For me the real issue is not any single pesticide. Rather it is the persistent exposure to multiple pesticides at low levels which may act synergistically on the body over long periods of time, i.e. from gametes to adulthood and into succeeding generations. A 3 or 4 year study on mice of one or several pesticides is an incomplete picture and does not take into account all the potential relevant variables. The other issue is that ag workers, like I have been in the past, are not necessarily as careful with the pesticides as we should be. Walking into a shed (or Lowes at this time of year) with 20 or 30 ag chemicals can increase the exposure many times over to individual ag chemicals, not to mention the potentially toxic combination of all the volatiles stored there. At the same time, minimally trained ag workers are not working in a lab environment. So, spills and splashes are going to happen without proper clean-up or decontamination of affected skin/clothing. If I can smell it, I get worried about the exposure my body is experiencing. This Saturday afternoon we are hosting a permaculture group to tour our yard. The focus will be on using native birds, pollinators and wildflowers to enhance the production of our organic garden. If it works on a 500 sq. ft. garden it can be applied to larger areas. Imagine a pasture or barn surrounded by bird boxes for insect and weed control instead of using multiple chemicals to do the same. We live north of Reading, Berks County, PA, about 5 minutes from I-78. Drop me a note if interested Richard Gardner

I certainly hope nobody takes medical advice form me, but a cursory examination of the causes of Parkinsons include (as with the vast majority of diseases) a complex interaction between genetic variation and environmental triggers. I have attached the paper that Michael cited if anyone I sinterested. To be clear, the paper doesn’t assess a direct link between glyphosate and Parkinsons, but rather, it presents a case that suggests that glyphosate (negatively) influences a normal cell process that is thought to be associated with Parkinsons.
I am a bit concerned about the tone of this paper, even though it is peer-reviewed. The first sentence of the abstract states: "Herbicides have been recognized as the main environmental factor associated with human neurodegenerative disorders such as Parkinson's disease(PD).” Since it is in the abstract it isn’t supported with a citation. But it also isn’t supported with a citation anywhere else in the manuscript and I can find no peer-reviewed article that would actually support this claim. That is cause for concern to me.
I certainly don’t mean to suggest that pesticides can’t be dangerous. Far from it. I’m also not commenting here on the adequacy of current testing and procedures. I just think that the papers I can find don’t suggest a strong role for glyphosate as a cause for Parkinsons. My reading of it is that the there may be some merit and it may warrant further investigation, but to me the case seems very speculative at present.
Best,
Norris

Norris and All,
Appologies for the nature of the article I just sent, I am in the field on mobile and regret that I have limited capacity for deep research into these concerns at the moment.
Here is an article from NIH looking into possible modes of action regarding links to Parkinsonism:
http://www.ncbi.nlm.nih.gov/m/pubmed/22504123/
I was hoping for a serious discussion because there do seem to be some warranted concerns from this an other studies.

The citations here seem very tangentially related to the issue and amount to cherry picking of the data. Very few of the studies are on glyphosate. Many of the studies are note even about pesticides in general. I am certainly wary of overuse of pesticides, and perhaps there may be legitimate concerns related to Parkinson’s, but the studies here present a weak to non-existant cace in my opinion.

All,
I have been more concerned with glyphosate's possible link to Parkinson's Disease more than anything else, here is an article with scientific citations:
http://oradix.com/news/9/Parkinson%27s-Disease%3A-Caused-by-Glyphosate-%28Monsanto%29-and%7B47%7Dor-Trichloroethylene%3F.html

Thank you for the article on glyphosate studies versus cancer. Does anyone
know if the same study has been done for other health concerns, such as
asthma? Many thanks.

For your reading pleasure:
The attached articles came from a professor and extension specialist from
Washington State University who is speaking on the human health risks of
glyphosate. These peer reviewed articles include the latest comprehensive
review of the risk of glyphosate used for coca eradication on human health,
an article that reviewed glyphosate and carcinogenicity issues, and a third
that reviewed non-cancer outcomes. All found no consistent pattern of
positive associations indicating a causal relationship between cancer and
exposure to glyphosate.
