Thiamethoxam: Assessing flight activity of honeybees foraging on treated oilseed rape using RFID technology
This study was designed to assess homing behaviour of bees foraging on winter oilseed rape grown from seed treated with thiamethoxam (as Cruiser OSR) with one field drilled with thiamethoxam treated seed and two control fields drilled with fungicide‐only treated seed. Twelve honeybee colonies were used per treatment group, 4 each located at the field edge (on‐field site), at approximately 500m ...

Brassica cover crops for Nitrogen retention in the mid-Atlantic coastal plain
Received for publication February 5, 2008. Brassica cover crops are new to the mid-Atlantic region, and limited information is available on their N uptake capabilities for effective N conservation. Forage radish (Raphanus sativus L. cv. Daikon), oilseed radish (Raphanus sativus L. cv. Adagio), and rape (Brassica napus L. cv. Dwarf Essex) were compared with rye (Secale cereale L. cv.
