48 WATERHYACINTH 



amine of 2,4-D in water. Since 1948, the Louisiana Wildlife and 

 Fisheries Commission has conducted extensive control programs 

 on waterhyacinth, and at present such activities have covered 

 nearly half of the infested sections of the State. Efficiency in 

 operations has been increased substantially recently by using 

 lighter, lower-pressure spraying equipment and larger, more pow- 

 erful barges. In a 1955 report on waterhyacinth investigations, 

 the Florida Everglades Experiment Station in cooperation with 

 the U. S. Agricultural Research Service and the Central and 

 Southern Florida Flood Control District has advocated the use of 

 1 pound acid equivalent of 2,4-E) amine per acre. The report in- 

 dicates general expectancy that a 90% to 95% kill will result from 

 the initial treatment.
