396 Third Year After Application (1961): Observation of th~ P'l~t~' the' thiia ·yeal"-_,'af:t.e;rapplication! (Table VIII) indicated only 10 to 30 per cent vegetation control at the 10 pounds per acre rate; 10 to 60 percent control at the 16 pounds per acre rate; 20 to 90 per cent control at the 32 : pounds per acre rate; and 10 to 80 per cent control at the 64 pounds per acre rate. In general, most of the area which showed some degree of below-plot injury to vegetation due to herbicidal transport the first and second years Was recovered from the harmful effects by the third year. (Table IX) Most of· the areas which recovered from the effects of the herbicides are now filled in with the species of grasses adjacent to the area. SUMMARY In general there are a few main conclusions that can be offered: 1) There was no long term significant difference due to source of material under the conditions of this study; howeve!,? the rate of active herbicide used was significant up to the third year after application. It is doubtful that. ,any visible control will be evident by the fourth year after application, even at the highest rates. 1 , 2) It would appear that the optimum vegetation control per dollar of expenditure would be obtained at the 16 pounds per acre active herbicide rate. 3) Type of soil (sandy soils used in tll.1s study) might pt'esumably have some bearing upon the rate of vegetation recovery', and upon the, extent of down-slope transport of the herbicide. 4) Prevention of concentrated water running over treated areas would materially help to reduce down-slope transport of herbicides. (There is no substitute of good construction and sound run-off control.) r . 5) Departmental experience with 6 to 8 year vegetation control under guide rail fences after soil sterilization with herbicidesis presumably the result of an adequate bitumen cover applied immediately over the sterilized area? rather than to the rate or kind of herbicidal soil sterilant Whlch was used. Thel bitumen cover prevents re-entry of viable seed to the treated soil, and materially helps to prevent down-slope transport of the ~homi~Q' i~~o'~_
