C. J. Willard, Professor of Agronomy, Ohio 
State University, has published the following rec- 
ommendations in Bulletin 245 of the Ohio Agri- 
culture Experiment Station: 
“Tt seems a bit absurd to apply a ton of water 
to an acre to distribute 1 to 3 pounds of active 
material on that area. . . . Dust applications have 
proven feasible, especially in pastures, along road- 
sides, and in nearly mature corn and small grains.” 
(Less than 50 pounds of Scotts 4-X Dust con- 
tains enough active material to treat an acre.) 
“Usually, 2,4-D has been most effective on seed- 
lings, young plants or during periods of rapid 
growth. . . . It may require a month or more, 
depending in part on temperature, for a complete 
kill. Judgement of the failure should not be 
made, nor retreatments started, until regrowth has 
started from the top or roots or both.” 
“Areas treated with standard amounts . . . are 
not poisonous to livestock grazing on them. Exten- 
sive tests have shown no harmful effects on ani- 
mals except from direct feeding of large doses.”
