find the best answers.

During 2019, I will be involved in the Soybean-On farm Research Network in projects looking at soybean yield limiting factors, fungicide seed treatments, and good inoculation practices.

I am also part of the slug population monitoring project and the Sentinel Plot program, In addition, along with our extension plant pathologists, Dr. Alyssa Collins and Dr. Paul Esker, along with support from the Soybean Cyst Nematode (SCN) Coalition (https://www.thescncoalition.com/). We will be offering free nematode testing for farmers during the 2019 planting season across Pennsylvania.

With this project, we want to learn about the distribution and population levels of SCN and other plant parasitic nematodes in the state, and for that, we need your help!

We have a limited number of nematode free tests per county, so if you are in Clinton, Centre, Mifflin, or Juniata counties, and are interested in the program, please contact me directly as soon as possible. Farmers located in other counties who are interested in the SCN program and a free sample should contact your local Agronomy Educator.

I am also involved in a project funded by the Pennsylvania Malt and Brewed Beverage Industry Promotion Board with the objective of developing educational materials on malting barley grain quality. If you are a malting barley grower and you would like to get involved, we would love to hear from you!

Farmers, I am looking forward to working with and learning from you. However, in order to organize educational programs that really target your needs, I need your input.

Please help me do the best job possible and provide your thoughts! I can be reached via email at axm1119@psu.edu, or at the Cooperative Extension Office at the Willowbank County Office Building, 420 Holmes St., Bellefonte by calling 814-355-4897.
