This collection of herbicide ingredient properties is presented with references as a decision-making aid. Decision-makers may need to compare herbicide active ingredients according to their water solubility, half-life, sorption potential, and other factors. These properties can help to predict an herbicide's movement through soil, water, and air.

Click on the name of an active ingredient to get started, or click the upper left button "Show list view" for a simpler view of the data. NPIC has made every effort to locate values for each herbicide, emphasizing EPA as a source of experimentally-derived data. Empty cells reflect a lack of data found after searching EPA dockets, peer-reviewed literature, and other sources. Textbook values may be available; call NPIC to learn more if you need values that are missing from the table.
