Thank you for promoting pesticide-free sustainable agriculture.
It's a hard-knock life, scouring the landscape for pollen to sustain a beehive. Alight upon the wrong field, and you might encounter fungicides, increasingly used on corn and soybean crops, and shown to harm honeybees at tiny levels. Get hauled in to pollinate California's vast almond groves, as 60 percent of US honeybees do, and you'll likely make contact with a group of chemicals called adjuvants—allegedly "inert" pesticide additives that have emerged as a prime suspect for a large bee die-off during this year's almond bloom.
Harvard researcher Lu believes that with this study, coming on the heels of a similar one he released in 2012, the colony collapse mystery has been solved.
The hardest-to-avoid menace of all might be the neonicotinoid class of pesticides, widely used not only on big Midwestern crops like corn and soybeans but also on cotton, sorghum, sugar beets, apples, cherries, peaches, oranges, berries, leafy greens, tomatoes, and potatoes. They're even common in yard and landscaping products. I've written before about the growing weight of science linking these lucrative pesticides, marketed by European agrichemical giants Bayer and Syngenta, to declining bee health, including the annual die-offs known as colony collapse disorder, which began in the winter of 2005-06.
