The degradation trends of both difenoconazole and propiconazole
in different matrices are in the same pattern but at different
degradation rates. The data of half-lives in straw and soil demonstrate
that the degradation rate order is: straw < soils. The residues
of difenoconazole and propiconazole are much higher in straw
than in those in grain. The residues of difenoconazole and propiconazole
in wheat grain samples are not detectable (i.e.,
