From bad to worse? - NRDC tells EPA to oppose new Enlist Duo pesticide

Earlier this year we told you about how glyphosate – commonly known as Round Up – was responsible for contributing to the dramatic decline in monarch butterflies by eliminating milkweed, the one plant the monarchs depend on to reproduce.  Round Up has been so effective that scientists have documented a huge decline in the presence of milkweed in agricultural fields and along with it, a corresponding decline in monarch butterflies.  But other types of weeds have actually developed a resistance to glyphosate and no longer respond to the application of this pesticide.  Therefore, the chemical companies are looking to address this problem.  Naturally, their solution is: Even more pesticides!  

Dow Chemical recentlypetitioned the EPA to register a new pesticide that combines glyphosate with another pesticide: 2, 4D.  The same company has developed genetically engineered corn and soy that withstand both of these pesticides.  This way farmers can douse their fields with two pesticides at once and eliminate any weeds, including those that are resistant to glyphosate, all without harming their crops. .  So tell me, what happens when the weeds develop resistance to 2, 4 D? 

Anyone can see where this is headed – a snowballing effect of more and more powerful pesticides that threaten both wildlife and human health.  This is hardly a sustainable solution.  That’s why NRDC submitted comments to the EPA highlighting the agency’s failure to address the impacts that the combined use of glyphosate and 2, 4 D will have on the environment and on public health. 

Several months ago NRDC also filed a petition with EPA to evaluate glyphosate given the impacts it is having on the imperiled monarch population.  At a minimum, EPA should not allow the registration of this new cocktail of pesticides until it has conducted that evaluation. Furthermore, there are significant public health concerns with the expanded use of 2, 4D that need to be addressed.  But more than anything, EPA needs to acknowledge that going down a path of approving more and more pesticide combinations will not produce not a sustainable or healthy future for anyone.  Two wrongs will never make a right.

Do you have kids? Wouldn't you like them to know a butterfly too?

Deborah HulsewedeJul 1 2014 05:07 PM

We rarely see butterflies. Leave them alone.

Chuck NewtonJul 1 2014 06:58 PM

We don't need Round-Up type pesticides. People overuse and abuse them.

Barbara ShermanJul 1 2014 07:28 PM

Stop killing. Stop the Roundup. Now.

Deborah MohlerJul 1 2014 10:04 PM

Stop the killing!!! Your killing our butterflies!! What will it be next, our birds, our rabbits, squirrels, our pets. Stop the use of Round-Up and stronger pesticides!!!

Linda LyerlyJul 1 2014 10:07 PM

We need to plant milkweed. Are there many varieties ? But even so why does society have to face disaster before we see the Light? And make a change??!

Barbara MonroeJul 2 2014 12:15 AM

Please save the butterflies, the bees and the birds!

Christina BombardJul 2 2014 01:16 AM

Stop round-up! The end of pollinators marks the end of food!

Poisons kill us all. Greed is poison. Everything dies.

Roundup is not only killing butterflies, it's toxic to humans. Look at the rise in deadly cancers.

Leslie RittenbergJul 2 2014 11:19 AM

Find something safer please.

Jacqui MelmanJul 2 2014 11:31 AM

Please stop using chemicals!!! You are destroying nature and our livelihood here on earth. You should be ashamed of yourself and how little respect you have for life and this planet!!!

Kathleen KovacsJul 2 2014 05:09 PM

Annie ConnrosJul 2 2014 06:30 PM

Please change your chemicals to something that will not bite the hand that feeds us!
We will crush you. You will go out of business. We will not buy the product and we will spread the word through social media, friends and family.

These pesticides are strong and indiscriminate,. The monarch is a visible victim; there are so many other species we do not notice that are also disappearing. Shame on us for putting greed first.

Could you give me some alternatives to Round Up? Our yard has quite a few different kinds of weeds, but mainly Johnson grass, crab grass, and clover. I use Weed and Feed, and Roundup. I don't want weeds in our lawn. I also have a problem with weeds growing under the deck, so I spray there also. Everyone around here does it. So give me a good, effective alternative. We also have fire ants, but we put out some kind of powder in their nests that kills them. We do have plenty of butterflies. Now if you can tell me what to use for Japanese beetles.

Save us all from highly toxical Glyphosate now!

Donna FranklinJul 9 2014 01:00 PM

When will they stop? will they wait until all the animals are extinct? Stop the pesticides! The money won't buy or bring back our precious animals.
