| Abstract/Contents: | "An increased rate of butylate (S-ethyl diisobutyl-thiocarbamate) degradation occurred on a Kennebec silt loam (sil) exhibiting rapid EPTC (S-ethyl dipropylthiocarbamate) breakdown in the field. Butylate degradation was not as rapid as EPTC degradation on field soils previously treated with EPTC. Addition of R-33865 (O, O-diethyl-O-phenol phosphorothioate) to butylate extended its persistence in field soils with and without prior EPTC application. Although microbial degradation of butylate, EPTC, and vernolate (S-propyl dipropylthiocarbamate) was increased on EPTC-pretreated soils, EPTC and vernolate degradation was much more rapid than butylate degradation. Addition of R-33865 to butylate, EPTC, or vernolate extended their soil persistence on soils pretreated with EPTC. In a laboratory experiment, a maximum rate of EPTC degradation resulted from one prior application. The rate of butylate degradation increased with each successive butylate application, but the degradation rate was not as high as those observed for EPTC on EPTC-pretreated soil." |
