How 2,4-D Hurts Pets & Wildlife

How 2,4-D Hurts Pets & Wildlife

Dow’s Enlist Duo threatens household pets and other animals. Pets, farm animals and wild animals don’t know when and where a weed killer has been applied.  They wander into 2,4-D-sprayed corn and soybean fields, roll on 2,4-D-treated lawns, eat 2,4-D on foliage and drink water contaminated with 2,4-D.  For these reasons, they are often exposed to more intense concentrations of herbicides and insecticides than people.

A 2004 study by Purdue University scientists showed that Scottish terriers exposed to lawns treated with herbicides such as 2,4-D had greater risk of bladder cancer than other terriers. A 1991 National Cancer Institute study concluded that dogs exposed to just four lawn treatments a year significantly increased their risk of malignant lymphoma. Domestic animals accidentally exposed to large quantities of 2,4-D can suffer lethargy, weakness, vomiting and convulsions. Hunting dogs near farmland are already at risk of exposure to 2,4-D and other pesticides from agricultural runoff onto wetlands where duck and other wildlife live. Tripling 2,4-D applications on crops would put these animals in even more danger.


Wild animals do not have owners to look out for their safety. The EPA says that 53 endangered species, including four mammals and five birds, would be potentially at risk from increased 2,4-D use in the Midwest, where corn and soybean farms abound. The EPA said the risk could be managed by confining 2,4-D to fields, but it did not explain how wildlife and plants would be kept out of pesticide-contaminated fields.

Honeybees are particularly vulnerable to pesticides. Bee colonies are collapsing in alarming numbers throughout the world.  They are at heightened risk from 2,4-D. EWG’s analysis of documents disclosed by the EPA found that even in short-term tests for 2,4-D exposure, honeybees showed a variety of toxicity symptoms, including slow response to stimuli, reduced coordination, loss of equilibrium, hyper-excitability, lethargy, immobility and death.


Drift of 2,4-D from sprayed fields would destroy flowering plants essential to pollinator colonies, causing significant economic harm. Other important insect species such as monarch butterflies are known to suffer from pesticide toxicity.

The bottom line: 2,4-D is harmful to pets and wildlife. EPA should not approve  Dow’s Enlist® Duo for large-scale spraying on tens of millions of acres of American farmland.

But 2,4-D is one of the most thoroughly tested herbicides in the world, over 50 years in fact, and while tt is sometimes reported in the news media that lawn and turf herbicides containing 2,4-D are a cause of cancer in dogs, this has not been supported by the simple fact that all of the regulatory agencies that have scientifically examine the data have reached the same conclusion: 2,4-D is not an animal carcinogen.

Barbara L stated earlier that: "Sigh. Didn't we learn anything from the past? i.e., DDT, Agent Orange, Round-Up -- we are poisoning the planet and all life thereon. Because corporations want their profits and politicians their graft..."

Barbara L, we have to remember, that 'Rounding Up' the profit margin outweighs the trifling consideration of the welfare of all life on the planet. If we one day end up with a lifeless planet because of all of the toxins permeating the environment, then we will all 'rest' with the 'comfort' of knowing that the CEO's died both happy and richer. Of course, they can't take it with them but they really don't care about trifling matters such as that or if there will be a living green planet left in the future, therefore, the March of Profits Before Everything Else, continues unabated! The only green that matters to them is ...the colour of green money.

Certainly when it comes to the welfare of wildlife, chemicals and other toxins and wildlife do not mix and often causes the destruction of habitat, not to mention the dying off of a lot of wildlife. Bees certainly would be far more numerous if it were not for the products Monsanto and its ilk.

What can I say that hasn't been said already. Enough is enough, stop destroying the planet and it's inhabitants!!!!
