Titre Spirotetramat Potential Toxicity to Honey Bees

Augmentation du risque sanitaire ou environnemental
As part of its agricultural development (AD) and stewardship program, Bayer CropScience AG has conducted trials with spirotetramat to evaluate its pollinator compatibility. These trials were not conducted under GLP and formal reports were not prepared, as is typical for field efficacy and development data. Furthermore, the data were collected under experimental conditions (tent, tunnel) that exaggerate actual exposure by confining honey bees to forage only on the treated plants. These AD trials demonstrated that Movento¿¿ has the potential to affect the honey bee brood when the adults of the hive are forced to forage exclusively on flowering crops, specifically after application of Movento¿¿ to the crop at bloom or up to 5 days prior to bloom. Where effects to the honey bee brood were observed, recovery was noted within 2-3 weeks. Although the described trials indicate potential for Movento¿¿ to reduce honey bee brood production, it is important to emphasize that this has only been observed when the honey bees and the hive are artificially confined to the treated crop and, even then, the observed effects are transient (recoverable). Brood effects have not been observed in a higher tiered field study which evaluated the effects to honey bees under realistic field conditions. The field study was submitted to EPA as previously mentioned (Ref: MRID # 469044-62). While the exposure conditions of a tunnel trial are intentionally exaggerated and therefore do not represent the agronomic conditions of use, all of the trials were conducted at use rates similar to those proposed for field use in the USA and Europe. For this reason, we have decided to report them.
