Abstract

The effect of temperature and relative humidity on root and foliar uptake of C14-labeled atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) in quackgrass (Agropyron repens (L.) Beauv.) was studied in a controlled environment growth chamber. Uptake and translocation of root-fed atrazine increased as temperature increased. Greater uptake and translocation of root-fed atrazine occurred under low relative humidity than under high relative humidity. Slightly greater uptake and translocation of foliar-applied atrazine occurred as temperature was increased from 60 to 80 F.
