| Summary: | 3.1 to 12.8%, and in the reference adsorbents, from 2.1 to 63.5%. The empirical Freundlich equation adequately described activity and behavior in soils. This research was undertaken adsorbents (Gonzales bentonite, Georgia kaolinite, goethite, adsorbents and the soils using the batch-equilibration and associated parameters, preferential flow through and goethite). However, irrespective of calculation method, and Gonzales bentonite (L-type isotherm), but poorly fit the and Michigan peat) and four soils (Houston Black c, Hidalgo Black, Orelia). broadleaf weed species in cotton. However, there is a content, cation exchange capacity, and pH into the analyses curvilinear (S-type) adsorption isotherms which were observed developed for pyrithiobac adsorption on the reference did not significantly improve the correlations (W=0.48). dimethoxypyrimidin-2-ylthio) benzoate), developed by DuPont, for pyrithiobac was low compared to other herbicides based on four soils varied on the types and amounts of inorganic and greatest, followed in order by Gonzales bentonite, Georgia has shown excellent promise in controlling several obstinate herbicide pyrithiobac (sodium 2-chloro-6(4,6 in the soils and two reference adsorbents (Georgia kaolinite indicated that free iron oxide content accounted for 45% of intact or undisturbed columns. Based on breakthrough-curves K[] and K[] values. Differences in adsorption capacity of the kaolinite, goethite, and the soils. The affinity of soils macropores controlled the movement of pyrithiobac, organic constituents. Stepwise multiple-regression analyses particularly in the more structured soils (Ships, Houston paucity of information available concerning pyrithiobac physical and chemical properties. Adsorption isotherms were pyrithiobac adsorption on the Michigan peat (C-type isotherm) sl, Orelia scl, and Ships sic) having a wide range of technique. For the soils, pyrithiobac adsorption ranged from The fate of agrochemicals in soils is governed by various the retention of pyrithiobac on the Michigan peat was always the soils. Inclusion of organic carbon content, clay the variability (p < 0. 000 1) in pyrithiobac adsorption by to investigate the behavior of pyrithiobac on reference Transport of pyrithiobac was studied on four soils using transport, retention, and transformation processes.
