The exact mixture used, on the basis of a 100-gallon mix, was as 

 follows: 6-2/3 gallons of 2,4-D and 2,4,5-T (half and half), 6-2/3 

 gallons of kerosene, and 86-2/3 gallons of water. 



In applying the spray, the nozzle w r as elevated at about 45 degrees. 

 Spray lines were about 20 feet apart, and the spacing of spray lines was 

 easily maintained on this small area by the wet-glossy appearance of the 

 foliage sprayed on the previously treated strip. No attempt was made to 

 thoroughly soak the whole area — that is, all understory vegetation — 

 because we recognized that the benefits from a complete kill would prob- 

 ably not compensate for the extra cost. 



Results 



The results, measured 2 years after treatment, generally supported 

 the work done by Tierson. We killed or severely damaged (to the point 

 where we judged their competitive potential was practically eliminated) 

 75 percent of the sugar maple, 94 percent of the beech, and between 85 

 and 100 percent of the other species, with the exception of white ash 

 and black cherry. As in Tierson' s work, beech proved more susceptible to 

 treatment than sugar maple.
