§ 161.590 - Nontarget insect data requirements.

(a) Table. Sections 161.100 through 161.102 describe how to use this table to determine the nontarget insect data requirements and the substance to be tested.

Key: CR=Conditionally required; [   ]=Brackets (ie, [CR]) indicate data requirements that apply to products for which an experimental use permit is being sought; TGAI=Technical grade of the active ingredient; TEP=Typical end-use product.

(b) Notes. The following notes are referenced in column two of the table contained in paragraph (a) of this section.

(1) Required only if proposed use will result in honey bee exposure.

(2) Required only when formulation contains one or more active ingredients having an acute LD₅₀of less than 1 microgram/bee.

(3) This requirement is reserved pending development of test methodology.

(4) May be required under the following conditions:

(i) Data from the honey bee subacute feeding study indicate adverse effects on colonies, especially effects other than acute mortality (reproductive, behavioral, etc.).

(ii) Data from residual toxicity studies indicate extended residual toxicity.

(iii) Data derived from studies with organisms other than bees indicate properties of the pesticide beyond acute toxicity, such as the ability to cause reproductive or chronic effects.

(5) This requirement is reserved pending further evaluation to determine what and when data should be required, and to develop appropriate test methods.
