The Charles studies: These respected 2,4-D published studies have strong industry links.

2013-06-27 021These studies have been cited in the various papers.  They may often appear independent when, in fact, they have strong 2,4-D industry connections:

Hoberman, Elizabeth A. Lochry and Terry Martin; Bio/dynamics, Inc., Raymond Schroeder; Springborn Laboratories, Inc., Joseph C. Siglin and Dean E. Rodwell; The Dow Chemical Company, Ashley B. Liberacki, Lisa G. McFadden, Barry L. Yano, and Carol L. Zablotny; and WIL Research Laboratories, Inc., Mark D. Nemec and Dean E. Rodwell.

Wouldn’t it be great if there was enough public sector funding so these excellent scientists could be free to research 2,4-D without industry ties?
