Results and discussion

Any other information on results incl. tables

According to these results, the product Ferbam presents low mobility on the GH and LR soils, and intermediate mobility on LE soil. The coefficients of mobility for GH, LR and LE soils were Rf = 0.14, Rf = 0.18 and Rf = 0.51, respectively.

Applicant's summary and conclusion

Conclusions:
According to these results, the product FERBAM TÉCNICO presents low mobility on the GH and LR soils, and intermediate mobility on LE soil. The coefficients of mobility for GH, LR and LE soils were Rf = 0.14, Rf = 0.18 and Rf = 0.51, respectively.
Executive summary:

This study was conducted to determine the mobility of FERBAM TÉCNICO on three soils, LE (Typic Hapludox), LR (Rhodic Hapludox) and GH (Cnmulic Humaquept) soils. The mobility was analyzed on soil-plates using soil thin layer chromatography and autoradiography methodologies. lo uL of treatment solution (100 ug of ferbam/mL and 5 uCi/mL) were spotted in two places on soil-plates. The soil-plate quality was checked using a standard solution of 2,4 D-14C in a third spot (100 ug of 2,4-D/mL and 5 uCi/mL).

The coefficients of mobility for GH, LR and LE soils were Rf = 0.14, Rf = 0.18 and Rf = 0.51, respectively.
