EPA Announces Plan to Require Disclosure of Secret Pesticide Ingredients 

Pesticide manufacturers are allowed to use nearly 4,000 inert compounds in their insecticides, herbicides and other pest-killing products. Since 1987, they have been required to list on labels only about 50, including asbestos and cadmium. Nearly all of those have disappeared from pesticides since then.Under federal law, only the EPA has authority to require information on pesticide labels, so state officials cannot act on their own.

Some scientists have been concerned about the toxic effects of inert ingredients. A recent study from CRIIGEN (Benachour et al, 2009 - read more file “Roundup”on our website) found that one, called polyethoxylated tallowamine, or POEA, used in the popular herbicide Roundup is more deadly to human embryonic, placental and umbilical cord cells than the herbicide itself.

MDRGF Proves that Roundup Formulas Do Not Correspond to the Approved Formulations

Monday 30 November 2009

"Well done to our friends of MDRGF who are continuing to work on the products the toxicity of which was highlighted by CRIIGEN, including Roundup adjuvants."


MDRGF proves that both Roundup® formulas as registered at the French Ministry of Agriculture do not correspond to the formulations of the product sold on the market.


Following analyses carried out upon the request of MDRGF and Jacques Maret in relation to both Roundups® (RU), formulations, the results underline weaknesses in the marketing of the RU in question.

A Mayor Demands the Withdrawal of Roundup Herbisides from a DYI Store

Thursday 19 November 2009


The socialist mayor of Vert of Vert-Saint-Denis (Seine-et-Marne Region, East of Paris) has demanded that Roundup herbisides be withdrawn from the shelves of a DIY store in neighbouring town, following recent CRIIGEN research work.


The chemical in question is a weed-killer, the Roundup, which, according to the mayor, pollutes the ground water in Champigny. The ground water in Champigny supplies drinking water to one million people in the Seine-et-Marne and part of the Essonne regions, as Stéphane Daron, Mayor's Cabinet Executive Officer, stated to AFP (Agence France Presse), thus confirming a piece of information from the local edition of Le Parisien.


Stéphane Daron stated: "We heard that Roundup active agents were recently traced at the bottom the sheet of water. This is definitely an issue in terms of human health and biodiversity", he said, referring to a scientific paper from the University of Caen which demonstrates the noxiousness of Roundup.


According to Daron "this is going to lead to extra costs for the users in the sense that we are going to need to find some procedure to decontaminate drinking water".


The town hall sent three letters to the headquarters of the store in Cesson since May 2009, criticising them for promoting the product, thus encouraging citizens to use it" and demanding/suggesting that it should be withdrawn from the shelves of the store, "in a civic gesture", added M. Daron.


He regretted that "so far, we haven't heard from Leroy-Merlin".


The townhall admits the limits of its action, saying that ideally the herbicides ought be withdrawn from the stores, but the trouble being that these products have been approved by the Ministry of Agriculture".


However, they want to bring the case before the association of communes in Sénart (San) which comprises nine different municipalities in the region and before the General Council of the Département.


According to AFP, Leroy-Merlin headquarters are refusing to comment. 


Roundup is the number one selling herbicide worldwide and it is produced by the US company Monsanto.

The Court of Cassation Dismisses Appeal for Misleading Advertising

Tuesday 27 October 2009


The Court of Cassation Dismissed Mossanto’s Appeal for Misleading Advertising 6 October 2009


Tuesday, 27 October 2009

The Court of Cassation (the highest court in the French judiciary) dismissed the last appeal lodged by Monsanto, making the sentence to a 15000 € fine for misleading advertising definite. 


An advertisement was presenting the glyphosate-based Roundup herbicide as biodegradable, leaving the soil “clean”. Following a complaint lodged by associations like Eau & Rivières de Bretagne and UFC-Que choisir (a consumer association), the Court of  Appeal of Lyon had sentenced Mosanto company in October 2008, confirming a sentence dating from January 2007, and highlighting “a presentation (on the packaging of the product) dodging the potential danger of the product by the use of reassuring words which mislead the consumer”. 


Glyphosate is the main active ingredient of Round Up and classified by European authorities as “dangerous for the Environment”, mainly for water, and suspected to be an endocrine disruptor following the publication of a study in July by the Committee for Independent Research (CRIIGEN).

Different Roundup Formulations Lead to Embryonic, Umbilical Cord and Placental Cell Death and Are Poorly Assessed - January 2009


For the first time, the toxicity mechanisms of four different Roundup formulations were studied in human cells. They act at doses where they are not herbicides anymore. The cells were neonatal cells freshly isolated from the umbilical cord, or less sensitive cell lines specially used to measure pollutant toxicity.
