Popis:	The application of individual droplets of an aqueous solution of As-74-labeled arsenic acid to the leaves, petioles, green stems and stalks of greenhouse-grown cotton plants (Gossypium hirsutumL. cv ‘Deltapine’) enabled the estimation of 100 ppm of As as the minimum effective internal concentration (MEIC) of arsenic from arsenic acid needed for the desiccation of cotton leaves. The spray application of arsenic acid to cotton plants (cv Lankart) in the field was calculated to have an overall efficiency of below 5 percent for this particular spraying operation. The application of aqueous arsenic acid to the abraded stalks of greenhouse-grown cotton plants (cv G-272) resulted in translocation of approximately 87% of the recovered arsenic so that treatment half-way around the stalk produced 70% desiccation. Treatment with sufficient quantities around the entire stalk resulted, in most cases, in complete desiccation and prevention of regrowth.
