This study is required for both parent trichlorfon and DDVP (using a technical grade active ingredient product for both studies). This study is required for both parent trichlorfon (using a typical end-use product) and DDVP (using a technical grade active ingredient product). This study is required for both parent trichlorfon (using a typical end-use product and DDVP (using a technical grade active ingredient product.) This requirement involves the submission of validated environmental chemistry methods only, not the submission of a terrestrial field dissipation study. Environmental chemistry methods used to generate data associated must include results of a successful confirmatory method trial by an independent laboratory. Teststandards and procedures for independent laboratory validtion are available as addenda to the guideline for this test requirement. The current 40 CFR Part 158 data requirements require Tier I level seedling emergence data for all insecticides with outdoor uses. As other organophosphates are known to be phytotoxic, registrants are encouraged to conduct a Tier II study rather than a Tier I, since any adverse effects (even if <25%) will necessitate a Tier II study. A Tier II study should enable the Agency to conduct an endangered species assessment for nontarget plants. The current 40 CFR Part 158 data requirements require Tier I level non-target aquatic plant data for all insecticides. As other organophosphates are known to be phytotoxic, registrants are encouraged to conduct a Tier II study rather than a Tier I, since any adverse effects (even if <25%) will necessitate a Tier II study.

A Tier II study should enable the Agency to conduct an endangered species assessment for nontarget plants. Required to support the ornamental/bait fish pond use. The registrant is encouraged to consult with the Agency on protocols. Required for the trichlofon degradate dichlorvos (DDVP). A study protocol must be submitted for review by the Agency prior to initiation of this study. Not required when the chemical is to be applied only by soil injection or is incorporated in the soil. For the passerine study only, data are required for exposures to both trichlorfon and DDVP. Environmental chemistry methods used to generate data associated with this study must include results of a successful confirmatory method trial by an independent laboratory. Test standards and procedures for independent laboratory validation are available as addenda to the guideline for this test requirement. Case # and Name: DCI Number: 1 Page: of

Data using the TGAI are required to support all outdoor end-use product uses including turf. Data are generally not required to support end use products in the form of a gas, a highly volatile liquid, a highly reactive solid, or a highly corrosive material. Data are required on one passerine species and either one waterfowl species (mallard duck) or one upland game bird species (bobwhite quail) for terrestrial, aquatic, forestry, and residential outdoor uses. A passerine study protocol must be submitted for review by the Agency prior to initiation of this study. Data are required on one estuarine/marine fish species. Data are required on an estuarine/marine fish. Data are required for an estuarine/marine invertebrate. Data are preferred on mallard and bobwhite quail. Data are generally not required for outdoor residential uses, other than turf, unless data indicate that pesticide residuesfrom the proposed use(s) can potentially enter waterways. Data are generally not required for outdoor residential uses, other than turf, unless data indicate that pesticide residues from the proposed use(s) can potentially enter waterways. 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 columns may be more appropriate to fully characterize the potential mobility of the parent compound and major transformation products.
