Study Says Roundup Much More Toxic Than Glyphosate (How To Avoid)

[Clyde]

Glyphosate is just one of Roundup's many ingredients but possibly the only one that goes systemic in the plants. You may be avoiding the more toxic Roundup by removing shells, outer leaves...and selecting foods like white rice with the exterior removed so you're not eating material that made contact with other chemicals.

Abstract​

Roundup is a glyphosate-based herbicide used worldwide, including on most genetically modified plants that have been designed to tolerate it. Its residues may thus enter the food chain, and glyphosate is found as a contaminant in rivers. Some agricultural workers using glyphosate have pregnancy problems, but its mechanism of action in mammals is questioned. Here we show that glyphosate is toxic to human placental JEG3 cells within 18 hr with concentrations lower than those found with agricultural use, and this effect increases with concentration and time or in the presence of Roundup adjuvants. Surprisingly, Roundup is always more toxic than its active ingredient. We tested the effects of glyphosate and Roundup at lower nontoxic concentrations on aromatase, the enzyme responsible for estrogen synthesis. The glyphosate-based herbicide disrupts aromatase activity and mRNA levels and interacts with the active site of the purified enzyme, but the effects of glyphosate are facilitated by the Roundup formulation in microsomes or in cell culture. We conclude that endocrine and toxic effects of Roundup, not just glyphosate, can be observed in mammals. We suggest that the presence of Roundup adjuvants enhances glyphosate bioavailability and/or bioaccumulation.

The question is, when is glyphosate ever used as a stand-alone product? If almost never, than we can assume the effects of Round Up might be prevalent in almost anything that is sprayed. I would guess most commercial crops are sprayed with the Round Up, but who knows. Either way, glyphosate should be avoided if possible.

New Study: Undisclosed Inert Ingredients in Some Popular Roundup Products Found to Be Highly Toxic to Bumblebees

Popular herbicide products widely available at hardware and garden stores contain undisclosed “inert” ingredients that can kill bumblebees, according to a new study published in the Journal of Applied Ecology. The study compared several products, most of which contained the herbicide...

Pesticides are manufactured and sold as formulations that contain a mixture of compounds, including one or more active ingredients and, potentially, many inert ingredients. The inert ingredients are added to pesticides to aid in mixing and to enhance the products’ ability to stick to plant leaves, among other purposes.

Inorganic grain crops, like wheat, are routinely sprayed with Round-up to dry out the crops quicker for early harvesting…

“Roundup conditioning must be well-timed and managed for the greatest value and harvesting efficiency.

• Treat crops only once the Roundup timing has been reached
• Employ coarse droplets and use low drift nozzles to safeguard margins and hedgerows
• Adjust sprayer boom so the spray pattern correctly covers the target
• Spray early in the day to optimise uptake in dry weather
• Leave crops for the statutory minimum of 14 days before harvesting
• Delay harvesting for up to 21 days post-treatment in unfavourable weather”

Roundup Use Pre-harvest

Roundup can be used pre-harvest of winter and spring cereals, (wheat, including Durum, barley and oats), oilseed rape, mustard, peas, field beans and linseed
