Abstract
The loss of atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] from metal planchets was decreased by an increase in the amount applied and linseed oil (LO) additive. LO reduced volatility to a greater extent than did other additives. Vapor loss from plant leaves was influenced by plant species, plant leaf maturity, soil moisture, concentration of atrazine applied, volume of oil additive, type of additive, and duration of exposure. Generally, atrazine uptake by plants was inversely related to volatility. Uptake and translocation of 14C-atrazine label was increased more by oil additives than surfactant (SURF) compared to no additive. LO increased 14C-label translocation more in yellow foxtail [Setaria glauca lutescens (Weigel) Hubb.], green foxtail [Setaria viridis (L.) Beauv.], and barnyardgrass [Echinchloa crus-galli (L.) Beauv.] than in corn (Zea mays L.).
