Dr. Smith is nationally and internationally recognized and has served in leadership positions in scientific societies such as Southern Weed Science Society, American Forage and Grassland Council, and Weed Science Society of America.  He is an active member of several committees throughout the Division of Agriculture and the University of Arkansas, Monticello.  Dr. Smith collaborates with international scientists in the UK and in Canada on different projects with international implications. 

Dr. Smith currently conducts applied research and farmer educational programs throughout the state and advises graduates students.  He has conducted approximately 500 small plot research trials and has published in excess of 75 papers in scientific journals and proceedings over the past five years.  One paper was selected as the outstanding paper in Weed Technology in 2005.  Additionally, Dr. Smith has assisted county agents throughout the state conduct over 75 weed control educational programs to over 2000 farmers and crop consultants annually.  He coauthors “MP-44 Recommended Chemicals for Weed and Brush Control” which is the most used publication in Arkansas Extension with over 12,000 copies utilized each year by farmers, industry representatives, consultants and other university personnel.  He currently gives leadership to the glyphosate resistant Palmer amaranth and horseweed management educational programs throughout the state.  The “Glyphosate Resistant Horseweed – Wanted Dead, Not Alive” educational program has been extremely successful with greater than 90% adoption rate by farmers in the areas of emphasis and has been highlighted in an Extension Faculty Conference. 

Dr. Smith gives leadership to weed control educational programs in cotton, corn, and grain sorghum and provides small plot research as well as educational support in soybean and rice.
