To Peter, Pollinators, Beekeepers, and The List, A partial copy of Peter's link is below. Please note that studies were done in the United States and Sweden, the UK, France, Germany, and Canada, also of importance is the simple fact the canola and rapeseed require the honey bee as its primary pollinator, pollinators beware! Regards, Chuck "Regulatory Note - REG2004-06 Page 29 6.1 Effects on terrestrial organisms Clothianidin was determined to be highly toxic to the honey bee, Apis mellifera, on an acute oral basis with a LD50 of 0.00368 µg/bee. The transformation products TMG, MNG, and TZMU were determined to be of relatively lower toxicity to the bee, with an acute oral LD50 of > 152 µg/bee, > 153 µg/bee, > 113 µg/bee, respectively. The transformation product TZNG was determined to be of moderate toxicity to the bee, with a LD50 of 3.95 µg/bee. Field or semi-field studies conducted in Sweden, the United Kingdom, France and Germany as well as in Ontario (Canada) and Minnesota (United States) indicated that there were no significant impacts on honey bees compared with the controls. All of the field/semi-field studies, however, were found to be deficient in design and conduct of the studies and were, therefore, considered as supplemental information only. Furthermore, the results of most of these studies indicated that residues of clothianidin, when used as a canola (rapeseed) seed treatment insecticide, were expressed in pollen and nectar of the crop plants (or collected from foraging bees) in concentrations that may pose a risk to honey bees and other pollinators. The effects on honey bee hives from chronic/long-term exposure to clothianidin residues are unknown. "Regulatory Note - REG2004-06 Page 31 Non-target terrestrial invertebrates Clothianidin is very highly toxic to honey bees, with a 48-hour acute oral LD50 of 0.00368 µg a.i./bee (= 3.68 ng a.i./bee). The transformation products TMG, MNG, TZMU and TZNG, however, were of relatively lower toxicity to the honey bees. Field or semifield studies conducted in Sweden, the United Kingdom, France and Germany as well as in Ontario (Canada) and Minnesota (United States) indicated that there were no significant impacts on honey bees compared with the controls. All of the field/semi-field studies, however, were found to be deficient in design and conduct of the studies and were, therefore, considered as supplemental information only. Moreover, the results of most of the studies indicated that residues of clothianidin, when used as a canola (rapeseed) seed treatment insecticide, were expressed in pollen and nectar of the crop plants (or collected from foraging bees) in concentrations which exceed the measured acute oral LD50 to the honey bee. The effects on honey bee hives from chronic/long-term exposure to clothianidin residues are unknown. It should also be noted that clothianidin is very persistent in soil, with high carry-over of residues to the next growing season. Clothianidin is also mobile in soil. Given the foregoing, the risk that clothianidin seed treatment may pose to honey bees and other pollinators cannot be fully assessed, owing to the lack of sufficient information and data. Clothianidin may pose a risk to honey bees and other pollinators, if exposure occurs via pollen and nectar of crop plants grown from treated seeds. " "9.0 Regulatory decision 9.1 Regulatory decision Technical grade clothianidin and the associated end-use product, Poncho 600 Seed Treatment Insecticide, for seed treatment to control flea beetle on canola/rapeseed and to control corn rootworm, corn flea beetle, black cutworm, seed corn maggot, wireworm and white grub on corn have been granted temporary registration under Section 17 of the Pest Control Products Regulations, subject to submission of the following data: • Batch data • Storage stability data (product chemistry) • Genotoxicity studies • Developmental immunotoxicity studies • Passive dosimetry or biological monitoring study • Field crop rotation study • Analytical methodology for sediment • Long-term hydrolysis study • Leaching study • Acute oral toxicity to bumble bees and leaf-cutter bees • Chronic toxicity to hives of honey bees under field conditions • Acute oral toxicity to the red-winged blackbird, house sparrow and mallard duck • Toxicity to wild birds under field use conditions." :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
