In an Oct. 2014 Bloomberg News article, Dow Chemical’s CEO, Andrew Liveris, said he is “counting on Enlist Duo to help double earnings at Dow AgroSciences in five to seven years.”
Enlist Duo is AgentOrangeGMO, the herbicide combo using half of Agent Orange (2,4-D); glyphosate, the active ingredient in Roundup; and other unknown chemicals. That herbicide combo is sprayed on food seeds that have been genetically engineered to withstand repeated applications of those two herbicides. 

But chemistry is not math: the chemicals could cause far worse health hazards when they interact than when used individually. There are no studies showing how those two active ingredients will interact with each other and gestating babies, kids, adults,livestock or pets. Multiple studies show probable to definite dangerous health effects for each of the active ingredients in Enlist Duo. Therefore, it seems wise to reject either half of Agent Orange as a food additive (especially since it was designed as an herbicide) until all the data proves there are no ill health effects.
Forcing Monsanto and Dow to wait on selling chemicals embedded in food until studies are completed showing the long term health effects from all the chemicals in Enlist Duo can only be accomplished by a federal government committed to its folks’ health. It will be a difficult sell. Those six companies are Dow and Dupont, which are in merger talks, SyngentaBASFMonsanto and Bayer, which is considering buying Monsanto.

It is common practice for the FDA to require pharmaceutical companies to test future medications for 9-12 years before a new prescription drug is allowed on the market. Many drugs are tested, some do not make the grade for medical use and thus commercial feasibility. It is not assumed the drugs will be harmless, they must be proven so.
That is not the case for the chemical companies making our foods. GMOs are granted GRAS status—meaning Generally Recognized As Safe without actually having to prove it. Although the chemical companies don’t want to wait until the scientific data proves the chemicals in our foods are harmless to humans, they should be required to take the same steps that pharmaceutical companies must take for prescription drugs.
Ironically, most drugs do not affect the tens of millions of people the way the widespread use of glyphosate (Roundup) and 2,4-D (Scott’s Weed and Feed) do since they are the #1 and #3 most used herbicides in this country.  Enlist Duo would combine both of those herbicides plus a chemical surfactant, probably a chemical adjuvant, and maybe a third chemical for a preservative.  We know for a fact, that glyphosate deposits residue on the food we eat that has been sprayed. In fact, one of glyphosate’s traits is its ability to penetrate the plants and translocate through the plant tissues. (Please see "Herbicides Sticking to Our Dinner" section & "Kids and Cancer" section)
