treatment locations were again chosen for each tree and the position of application along the mainstem axis was again considered. Trees were treated with either 1.2 or 3 ml of undiluted herbicide, the equivalent amount of 60 ml of 2 and 5% dilutions, respectively. Periodic observations were conducted and treatment results were recorded in May 1978. RESULTS AND DISCUSSION Reactions to treatment of firetrees with Roundup by the above-described methods varied from slight effects to complete death of trees. The results of the 2 and 5% dilution treatments are summarized in Table 1. Although variation existed among individual trees, these results indicate a trend toward increased effectiveness among those trees treated through a lower branch cut near the mainstem. The latter treatment resulted in general death of the tree with most branches being affected, whereas treatment in an upper distal location usually resulted only in localized death. Move- ment of the herbicide throughout the tree was evident only through limited terminal dieback of other branches. Basitone trees were more difficult to treat effectively through single- site herbicide introduction than were trees with dominant mainstem growth forms since the former required substantial downward movement of the herbicide through the treated branch to reach the vascular system of the other major branches. The apparent greater efficiency of herbicide distribution in an upward direc- tion indicated a close correlation with xylem transport of water and in some instances a high degree of early selection for individual branches along the mainstem. Variation in rates of diluted herbicide absorption was noted among individual trees. Complete absorption of the entire 60 ml quantity occurred among some trees within 2 days, although most required somewhat longer for complete uptake. A few trees (Table 1) never completely absorbed the available amount during the test period. Dosage comparisons involving the latter trees are therefore difficult to make, although effects of the solution amounts actually taken up were noted. Trees treated with small quantities of undiluted Roundup reacted in a manner comparable to that described for Roundup dilution treatments. Again, herbicide introductions proximal to the mainstem and in the lowermost possible position tended to be most effective, although variation in percentage of death among individual trees was again noted, presumably resulting largely from inconsistencies in effectiveness of internal vascular connections. Complete absorption of undiluted Roundup quantities into fresh cut branch ends was markedly and uniformly rapid,
usually requiring only a few minutes. In contrast to tests utilizing Roundup dilutions, in no case did undiluted Roundup remain unabsorbed. To discover the extent to which firetrees were able to absorb undiluted Roundup, 12-ml syringe barrels or sections of half-inch inside diameter rigid-walled plastic tubing were sealed to cut branch ends of smaller and larger trees, respectively, with caulking compound. These containers were regularly replen- ished with quantities of herbicide such that during a 45-day period in excess of 100 ml of Roundup were absorbed by each smaller tree and in excess of 300 ml by each larger tree over a 32-day period. Rapid uptake continued even after portions of trees near treatment areas had developed severe visual signs of poisoning. These results dispel former concerns that attempts to introduce concentrated Roundup through a single cut branch may cause immediate death of the branch with subsequent inhibition of further uptake, resulting in ineffectiveness of the treatment method. Treatment with undiluted Roundup therefore offers no apparent disadvantage compared to the use of various dilutions, whereas the relatively small quantities required per tree and rapid absorption of the former through a single treatment site present obvious advantages. In no case was a tree killed or severely affected by either a diluted or an undiluted Roundup treatment observed to show any regenerative activity through root or lower stem sprouting. Further experimentation emphasizes determination of effective treatment methods and herbicide quantities for trees larger than those here described and for those growing in other Park elevations and habitats. Also, alternate methods for effective treatment of trees unsuitable for the cut branch method are under investigation. LITERATURE CITED Kim, J. Y. 1969. Myrica faya control in Hawaii.
