Cotton plants after foliar application

Mephosfolan. The metabolic fate of mephosfolan in cotton plants and in rice plants grown in a paddy environment was studied. Cotton plants were grown from seeds (Delta pine smooth leaf variety). Six-week-old plants containing 4 to 6 leaves were treated foliarly with C-mephosfolan. Plants were analyzed at periodic intervals. The distribution of radioactivity in cotton plants after foliar application of C-mephosfolan is summarized in Table V. The metabolic pathways of mephosfolan in cotton plants involve oxidation, hydrolysis and conjugation to yield glucosides (Figure 2).
