    I heard at this years Pa. turf conference that a petition has been signed and it has been requested that 2-4d's registration be pulled from the market unless they can prove that the chemical is not harmful. All markets not local. The petition was handed in on Christmas Eve. Anyone else heard this yet? The speaker's opinion was that we will lose 24d in the not so far off future.

    I have not heard anything. 24D just went through a bunch of registration. Like saying prove carrots are not harmful or stop selling them.

    The Natural Resource Defense Council is a left wing environmental group. They do need to be taken seriously. Not much of what they do is based on science.

    Thanks Turfsolutions, after years of study EPA found that 2,4-D is capable of being used safely when use according to directions.

    Now the left-leaning NRDC is in the position of telling the EPA that they are wrong. It won't sit well--but what if Obama appoints some dedicated tree huggers to the EPA? Stay tuned. Hopefully the agricultural interests will be on our side for this.

    I would think that the ag interest would be on this like flys on stink.

    One of the reason Dursban was taken off the market is because the manufactures didn't fight it. Dursban ran it's course and was off patent. Other more profitable insecticides were already in place. Dursban going off market was ideal for the chem companies

    2, 4D has gone under the gun before and survived. It may become a RUP but to totally ban of 2, 4D isn't going to happen now.

    I would not say isn't. I see some less than suitable replacements coming into the market. On the thread about kyllinga, mention was made of a herbicide named Lockup. AI of this is penoxulam. This is supposed to be a broad spectrum herbicide for the common broadleaf weeds in warm and cool season turf. Cool season turf is highly tolerant of this chemical, unlike metsulfuron. I have big issues with penoxulam, it is an ALS inhibitor, like metsulfuron, chlorsulfuron, halosulfuron and sulfosulfuron. Does anyone see the similarity? All of these chemicals have the same MOA. Kind of like how everything "thrin" is the same for insects. What I can say in favor of 2,4-D is the lack of widespread resistance to it or the other growth regulator herbicides. However, resistance to "sulfurons" is common in ag and IVM. The irony of this is weeds resistant to "sulfurons" can be killed with 2,4-D.

    I also understand the other side of this issue as well. I am well aware of the possible cancer risk and the specific sensitivity that dogs have to 2,4-D. Knowing this, I handle this valuable product responsibly. From 1996-2007, the Hawaii DOA restricted the sale and use of 2,4-D so rigorously, it virtually disappeared from the state. I can tell you, in that time, invasive vegetation took over many of the natural and noncrop areas. Except for the old time farmers and people who learned from them such as myself, no one who is in the business of IVM or lawn care knows what 2,4-D is. Sure, many people know what triclopyr is, but you cannot use that on warm season turf and it is 2-3 X as expensive as 2,4-D. MCPA and MCPP have the same issues of turf tolerance and cost. Also, it is my understanding that MCPA is much more toxic to mammals compared to 2,4-D. I have personal experience working where 2,4-D has been regulated out of existence. The idea of a national ban scares me.

    This was sent to us last year by our lawn care asso.
    As you can see it came out in August of 2007.


    (Washington, DC, August 9, 2007) – Following its recent decision to reregister 2,4 dichloro-phenoxyacetic acid (2,4-D), the Environmental Protection Agency (EPA) yesterday announced its Decision Not to Initiate a Special Review of 2,4-D, one of the most widely used herbicides in the U.S. and around the world. (Link to the EPA decision)

    EPA’s decision states: “Because the Agency has determined that the existing data do not support a conclusion that links human cancer to 2,4-D exposure, it has decided not to initiate a Special Review of 2,4-D, 2,4-DB and 2,4-DP.”

    EPA first considered Special Review for 2,4-D in 1986, and after more than 21 years of research and reregistration evaluation, the Agency was able to determine that no correlation exists between the proper use of 2,4-D and cancer.

    “Based on extensive scientific review of many epidemiology and animal studies, the Agency finds that the weight of the evidence does not support a conclusion that 2,4-D, 2,4-DB and 2,4-DP are likely human carcinogens,” according to a notice released by EPA. The herbicides 2,4-DB and 2,4-DP were also being considered for Special Review based on their similarity to 2,4-D.

    “The impact of this decision should not be understated,” said Jack Dutra, executive director of the Industry Task Force II on 2,4-D Research Data. “Today EPA definitively stated that 2,4-D is not a human carcinogen when used according to label directions. This has been one of the most widely used and successful herbicides in history, and growers around the U.S. and the world will continue to use it with confidence.”

    2,4-D is commonly applied to a variety of crops such as wheat, corn, rice, soybeans, potatoes, sugar cane, pome fruits, stone fruits and nuts. It controls invasive species in aquatic and federally protected areas, and broadleaf weeds in turf grass. An economic evaluation by the U.S. Department of Agriculture (NAPIAP Report 1-PA-96) concluded that the loss of 2,4-D would cost the U.S. economy $1.7 billion annually in higher food production and weed control expenses.

    Since 1989, the Industry Task Force II on 2,4-D Research Data developed and submitted to EPA over 300 Good Laboratory Practice (GLP) toxicology, environmental and residue studies which EPA scientists reviewed to assess the herbicide’s safety under the Federal Insecticide Fungicide and Rodenticide Act (FIFRA) and the Food Quality Protection Act (FQPA).

    The Industry Task Force II will continue to develop studies required by EPA’s reregistration review of 2,4-D, most of which are being required of all pesticides.
