Abstract

Gas chromatographic and thermoelectric methods were combined in a quantitative study of absorption and movement of 4-amino-3,5,6-trichloropicolinic acid (picloram) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) in bean plants in various intensities of moisture stress.

Foliar absorption of the herbicides studies was unaffected by extreme moisture stress. Herbicidal movement in the plant was markedly reduced, however. Distribution patterns were affected only when stress was permitted to progress to the wilting point. Picloram was more mobile than 2,4,5-T at all stresses.
