Data from supervised trials on mangoes are summarized in Table 7.
Residues, application rates and spray concentrations have generally been rounded to 2 significant figures or, for residues near the LOD, to 1 significant figure. Residues are not corrected for recoveries.
The trials were fully reported and well documented. Ferbam was analysed by a CS2 evolution method and residues had been expressed as ferbam. All the residues reported in this monograph are expressed as CS2 irrespective of the original expression. The theoretical factor 0.547 was used to calculate CS2 values from ferbam values.
Ferbam was applied to two test plots of mangoes by an airblast sprayer. Each test plot comprised 93 trees. Four replicate samples were taken from each plot at each sampling and analysed separately. Samples were stored at -18°C for 3-3 1/2 months after harvest before analysis.
Table 7. Residues of ferbam (as CS2) in mangoes (Tommy-Atkins variety) from foliar applications of ferbam WG in supervised trials in the USA. The 4 values at each PHI are from 4 replicate samples. Residues are expressed on a whole fruit basis.
