In win for beekeepers, Minnesota links insecticide to damaged hives
Source: Minneapolis StarTribune
In the first test of a landmark environmental law, Minnesota has compensated two beekeepers whose hives were severely damaged last spring by toxic dust that drifted off the fields of a neighbor planting corn.
Investigators from the state Department of Agriculture confirmed, in effect, what beekeepers have been saying for years: Even when used according to law, the most widely used class of insecticides in the world are acutely toxic to honeybees under routine circumstances.

The insecticide in question, clothianidin, is used as a coating on most of the corn and soybean seeds used in American agriculture. Farmers use it as a preventive to protect seedlings from insects in the soil. As the plant grows, the toxin grows with it, making the entire plant poisonous.

But last spring Pam Arnold's neighbor across the road planted corn that was later found to have the standard insecticide coating. On that day, the wind was blowing toward her hives, and those of Kristy Allen, another beekeeper who shares Arnolds bee yard. Allen immediately suspected what had happened. Tests performed as part of the Agriculture Departments investigation found that even two days after the incident, the dead bees carried acute levels of the toxin, and tests of nearby dandelions showed significantly higher concentrations, according to the states report.

Good for for Pam Arnold................................YEAH.........................

No. The poison in question is applied to the seed as dust. During planting it blew on the bees. Made in a chem lab.
The GMO seed may contain Bacillus Thuringensis genes that produce CRY proteins which are also toxic. Different.

(17,301 posts)You can get seed corn pre-coated with Clothianidin. It's only a neonicotinoid and is authorized for spray, dust, soil drench (for uptake via plant roots), injectable liquid (into tree limbs and trunks, sugar cane stalks etc.), and seed treatment uses, in which clothianidin coats seeds that take up the pesticide via the roots as the plant grows.
If you have coated seeds and you pass the seeds through some of those mechanical planters, a lot of dust can be kicked up. It sounds like in this case it was a dust used when seeds were planted. I've coated seeds with certain dusts when planting to speed up growth (the dusts I use are organic and wouldn't hurt a fly, literally).
But damn, I had no idea these nicotinoids drift so much and can be taken up by wild plants.

Soybeans need pollinators. But the pollen has such a low concentration of anything that it's unclear except with "there's no safe limit claims" that it's a problem. "No safe limit" here often means that the "undetectably low" amounts presumed to be there must be toxic.

Abstract
Agriculture has experienced major bio-technological advances and economic and socio-cultural disruptions since the publication of the white paper "Agriculture at Risk" in 1988. At that time it was recognized that there were acute needs in the prevention of musculoskeletal conditions, agricultural respiratory disease, noise-induced hearing loss, and pesticide-related illnesses, and the excesses of cancers noted in epidemiological studies of farmers.
In this paper, we will discuss the progress made in identification of new respiratory syndromes related to confined animal feeding operations, pesticide-related illnesses, cancers implicated with agricultural exposures, and ergonomics in agriculture. The focus will be upon the current state of knowledge in these areas, recommendations for further improvement in research techniques, and the potential application of this information to improve human health in production agriculture nation wide.
