“…This has been supported by another study (EFSA 2010). Microorganisms are also a dominant factor in the degradation of difenoconazole in soil, and high soil moisture content inhibits microbial activity (Rueegg and Siegfried 1996;Wang et al 2009). High soil organic carbon content increases microbial activity (Ghosh and Singh 2009).…”

Residues of a fungicide suspension (12 % difenoconazole, 18 % azoxystrobin) in bananas and soil were studied under tropical and subtropical monsoon climates, in Hainan and Yunnan provinces, respectively. The half-lives in bananas were shorter in Hainan (difenoconazole: 8.4-10.7 days; azoxystrobin: 7.8-8.4 days) than Yunnan (difenoconazole: 11.3-13.0 days; azoxystrobin: 10.4-11.6 days), possibly because of the higher temperatures and solar radiation levels in Hainan. The half-lives in soil were shorter in Yunnan (difenoconazole: 15.5-16.7; azoxystrobin: 11.9-13.9 days) than Hainan (difenoconazole: 23.1-23.2 days; azoxystrobin: 16.0-16.1 days), possibly because the organic carbon content was higher and rainfall lower in Yunnan than Hainan. Their physico-chemical properties suggest difenoconazole and azoxystrobin should be stable in bananas and soil, but both decreased to safe concentrations by the minimum harvest time after spraying the mixture at the recommended dosage and 1.5 times that dosage, through physical, chemical, and biological processes.

It was recrystallized from am ethyl tert. butyle ther solution at room temperature to give colourless crystals suitable for single-crystal X-ray diffraction. Experimental detailsHa toms were positioned geometrically with C-H =0 .93, 0.97 and 0.96 Åfor aromatic, methylene and methyl, respectively, and constrained to ride on their parent atoms, with U iso (H) =1.2 (1.5 for methyl)times U eq (C). Difenoconazoleisanimportant representative of atriazole derivative, which has been used as the most efficient triazole fungicide [5,6]. But alot of waste residues are formed in the process of production. In order to get deeper insight into the reaction mechanism and to optimize the production process, the title compound wass eparated andi ts structure was characterized. As shown in thefigure,fourrings exist in the molecular structure. Two benzene rings and triazol ring are planar, while the dioxolan ring is bent. The dihedral angle between two benzene rings is 80.6°ow-ing to rotating and bending of the ether bond. The dioxolan ring adopts an envelope conformation, with the C17 atom deviating from the C18/O2/C13/O3 plane by 0.248(2) Å.Z. Kristallogr.
