dc.description.abstractPendimethalin, trifluralin and fluchloralin each were applied @ 0.5 and 1.0 kg ha-1 as a pre-plant incorporation in a field experiment carried out at College Agronomy Farm, B. A. College of Agriculture, Anand under mustard crop during rabi season of the year 2001-02 to study their persistence in a sandy loam soil with and without farmyard manure and to see their residues in mustard plant. Influence of dinitroaniline herbicides, farmyard manure and their interactive effect on the some selected soil properties viz., pH, EC, organic carbon, NO3-N, available P2O5 and available K2O was also studied. Dissipation of pendimethalin, trifluralin and fluchloralin followed first order kinetic reaction with half-life values ranging from 41.81 to 53.76, 39.09 to 43.00 and 39.61 to 47.78 days, respectively. Pendimethalin, trifluralin and fluchloralin showed monophasic mode of dissipation. Farmyard manure incorporation @ 10 t ha' decreased the herbicide residues in a sandy loam soil at all the sampling intervals. Relatively lower half-lives of 44.93 and 41.81 days for pendimethalin; 41.23 and 39.09 days for trifluralin; 39.61 and 43.00 days for fluchloralin each @ 0.5 and 1.0 kg ha-1 respectively were recorded with FYM incorporation. Residues of any of three dinitroaniline herbicides were not detected in mustard seed and straw at harvest. Dinitroaniline herbicides and FYM, singly or in combination did not exert any significant influence on pH, EC, organic carbon status, NO3-N, available P2O5 and available K2O content of soil at all the sampling intervals, except organic carbon status of soil which was significantly increased at 5th, 10th and 30th day of sampling due to incorporation of FYM @ 10 t ha-1 over no FYM. Overall results suggest that application of dinitroaniline group of herbicides tested under present study do not pose any problem of environmental contamination.en_US
