Abstract: Toxicity of nonradiolabeled
and translocation of 14C-labeled metriflufen (2-(4-(4-trifluoromethylphenoxy)phenoxy)
propanoic acid ) in cotton (G. hirsutum L. 'Stoneville 213')
were evaluated under different environmental conditions as
affected by surfactant and by the maturity of stem or leaf
tissue at the place of herbicide application. Cotton was very
tolerant to metriflufen, with the greatest tolerance at high
temperatures. The herbicide entered the plant quite rapidly
and autoradiographs indicated that radioactivity from the
herbicide moved freely throughout the plant. Relative humidity
(RH) of 40-100% had little effect on metriflufen toxicity.
Two weeks after treatment with metriflufen at 0.5 kg/ha cotton
was essentially free of injury symptoms at 35ê C, but
injury was as great as 41 and 13% at 18ê and 25ê
C, respectively. All plants recovered fully after 6 additional
weeks in the greenhouse. When surfactant was added to the
spray solutions cotton injury was frequently increased during
the first 2 wk but not after 8 wk. Accumulation of 14C at
the site of 14C-metriflufen application was 31-65% after 48
h. Between 16-51% of the applied 14C moved from the treated
area by translocation to other parts of the plant or by volatilization
into the atmosphere. Movement was greatest from stem tissue
at 35ê C and 100% RH. There was no correlation between
14C movement and herbicide toxicity within the plant. The
selectivity of metriflufen to cotton probably results from
deactivation by or tolerance within, the plant rather than
form differential absorption and translocation of the herbicide.
