New Agriculture Agents Join UMD Extension Team

By Serena Newton

The Agriculture and Food Systems (AgFS) Extension team would like to give a warm welcome to our two new Ag agents, Dwayne Joeseph (Kent County) and Mark Townsend (Frederick County).

Dr. Dwayne Joseph

Agriculture and Food Systems (AgFS) Extension welcomes Dr. Dwayne Joseph to the team. He is the new Kent County Agent who will conduct applied research and educate the public about sustainable agricultural practices. Dwayne received his B.S. in Biology from Grambling State University and then his M.S. and Ph.D. in Plant and Environmental Science at Clemson University. While attending these institutions he earned several grants and scholarships. Dwayne has years of experience designing and conducting plant science experiments related to weed control and management. Currently, he is researching integrated pest management (IPM) strategies for Maryland with a focus on integrated weed management as a postdoctoral associate for the University of Maryland, College Park Department of Entomology. He has published in several scientific journals and also communicates his findings through oral presentations and other publications, making his work both applicable and accessible. Participation on review committees for the Department of Entomology and Northeast Sustainable Agriculture Re-search and Education (NESARE) graduate student grant program, and in scientific conferences such as Weed Science Society of America meetings, makes Dwayne stand out as an immensely active member of the agricultural research and outreach community.

The AgFS team looks forward to working with Dwayne as he applies his extensive research background and strong leadership and collaboration skills to improving agricultural practices in Kent County and across Maryland.

Mark Townsend

Agriculture and Food Systems (AgFS) Extension welcomes Mark Townsend as the new Frederick County Agent Associate. He will work with the AgFS team to provide Maryland farmers with the training and resources necessary to run profitable and sustainable operations.

In the spring of 2020, Mark graduated from the University of Maryland, College Park with a B.S in Agriculture and Resource Economics with foci in agribusiness, as well as farm business management and entrepreneurship, and a minor in soil science. This fall he plans to complete a graduate certificate in Geographic Information Systems (GIS) at the University of Maryland, College Park. As a student at the University of Maryland, he was very involved as a student worker for the college of Agriculture and Natural Resources and worked as a Laboratory Teaching Assistant for a Soil Chemistry class.

Mark gained experience overseeing livestock operations as an operations manager for Rocklands Livestock Company and as a farm manager for Clark's Elioak Farm. In these positions he had several responsibilities such as implementing grazing, stocking, and nutrient management plans, and he applied his knowledge from other accomplishments such as his MDE Erosion and Sediment Control Certification, National Beef Quality Assurance Cow/Calf Certification, and passing score on the Soil Science Society of America Fundamentals Exam. As a production intern for a Maryland agri-service business, he consulted with farmers making decisions about best management practices. He currently conveys information to central Maryland farmers at biweekly Westminster Grain Marketing Meetings.

Experience working in the field, the lab, the office, and the community makes Mark a valuable addition to the AgFS team.
