“…Application of tebuconazole in both the experimental years at 10FR considerably reduced the FDHA activity until the harvest time as compared to the control treatments. The decrease in FDHA due to tebuconazole application at 10FR may be related to the reduction in soil microbial biomass as well as the inhibitory effect of tebuconazole on the synthesis of the enzymes involved in FDHA hydrolysis (Verdenelli et al 2012;Sułowicz and Piotrowska-Seget 2016). Pal et al (2008) reported a transitory toxic effect of fungicide pencycuron on FDHA activity particularly at lower doses, whereas the effects were slightly longer at higher concentrations (10 times the field rate).…”

Field experiments in peanut (Arachis hypogaea L.) soil ecosystem were conducted during the summer seasons (February-June) of the year 2013 and 2014 in black clay soil treated with tebuconazole at field rate (FR), 2-times FR (2FR) and 10-times FR (10FR) as foliar spray to determine the impact of tebuconazole on soil microbial properties and enzymatic activities. Tebuconazole application at FR and 2FR resulted in a short-lived and transitory toxic effect on soil microbial properties and enzymatic activities. The duration of this disturbance was slightly longer at 10FR. Incorporation of tebuconazole in soil resulted in stimulating the soil microbial activity as evidenced by increased ammonification and nitrification rates and increased soil microbial biomass at later stage. However, it was more toxic to soil ergosterol which is the indicator of the presence of viable fungi. Soil enzymatic activities like fluorescein diacetate-hydrolyzing activity, urease, phosphatase and aryl sulfatase are either unaffected or shortly inhibited and then recovered. However, dehydrogenase and nitrate reductase activity decreased more drastically and can be used as valuable indicator to assess the impact of tebuconazole application on soil health. The results indicated that instead of single assays, a broad spectrum analysis of soil microbial and enzymatic activities gives a better insight about the impacts of pesticide on soil health. From this study, it is also concluded that the application of tebuconazole at 10FR had adverse effects on the microbial variables and the effect on long-term application should be studied further.

“…In this study, although soil bacterial and actinomycete numbers were drastically depressed, no significant effects on fungal population were also observed. This may be due to the lower pH value of the soil (pH = 5.22), which promotes fungal growth [24]. So, the responses of soil microbial communities to fungicides were dependent on soil characteristics.…”

“…One of the compounds which is used to replace ineffective fungicides is a next generation DMI fungicide—triazole tetraconazole. The impact of tetraconazole on the soil environment is poorly studied and these data are mainly provided by the producers of the fungicide and two field study (Zhang et al 2014a ; Sułowicz and Piotrowska-Seget 2016 ). Microbial degradation, hydrolysis and photolysis proceed slowly in soil.…”

Effect of the fungicide tetraconazole on microbial community in silt loam soils from orchard with long history of triazole application and from grassland with no known history of fungicide usage was investigated. Triazole tetraconazole that had never been used on these soils before was applied at the field rate and at tenfold the FR. Response of microbial communities to tetraconazole was investigated during 28-day laboratory experiment by determination of changes in their biomass and structure (phospholipid fatty acids method—PLFA), activity (fluorescein diacetate hydrolysis—FDA) as well as changes in genetic (DGGE) and functional (Biolog) diversity. Obtained results indicated that the response of soil microorganisms to tetraconazole depended on the management of the soils. DGGE patterns revealed that both dosages of fungicide affected the structure of bacterial community and the impact on genetic diversity and richness was more prominent in orchard soil. Values of stress indices—the saturated/monounsaturated PLFAs ratio and the cyclo/monounsaturated precursors ratio, were almost twice as high and the Gram-negative/Gram-positive ratio was significantly lower in the orchard soil compared with the grassland soil. Results of principal component analysis of PLFA and Biolog profiles revealed significant impact of tetraconazole in orchard soil on day 28, whereas changes in these profiles obtained for grassland soil were insignificant or transient. Obtained results indicated that orchards soil seems to be more vulnerable to tetraconazole application compared to grassland soil. History of pesticide application and agricultural management should be taken into account in assessing of environmental impact of studied pesticides.Electronic supplementary materialThe online version of this article (doi:10.1007/s10646-016-1661-7) contains supplementary material, which is available to authorized users.
