Dear Dr. Alejandro, thank you for raising awareness of the issue of traces of glyphosate.
Before commenting further, I would appreciate your help understanding the issue a bit better.
First, what exactly are the "traces of glyphosate" that are detected? The active molecules in glyphosate degrade almost immediately upon exposure to sunlight and air. Therefore, it is hard to understand how the active ingredient in glyphosate could remain on cotton for months between the time of harvest and sale at the retail level. I am wondering if the "traces of glyphosate" that are found on consumer products are actually inert molecules whose origin may be unrelated to the herbicide.
Second, if traces of glyphosate herbicide are found on cotton, what could possibly be the mode of transmission that would have placed glyphosate molecules on the cotton in the first place? Farmers use glyphosate to control weeds, and the herbicide is sprayed during the growing season. Once a leaf canopy has been established, further applications of glyphosate are usually unnecessary, and once cotton bolls have opened, there would rarely be need for additional applications of herbicide in a field. Therefore, cotton bolls are not normally sprayed with glyphosate, and therefore it is hard to envision how traces of a herbicide could be found on cotton fiber months after harvest.
Thank you, and I look forward to discussing this issue further after reading your replies.
