Abstract/Contents: | "Absorption and translocation of 14C-metriflufen {2-[4-(4- trifluoromethylphenoxy)phenoxy]propanoic acid} in johnsongrass [Sorghum halepense (L.) Pers.] and soybean [Glycine max (L.) Merr. 'Lee 68'] were evaluated under different environmental conditions. At 40% relative humidity (RH), an increase in air temperature from 18 to 35 C increased translocation of the 14C in johnsongrass more than four-fold following application of 14C-metriflufen to an area on the third leaf. At 100% RH, translocation of the 14C was twice as great at 27C as at 18C, but translocation at 35C was intermediate. In the combined analysis, translocation in johnsongrass was no better at 100% RH than at 40% RH. Regardless of level of RH, most translocation in johnsongrass at 18 and 27 C was toward the distal half of the treated leaf, but at 35 C most translocation was toward the proximal half of the treated leaf. Translocation of 14C in soybeans increased more than four-fold as air temperature was increased from 18 C to 35 C, and more translocation occurred at 100% RH than at 40% RH at 18, 27, and 35C. More than 80% of the 14C-metriflufen remained in the treated leaf or on the surface of treated soybean leaves 48 hours after application. More of the applied radioactivity was recovered from soybean plants than from johnsongrass plants." |
