    Don't you feel safe with the EPA overseeing our health,environmental concerns.

    EPA Denies Petition on 2,4-D Pesticide

    For Release: April 9, 2012
    FR Notice Published - April 18, 2012

    In a petition filed on November 6, 2008, the Natural Resources Defense Council (NRDC) requested that EPA cancel all product registrations and revoke all tolerances (legal residue limits in food) for the pesticide 2,4-dichlorophenoxyacetic acid, or 2,4-D. After considering public comment received on the petition and all the available studies, EPA is denying the request to revoke all tolerances and the request to cancel all registrations.

    By way of background, in 2005, as part of the regulatory process to ensure pesticides meet current regulatory standards, EPA completed a review on the registration and on the safety of the tolerances for 2,4-D. EPA determined that all products containing 2,4-D are eligible for reregistration, provided certain changes were incorporated into the labels and additional data were generated and submitted to the EPA for review.

    During the recent review of the petition from NRDC to revoke the tolerances, EPA evaluated all the data cited by NRDC and new studies submitted to EPA in response to the reregistration decision. Included in the new studies is a state-of-the-science extended one-generation reproduction study. That study provides an in-depth examination of 2,4-D’s potential for endocrine disruptor, neurotoxic, and immunotoxic effects. This study and EPA’s comprehensive review confirmed EPA’s previous finding that the 2,4-D tolerances are safe.

    EPA also carefully reviewed NRDC’s request that the Agency cancel all 2,4-D product registrations. Based on studies addressing endocrine effects on wildlife species and the adequacy of personal protective equipment for workers, the Agency concluded that the science behind our current ecological and worker risk assessments for 2,4-D is sound and there is no basis to change the registrations.

    2,4-D is a phenoxy herbicide and plant growth regulator that has been used in the U.S. since the 1940s. It is currently found in approximately 600 products registered for agricultural, residential, industrial, and aquatic uses. There are 85 tolerances for 2,4-D. EPA published the NRDC petition for public comment on December 24, 2008.

    Below are EPA documents responding to NRDC’s petition on 2,4-D including a pre-publication copy of the agency’s Federal Register Order. These documents are also available on EPA’s website at www.epa.gov/pesticides. A 60-day period for filing objections and requests for a hearing on the Order runs from the date of publication in the Federal Register Notice EPA-HQ-OPP-2008-0877.

    I agree with you to the extent that when someone says "2,4-D" is dangerous I get goose bumps. I used to work with this stuff until it was banned. Am I going to DIE?

    But when you go through the literature you will see that it is no more dangerous than everyday things we do and eat. Remember 2,4-D is used in preparing fields for food crops to be grown in. Our parents, grandparents were literally swimming in it.

    The EPA has even approved usage of 2,4-D as a 2,4-D ready type option to Genetically Modified Foods. Its called the Enlist line of Products. They spray the crop when it is actively growing and the 2,4-D only affects the weeds not the crop itself. It really is amazing technology.

    Now either the EPA wants us to all die and has been trying to kill us since say 1947 when 2,4-D was first approved, used and studied.

    Or some people just want to scare the pants off us, to top it off, then there are the vulchers praying on the mis informed and scared with their miracle cure.

    Don't be scared my friend.

    By the way NRDC is an activist group, Rick Smith hes the guy that wrote "slow death by rubber ducky".
    I think NRDC Rick Smith is being audited for Charity Fraud right now.

    Waiting for the day Organic world is honest enough to say that for the one running a business, we can not prevent your crabgrass or kill your broadleaves with our organic/natural/biological products. I live in the mid-south and have a nice yard with 7 turf types including tall fescue and lots of shrubs. This is my 4thy year without any synthetic fertilizers or chemicals (use round-up in dry creek bed). But I used corn glutton meal which is not practical for running a business and a 92 yr.old granny which not every has to pick weeds.
    Bought Howard Garret's book,Organic Management for the Professional. It is not honest. Can't even find crabgrass in the index. They have no solution for the business. Just don't give me that "get the soil right", not practical for a business with many yards. My problem now is that mowers and irrigation companies trump all the good efforts I put on a yard by over/under watering,mowing too low,refuse to mulch clippings.
    Don't throw out the baby with the bathwater until you have solutions!
    I think the best approach is a product like Sumagreen (never used yet) or Holganix (I use) with some good harmless (thank you gov.) 24D added to the mix. Of course need the prodiamine as a pre-emerge.
    Perhaps greediness is involved. The Green Wagon has tracks now and a lot of product pushers are climbing aboard.
    Maybe one day there will be such an affordable,practical and effective product or way to control grassy weeds and kill broadleaves but until then we will have crabgrass,roaches,mosquitoes,flies and coyotes.

    I have to be very realistic about "organic" farming, landscaping, or turf management. By nature, none of those things are natural. It is not natural to grow crops in rows in monoculture. Neither is growing grass and mowing it. I think it is rather arrogant to think that I can somehow make such a situation work according to "organic" rules as dictated by humans. Want "organic" turf? Do not ask me about the weeds because there is nothing natural about a lawn.

    2,4-D can be a poison, carcinogen. etc just as much as poisons found in nature. I understand that Fiesta is iron. Iron can be an acute or chronic poison, maybe even more so than 2,4-D because it is a metal that accumulates in the body.

    I was skeptical, but bought it hoping to learn something. Big disappointment. Too much self promotion of Garret. It is definitely not for professionals.

    If Fiesta was used as much as 2,4-D that would be a valid concern. The concept is to develop a lawn care program which requires very little dangerous inputs.

    I agree. It is often used instead of less hazardous options. If a lawn gets broadleaf weeds every spring, why is a less hazardous preemergent that targets broadleaves not used? Cost. It is cheaper to broadcast 2,4-D, then spot treat the rest of the season. I break the cycle of broadleaves using that preemergent, then thicken up the lawn. Afterwards, no need for routine herbicides.

    It is called MSM (msma) and derived from mustard seed meal. I bought some from a chemical rep. Worked well but I never got back to using it when it hurt turf coming out of dormancy which can be common depending on product. Still have a few bottles. Might bring it out and add it to my "natural" products.

    MSM Turf Selective Herbicide to control bahiagrass in bermudagrass. Control of perennial grasses and certain broadleaf weeds including dandelions MSM is labeled to control Bahiagrass, Foxtail and Ryegrass and a long list of broadleaf (dicot) weeds. It is to be used ONLY on Kentucky Bluegrass, Fine Fescue, Bermudagrass, St Augustinegrass, Zoysiagrass (Meyer and Emerald) and Centipedegrass turf areas. 2 ounce bottle
