Residual fate of the fungicide tetraconazole (4% EW) in mango.

A field trial was carried out to understand the persistence behaviour of tetraconazole in mango and also in the soil of mango orchard following five applications @ 50 g a.i./ha (T(1)) and 100 g a.i./ha (T(2)). The initial deposits were found to be 0.23 and 0.38 μg/g for T(1) and T(2) doses. The theoretical maximum residue contribution (TMRC) of tetraconazole in dietary exposure appeared to be toxicologically safe for consumption as compared with maximum permissible intake (MPI). The half-life values of tetraconazole in mango were in the range of 4-5 days. The harvest samples of mango and soil were free from tetraconazole residues. © Springer Science+Business Media, LLC 2011
