Please explain why bees die after pollination of GMO plants with herbicide?

AExpert Answer

Thank you for your question. The lack of impact by GMO plants on bees and other pollinators has been previously answered on this web site. See one of the top 10 consumer questions about GMOs, as they relate to bees, as a starting point. The impact of herbicides has not been addressed completely but there are good places to start beginning with the answer to this question here: Do neonicotinoids and Roundup affect the wild bee populations? If so, how are you working to stop this bee killoff? Please check out these other resources that provide a non-industry perspective.


This web site provides a remarkably well documented discussion concerning the safety of glyphosate (the most common herbicide trait in GMO plants). The authors conclude that “Overall, results from a number of lab and simulated field studies generally suggest no significant risks of acute or chronic effects of glyphosate on adult Honeybees or brood production.”


Another recent article discusses the impact of insecticides and glyphosate on honey bees. For more information about bee losses and how you can help honey bees and pollinators check out this question.

When glyphosate is applied to plants (e.g., crops or weeds) a certain percentage is absorbed and transported throughout the plant. The amount absorbed is variable depending on the application rate and the type of plant. Very little of the absorbed glyphosate is degraded by the plant and cannot be removed. Its persistence in plants is also variable. Federal regulatory agencies have established allowable limits for glyphosate residues in many different crops to protect human and animal health....

The UPC (Universal Product Code) is a barcode (which has numbers beneath it) which identifies the product and the manufacturer. I think you may be thinking of the PLU (Price Look Up) code which is the 4 or 5 digit number on produce used to link a price with an item. The PLU code is a voluntary program that assigns numbers to produce items, this helps cashiers identify the correct price for a produce item. Growers/Packers can use the number "9" prefix to this 4-digit numeric code to... Read More

Thank you for your question. There are various aspects of your question. I assume your question refers to the use of Agrobacterium rhizogenes by scientists to intentionally transfer genes from the bacterium to plants. Infection and DNA transfer from this bacterium occurs in nature all the time to cause disease. Such transformed plants are not classified as GMOs since transfer occurred naturally. If this is done by scientists then it would be classified as a GMO. Rules and...
