Abstract

Abstract: Zoxamide is a benzamide fungicide applied to control diseases caused by oomycete fungi. Fertilizers are important agricultural supplies to adjust soil properties and increase nutrition. To investigate the impact of zoxamide and seven fertilizers urea, phosphate fertilizer, potash fertilizer, compound fertilizer, organic fertilizer, vermicompost and soya bean cakes on the soil environment, the enantioselective dissipation characteristics of zoxamide, soil enzyme activities, pH and N, P nutrition changes were comprehensively analyzed in our present study. The enantioseparation method was successfully validated to quantify the zoxamide enantiomers in soil by HPLC using Chiral NQ (2)-RH column. Our results demonstrated that the R -(−)- and S -(+) - zoxamide half dissipated in the range of 10.88–17.81 and 8.05–14.41 days, respectively. S -(+)-zoxamide disappeared faster in soil. The vermicompost accelerated the dissipation rate of S -(+)-zoxamide, while urea, phosphate, organic and vermicompost fertilizer increased the dissipation selectivity. Zoxamide and fertilizers other than urea caused soil acidification during 80 days. Zoxamide was beneficial to soil catalase, instead inhibited soil urease, dehydrogenase activities and available phosphorus content. No significant effects on sucrase activity and available nitrogen content were found by zoxamide. Vermicompost and soya bean cakes had lasting and outstanding performance in efficiently improving soil enzyme activity and N, P nutrition. The comprehensive understanding of the ecological impact induced by chiral pesticide enantiomers and fertilizers on soil is vital to ensure the sustainable development and safety of agricultural production. Graphical abstract: Image 1 Highlights: Fertilizers impact the selectivity for preferential dissipation of S -(+)-zoxamide. Zoxamide and fertilizers often cause soil acidification. Zoxamide shows negative effects on soil urease, dehydrogenase and available P. Vermicompost and soya bean cake better enhance soil enzyme activity, soil N and P.
