Key: R=Required: CR=Conditionally required; []=Brackets (ie. [R], [CR], indicate data requirements that apply when an experimental use permit is being sought; TGAI=Technical grade of the active ingredient, PAIRA=“Pure” active ingredient-radio labeled; TEP=typical end use product; EP =End use product.
(b) Notes. The following notes are referenced in column two of the table contained in paragraph (a) of this section.
(1) Not required if use involves application to soils solely by injection of the product into the soil or by incorporation of the product into the soil upon application.
AAA(2) Required on case by case basis depending on product use pattern and other pertinent factors.
AAA(3) Not required if anaerobic aquatic metabolism study has been conducted.
AAA(4) Required if pesticide residues do not readily dissipate in soil.
AAA(5) Confined accumulation study is required when it is reasonably foreseeable that any food or feed crop may be subsequently planted on the site of pesticide application.
AAA(6) Field accumulation study is required if significant pesticide residue is likely to be present in soil at time of plant crop, as evidenced by residue data obtained from confined accumulation study.
AAA(7) Required if it is reasonably foreseeable that water at treated site may be used for irrigation purposes.
AAA(8) Required if significant concentrations of the active ingredient and/or its principal degradation products are likely to occur in aquatic environments and may accumulate in aquatic organisms.
AAA(9) Required unless tolerance or action level for fish has been granted.
