cotton plants grown in solution culture were exposed to arsenic trioxide (as//2o//3) from 0 to 8 $mu$ g as ml** $minus$ **1. arsenic was readily taken up by the roots but was not translocated to the shoots. in contrast, when carcodylic acid was applied in the range of 0-40 $mu$ g as ml** $minus$ **1, as was found not only in the roots but also in the leaves and reproductive structures. plants treated with the herbicides msma and dsma also accumulated as in the roots and shoots. the defoliant, cacodylic acid, was applied as a foliar spray at the commercially recommended rate to cotton plants with green and mature bolls. cottonseed from the treated bolls did not accumulate as above 2. 6 $mu$ g as g** $minus$ **1, the tolerance limit. however, at higher application rates, the as concentrations increased in the cottonseed. 18 refs
