Similar observations have been reported for prchloraz  and benthiocarb
 in water where dissipation was independent of pH and was subject to photodegradation following pseudo first order kinetics.

Pendimethalin [N-(1-ethylpropyl)-2, 6-dinitro-3, 4-xylidine], Benthiocarb [3, 5-dinitro-N-4, N-4-dipropyl sulfanilamide] and Oryzalin [S-4-chlorobenzyl diethyl thiocarbamate] (Fig.
After this initial equilibrium, columns were loaded with Pendimethalin, Benthiocarb and Oryzalin @ 10.0, 10.0 and 7.7 kg a.i.
Final volume was made up by n-hexane and residues were estimated by GLC (Agilent Technologies 6890N Network GC system) with [Ni.sup.63] electron capture detector (ECD) coupled with Chemito 5000 data processor for Benthiocarb and Pendimethalin.
Benthiocarb [(S-4-Chlorobenzyl diethyl thiocarbamate); S-4-Chlorobenzyl diethyl (thiocarbamate)] is a thiocarbamate group of herbicide, used as a pre/post emergent herbicide in the paddy field .
Fate and behavior of benthiocarb (thiobencarb) herbicide in biota and the environment [7, 8] and laboratory leaching studies of Oryzalin and diuron  have been done.
Standard stock solution (1000 mg [L.sup.-1]) of analytical grade benthiocarb was prepared in ethyl acetate.
