Abstract

C14 ring-labeled atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) was applied in nutrient solutions. Soybeans absorbed more atrazine per g of fresh weight than corn or cotton. The amount of atrazine absorbed by the plants increased with increases in atrazine concentration, in water absorption, and in length of absorption. Less atrazine was absorbed in the second than in the first 24-period wtih occasional indications of loss of atrazine back into the solution. C14O2 evolution was not established for any plant although many different environmental conditions were tried. Degradation to C14O2 is not a significant process for these plants under these conditions.
