Bee-killing pesticide found in garden store plants: What does it mean?

A type of pesticide that's a focal point in the controversy over endangered honeybees has turned up in garden-store plants sampled by Friends of the Earth. Other bee experts say the pilot study on neonicotinoids adds an important twist to the plight of the bees — but stress that more rigorous research needs to be done.

The study, co-authored with the Pesticide Research Institute and titled "Gardeners Beware," reported finding traces of neonicotinoid pesticides, or neonics, in seven of 13 plants purchased from garden stores in California's San Francisco Bay area; the Washington, D.C. area; and Minnesota's Twin Cities. The plants included tomatoes, squash, salvia and flowers that would be attractive to pollinators.

“Our investigation is the first to show that so called 'bee-friendly' garden plants contain pesticides that can actually poison bees, with no warning to gardeners," Lisa Archer, director of the Food and Technology Program at Friends of the Earth-US, said in a news release accompanying Wednesday's 34-page report. “Bees are essential to our food system and they are dying at alarming rates. Neonic pesticides are a key part of the problem we can start to fix right now in our own backyards." Read more >>

Mystery Malady Kills More Bees, Heightening Worry on Farms

A mysterious malady that has been killing honeybees en masse for several years appears to have expanded drastically in the last year, commercial beekeepers say, wiping out 40 percent or even 50 percent of the hives needed to pollinate many of the nation’s fruits and vegetables.

A conclusive explanation so far has escaped scientists studying the ailment, colony collapse disorder, since it first surfaced around 2005. But beekeepers and some researchers say there is growing evidence that a powerful new class of pesticides known as neonicotinoids, incorporated into the plants themselves, could be an important factor.

The pesticide industry disputes that. But its representatives also say they are open to further studies to clarify what, if anything, is happening. Read more >>
