Such sites include, but are not limited to cranberry bogs and rice paddies. Not required for contained pesticide treatments such as bait boxes and pheromone traps unless adverse effects reports are received by the Agency.2. Not required for known phytotoxicants.3. Not required for aquatic residential uses. Adsorption and desorption using a batch equilibrium method is preferred. However, in some cases, for example, where the pesticide degrades rapidly, soil column leaching with unaged or aged column may be more appropriate to fully characterize the potential mobility of the parent compound and major transformation. 1.
