丙环康唑（PPC）和异苯康唑（DFC）常被联合用于现场应用。PPC和DFC的共存可能对其个体在土壤中的命运产生影响。研究了PPC和DFC在5种不同土壤中的吸附、解吸和淋滤作用。不同土壤对PPC和DFC的吸附差异显著，Freundlich吸附系数分别为2.86 ~ 28.69和14.86 ~ 98.93，与土壤pH呈负相关。DFC和DFC共存时，对PPC和DFC的吸附分别下降27.12-37.59%和17.28-25.35%。PPC和DFC在共存体系中迁移率增大。结果表明，土壤pH值主要影响PPC和DFC的吸附、解吸和迁移率，且两者共存会明显改变PPC和DFC个体的这些行为。
Propiconazole (PPC) and difenoconazole (DFC) are often combined for field applications. The resulted co-exsistence of PPC and DFC may have an effect on the fate of their individuals in soil. In this study, adsorption, desorption and leaching of PPC and DFC alone and their combinations were investigated in five different soils. Adsorption of PPC and DFC was significantly different on each soil with the Freundlich adsorption coefficients of 2.86–28.69 and 14.86–98.93 negatively correlated with soil pH, respectively. In addition, adsorption of PPC and DFC was declined by 27.12–37.59% and 17.28–25.35% with the presence of coexisting DFC and PPC, respectively. Mobility of PPC and DFC in tested soils was enlarged in coexisting system. The results indicate that adsorption, desorption and mobility of PPC and DFC were mainly affected by soil pH, and these behaviors of individual PPC and DFC were obviously altered by their co-existence.
