For those have very short half-lives (phoxim and dichlorvos) or relatively high MRLs (cyhalothrin and b-cypermethrin) (Table 6), the tMRL of both treatments was shorter than their recommended PHIs. Like its crunchy cousins, it needs a cooler temperature to grow its beautiful purple leaves. As is shown in Table 3, the vapor pressure of dichlorvos is at least four orders of magnitude higher than any other pesticide, which means dichlorvos has the highest volatility of the selected pesticides which could probably explain its fast dissipation in bok choy. 2004).
