1“Under evaluation” means no classification decision has been made and the use/formulation in question is still under active review within EPA.

2Percentages given are the total of dioxathion plus related compounds.

3(Note—M-44 sodium cyanide capsules may only be used by certified applicators who have also taken the required additional training.)
