KTOXNET PIP -TRIFLURALIN Page 3 of 4 <br /> activity will be gone [8]. It is strongly adsorbed on soils and nearly insoluble in water [111. Because adsorption is <br /> highest in soils high in organic matter or clay content and adsorbed herbicide is inactive,higher application rates <br /> may be required for effective weed control on such soils [58,8]. Trifluralin has been detected in nearly,1%of the <br /> 5590 wells tested. However, it has been detected at very low concentrations,typically ranging from 0.002 ug/L to <br /> 15 ug/L [8]. <br /> . Breakdown in water: Trifluralin is nearly insoluble in water [1]. It will probably be found adsorbed to soil <br /> sediments and particulates in the water column. <br /> . Breakdown in vegetation: Trifluralin inhibits the growth of roots and shoots when itis absorbed by newly <br /> germinated weed seedlings [58]. Trifluralin residues in crop plants will occur only in root tissues which are in <br /> direct contact with contaminated soil. Trifluralin is not translocated into the leaves, seeds, or fruit of most plants. <br /> On most crops,trifluralin applied to the leaves has no effect, but on certain crops, such as tobacco and summer <br /> squash, leaf distortion may occur [58]. <br /> Physical Properties: <br /> .
