Other claims from this paper (6)
- Observation No metolachlor residues were detected in the grain and stalk/straw of maize and soybean at harvest.
- Observation Metolachlor residues persisted in soil up to harvest irrespective of dose and crop.
- Observation Metolachlor dissipation in the field followed first-order kinetics and was faster in soil under soybean than under maize, with half lives of 16 and 18 days respectively.
- Observation Metolachlor sorption fitted the Freundlich isotherm well, with a Kf value of 1.54.
- Association Metolachlor sorption depended on soil organic carbon, with a Kk value of 398 mL/g.
- Observation Metolachlor desorption was close to sorption, with a hysteresis coefficient of 0.905 in the sandy clay loam soil.
