1 2 3 4 5 6 7 8 Key: Residue of Concern = Residue of Concern; TEP = Typical End Use Product [TEP]; TGAI = Technical Grade Active Ingredient [TGAI]; TGAI/PAIRA = Technical Grade of the Active Ingredient or Pure Active Ingredient, Radio Labelled; TGAI, TEP = Technical Grade of the Active Ingredient or Technical End-Use Product; TGAI/PAI = Technical Grade Active Ingredient, Pure Active Ingredient

Refer to public draft guideline 850.4225 for guidance on Tier II seedling emergence testing. Data are required on one freshwater aquatic invertebrate species. The preferred test species is Daphnia magna. Data are required for six species of dicots from at least four families, one species of which is soybean (Glycine max). Data are required for four species of monocots from at least two families, one species which is corn (Zea mays). At least one of either the monocot or dicot species must be a root crop. Based on the use pattern and anticipated duration of human exposure, a 28-day inhalation toxicity study may be conducted in lieu of a 90-day study. An environmental chemistry method and associated independent laboratory validation for tribenuron methyl residues of concern in soil are required. An entire terrestrial field dissipation study is not required. All 90-day subchronic studies in rats can be designed to simultaneously fulfill the requirements of the 90-day neurotoxicity study using separate groups of animals for testing. Although the subchronic guidelines include the measurement of neurological endpoints, they do not meet the requirement of the 90-day neurotoxicity study (guideline 870.6200). A draft protocol must be submitted to the Agency within 90 days of receipt of this DCI for review and approval by the Agency prior to study inception. A Tier II study is required. A Tier I plant study may be conducted in lieu of a Tier II study with the understanding that any adverse effects observed by the Tier I study would necessitate conduct and submission of a Tier II study as well. The purpose of a Tier II study is to establish both a definitive No Observed Adverse Effect Concentration (NOAEC), or alternatively, a concentration at which there is a 5% observed inhibition effect (IC05), to be used in a risk assessment and effects determination for endangered or threatened species (listed species), and a definitive IC25 (concentration at which there is a 25% observed inhibition effect) for assessing risk to non-listed nontarget plants. If any adverse effects are observed in a Tier I study and neither a definitive NOAEC nor a definitive IC05 value is available, then the Agency may have to presume in its effects determination, that tribenuron methyl "may affect" and is "likely to adversely affect" listed plant species.
