CHEMICAL CONTROL OF VEGETATION-1959 AAR REPORT

The United States and Canada have been divided into seven general regions based on similar soil types, climatic conditions and vegetation to evaluate the results of yearly treatments of chemicals for weed control in roadbed and ballast. More than 80 types of chemicals and chemical combinations are available for vegetation control purposes. Combinations of these continue to be the most widely used for weed control on main lines and branches in all regions. Soil-sterilant type materials were used primarily in yard areas, around bridges and trestles, communication poles, signal stands, buildings, road crossings and as spot treatments. Among chemicals used for these purposes were sodium arsenate, Atlacide-2, 4-D, Baron, Benzabor, Simazine and Urox. These materials provided good results for one season in all regions when applied at recommended rates. In low rainfall areas it is possible to obtain two year control. Oils continue to be used primarily in the Midwest, South and Southeast. A single application provides fairly good control in the Midwest. Two and three treatments are necessary in the South and Southeast. Specifics for each of the seven regions are discussed.
