Abstract and summary

The effects of various rates of 7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylic acid (endothall), isopropyl N-phenylcarbamate (IPC), and 2-methoxy-3,6-dichlorobenzoic acid (dicamba) on Bromus tectorum L. (downy brome) on four soils with surface litter and incorporated organic matter treatments were studied. Significant differences were found in reaction of downy brome seedlings to the herbicides in the four soils. The soil with the highest organic matter content generally inhibited herbicide action to the greatest extent. Straw mulch alone caused a significant decrease in growth of downy brome seedlings. Action of IPC was most inhibited by straw, and endothall the least.
