Fs. Neto et al., Absorption, translocation, and metabolism of C-14-glufosinate in Xanthium strumarium, Commelina difusa, and Ipomoea purpurea, WEED SCI, 48(2), 2000, pp. 171-175
The absorption, translocation, and metabolism of glufosinate were investiga
ted in three differentially susceptible weeds, Xanthium strumarium (most su
sceptible), Ipomoea purpurea (intermediate susceptibility), and Commelina d
iffusa (least susceptible). Xanthium strumarium absorbed about three times
more C-14-glufosinate than Ipomoea purpurea and about six rimes more C-14-g
lufosinate than Commelina diffusa. Translocation of the applied herbicide o
ut of the treated leaf was low. No evidence of glufosinate metabolism, eith
er in the treated leaves or roots, was found when the extracts were separat
ed by HPLC.
