• Responses of Eastern Red Cedar to Control Procedures

      Various chemical, mechanical, and burning procedures were evaluated for control of eastern red cedar (Juniperus virginiana L.). Injection treatments of picloram caused 70 to 100% desiccation and plant kill at several dates of application but 2,4,5-T did not. High rates of granular picloram applied in either August or March caused greater desiccation than did lower rates. Picloram alone or in combination with 2,4,5-T or 2,4-D as wetting foliar-stem treatments caused good kill, as did high rates of other herbicides. Low volume foliar treatments of picloram plus 2,4,5-T killed much but not all top growth. Sprouts occurred on 22% of the mowed small (0.5 to 1.25 inch basal diameter) trees. Trees less than 3 feet tall were more easily killed by burning than larger trees. Wheat (Triticum aestivum L.) and little bluestem (Andropogon scoparius Michx.) seed germination was not affected by water-extracts of eastern red cedar, but switchgrass (Panicum virgatum L.) germination was. The reverse was true of coleoptile growth.
