Hi all-

One of the reasons given that would prevent a ban on the use of Roundup, is
that there are few or no alternatives to the use of Roundup (ag, roadways,
etc.).

Coming from the agroecological or organic perspective, in Sanet we can
provide a host of alternative weed management techniques.

However, are there any specific practices, alternative herbicides, or
scientific studies that you could cite, as an alternative to the use of
Roundup?

Below, is a link to a list of potential health side-effects from exposure to
Roundup, taken from the recent open-source EU report.

Thank-you for any leads.

18.0. Nervous system: Roundup causes neurotoxic effects

“Neurotoxicity
The 2002 review of glyphosate claims “no relevant effects” in tests for delayed neurotoxicity. But glyphosate is an organophosphate, a class of chemicals known to have neurotoxic effects, so claims of “no relevant” neurotoxic effects demand a strong and transparent evidence base to back them up.

In fact, studies from the open literature have found neurotoxic effects of glyphosate:

An epidemiological study carried out in Minnesota, USA found that the children of pesticide applicators exposed to glyphosate had an increased incidence of neurobehavioral disorders.291
In an acute poisoning incident, a man who accidentally sprayed himself with glyphosate developed the neurological disorder Parkinsonism.292
A toxicological study on rats found that glyphosate depletes the neurotransmitters serotonin (serotonin is associated with feelings of well-being and is known as the “happiness hormone”) and dopamine.293
Glyphosate causes a loss of mitochondrial transmembrane potential (a hallmark of cellular injuries) in rat brain cells.294
Glyphosate and Roundup act synergistically with the organophosphate insecticide diazinon in neuroblastoma (nerve cancer) cells. Glyphosate and Roundup become more neurotoxic when the cells have been pre-exposed to diazinon. Roundup is more toxic than glyphosate and produces effects at a concentration as low as 10 ppb, which is equivalent to a glyphosate concentration of 0.5 nM. Unusual dose-response relationships are found with both glyphosate and Roundup, which the authors say merit further investigation as they indicate that the relationship between concentration and toxicity at low concentrations may not be entirely predictable.295”

23.0. Roundup remains biologically active in the soil

“Incorrect claim about biological availability of glyphosate
The UK Pesticides Safety Directorate (PSD) notes that the issue of a waiting period between glyphosate spraying and re-entry into fields in order to protect humans, livestock, and plants, is not properly dealt with in Germany’s DAR. However, the PSD immediately dismisses this concern:
This should not be an issue for glyphosate as it is not usually biologically available once it contacts soil.349
But this claim was not true even at the time of the DAR. A 1983 study showed that glyphosate persists in sandy loam soil and is not inactivated in the 120 days prior to planting. Plants growing in the glyphosate-treated soil showed decreased nitrogen fixation, root nodule numbers and root weights – indicating that glyphosate was biologically available and toxic to plants 120 days after application.350
A new risk assessment should address the issue of the re-entry period.”

“Incorrect claim about biological activity of AMPA
Monsanto says AMPA’s long persistence in soil is of no “regulatory concern” because “AMPA is biologically inactive”.351 But a 2004 study showed that AMPA causes injury to glyphosate-tolerant and non-glyphosate-tolerant soybeans. Findings are the same when the AMPA is deliberately applied and when it forms from the breakdown of applied glyphosate. The study concludes that soybean injury to glyphosate-tolerant soybeans from glyphosate is due to AMPA formed from glyphosate degradation.352 Therefore AMPA is biologically active.
It is clear that the documents on which the existing approval of glyphosate is based are out of date and out of touch with current scientific knowledge and farmer experience.”
