The potential for herbicide carryover is directly linked to which two primary chemical/application characteristics?

Answer

The chemical's half-life and the concentration applied.

The likelihood that herbicide residues will survive long enough to harm a subsequent sensitive crop is directly proportional to how long the chemical typically lasts (its $ ext{DT}_{50}$) and the initial quantity that was applied.
