A Picolinic Acid Derivative: A Plant Growth Regulator

John W. Hamaker; Howard Johnston; Robert Thomas Martin; Carl T. Redemann

4-Amino-3,5,6-trichloropicolinic acid is more toxic to many broad-leaved plants than 2,4-dichlorophenoxyacetic acid and 2,4,5-trichlorophenoxyacetic acid. It is comparable in absorption by foliage, in translocation, and in soil-leaching characteristics; in soil, however, it retains its activity for a longer time.
