“…According to Howard ( 1989 ), in a humus sandy soil, at pH 3.5, thiuram fully decomposes after 4 to 5 weeks. Rising pH to 7.0 extends that time above 14 weeks (Wauchope et al 1992 ; Sharma et al 2003 ; Sherif et al 2011 ). Thiuram degradation in soil is a complicated process governed by various factors of which moisture, organic content, and microbial activity are of main concern.…”

Basil (Ocimum basilicum L.) is extensively cultivated as either an important spice and food additive or a source of essential oil crucial for the production of natural phenylpropanoids and terpenoids. It is frequently attacked by fungal diseases. The aim of the study was to estimate the impact of thiuram contact time on the uptake of manganese, cobalt, nickel, copper, zinc, cadmium, and lead by Ocimum basilicum L. The relevant plant physiological parameters were also investigated. Two farmland soils typical for the Polish rural environment were used. Studies involved soil analyses, bioavailable, and total forms for all investigated metals, chlorophyll content, and gas exchange. Atomic absorption spectrometry was used to determine concentration of all elements. Analysis of variance proved hypothesis that thiuram treatment of basil significantly influences metal transfer from soil and their concentration in roots and aboveground parts. This effect is mostly visible on the 14th day after the fungicide administration. Thiuram modifies mycoflora in the rhizosphere zone and subsequently affects either metal uptake from the soil environment or their further migration within the basil plant. Notable, those changes are more evident for basil planted in mineral soil as compared to organic soil with higher buffering capacity.Electronic supplementary materialThe online version of this article (doi:10.1007/s11270-017-3508-0) contains supplementary material, which is available to authorized users.

“…The degradation of pesticides by microorganisms is gaining the extensive attention in the agricultural field and environmental microbiology. Interestingly, only few literatures are there which are dealing with the fungicide degradation by bacteria and in the previous years, many experiments have suggested that bacterial community are effective degraders of many different classes of fungicides: vinclozolin (Lee et al 2008 ), tubeconazole (Nicole et al 2009 ), captan (Megadi et al 2010 ), benzimidazole (Cycon et al 2011 ) and thiram (Sherif et al 2011 ) and is necessary since PCZ biodegradation was not thoroughly investigated with the exception of Sarkar et al ( 2009 ). Moreover, previously available reports are mentioned that PCZ utilization by microorganisms is not possible because of its ability to strongly adsorb with the soil’s organic matter (Kloskowski et al 1987 ; Ekler 1988 ; Woo et al 2010 ).…”

The isolation of propiconazole (PCZ) degrading bacterium BBK_9 strain was done from paddy soil, and it was identified as Burkholderia sp. based on the morphological characteristics and biochemical properties combined with 16S rRNA gene sequencing analysis. It has been seen that the factors such as temperature and pH influence the biodegradation process. The role of plasmid was studied in the degradation process by plasmid curing method. The PCZ acts as the sole carbon source and as energy substrate which can be utilized by the strain for its growth in Mineral salt medium and degraded 8.89 µg ml−1 of PCZ at 30 °C and pH 7 within 4 days. During the bioconversion process of PCZ, three metabolite were formed such as 1-(2,4-dichlorophenyl)-2-(1H-1,2,4-triazol-1-yl) ethanone, 1-[2-(4-chlorophenyl) ethyl]-1H-1,2,4-triazole and 1-ethyl-1H-1,2,4-triazole. The LD50 value of BBK_9 strain was determined with acridine orange which resulted in 40 µg ml−1 at cell density of 0.243 at 660 nm. Furthermore, plasmid curing was done using LD50 concentration and from that three plasmids got cured in the sixth generation. It was found that, cured strain was able to degrade 7.37 µg ml−1 of PCZ, indicating the plasmid encoded gene were not responsible for the PCZ degradation. On the source of these outcomes, strain BBK_9 can be used as potential strain for bioremediation of contaminated sites.

“…Certain environmental behavioral patterns of thiram has been reported, these include degradation Sherif et al, 2011), fate study (Sharma et al, 2011;Maznah et al, 2012), and photolysis (Filipe et al, 2013). Several research studies have been conducted to investigate the adsorption-desorption phenomena of thiram in soil, and results showed that a strong interaction existed between thiram and commercial humid acids, suggesting the relevance of organic matter on thiram sorption in soils (Filipe et al, 2009).…”

The present study was conducted in order to investigate the adsorption and desorption behavior of tetramethylthiuram disulfide (thiram) using the batch equilibration technique in two soil namely: Ultisols and Inceptisols. The adsorptiondesorption isotherms were expressed by the Freundlich equation. The adsorption isotherms of thiram was classified as L-type under Gile's classification. The Freundlich's adsorption coefficient (Kd) value for thiram in the Ultisols and Inceptisols soil were 3.78 and 2.10 mL g -1 , respectively. Results indicated that soil organic matter was the main factor affecting thiram behavior in the studied soils. The calculated total percentage desorption values from the Ultisols and Inceptisols soil after the fourth desorption process were 39.2% and 51.6%, respectively. The negative Gibb's free energy change (∆G°) values obtained suggest that thiram adsorption is an exothermic process. The effects of temperature (25, 30, and 35 °C) and soil pH (3, 7, 10) were also studied on adsorption of thiram in the test soils. Results showed that adsorption of thiram was not affected by temperature but clearly affected by soil pH.Key words: Thiram, adsorption, desorption, soil, temperature, pH.
