“…However, Borowik et al (2017) and Kacynski et al (2016) have reported that mesotrione applied in herbicide mixtures of mesotrione + terbuthylazine + S-metolachlor and mesotrione + S-metolachlor inhibit DHA when the herbicides are applied at doses higher than the recommended field rate. It has been reported accordingly that the application of herbicides mixtures to soil can inhibit DHA (Kacynski et al, 2016;Wyszkowska et al, 2016).…”

Certain agricultural practices, such as the repeated application of herbicides or organic amendments to soil, can influence herbicide dissipation. This research has studied the effects of two repeated applications of mesotrione, pethoxamid, and triasulfuron on their dissipation rates in unamended soil (S) and soil amended with green compost (S+GC) or sewage sludge (S+SS). The dissipation experiment has also included an evaluation of the adsorption of the three herbicides by soils and of changes in soil dehydrogenase activity (DHA). The adsorption of the three herbicides by amended soils (Kf range 0.83-2.98) was higher than by unamended soil (Kf range 0.20-0.64). The adsorption coefficients (Kd) of mesotrione and triasulfuron were higher for S+SS, while that of pethoxamid was higher for S+GC, but no relationship between values for the time to 50% degradation (DT) and adsorption coefficients could be determined. The repeated application of mesotrione decreased its dissipation rate in unamended soil (DT increased from 4.75 to 8.15 days) and amended soils (DT increased from 11.7 to 28.2 days in S+GC and from 17.7 to 37.9 in S+SS), whereas the repeated application of pethoxamid increased its dissipation rate in all the treatments, and the rate for triasulfuron increased only in amended soils. The highest DT values for pethoxamid (12.3 days) and triasulfuron (57.1 days) were in S+GC, and the lowest in S+SS (8.35 and 24.7 days). Soil DHA was stimulated by the presence of GC in the soil and by the first application of mesotrione. The second application of mesotrione and pethoxamid positively affected soil DHA, but this did not occur for triasulfuron. The repeated applications of herbicides and soil organic amendments have different effects on herbicide dissipation, adsorption, and soil DHA, and they should be taken into account when assessing soil quality and other potential environmental implications of pesticide use.

“…4B, C). In similar studies, a negative effect on the structure of microorganisms affecting Actinobacteria was stated after the application of a mixture of pethoxamid and terbuthylazine (Wyszkowska et al, 2016). Also, it has been indicated a significant early impact and a relevant late impact on the bacterial community when the application of pethoxamid and glyphosate to soil was carried out (Valverde et al, 2014).…”

“…The most significant effect was a DHA peak value observed after the herbicide's application at the rate of 50 mg kg -1 in S+GC. Wyszkowska et al (2016) have reported a strong inhibition of soil DHA when a mixture of pethoxamid and terbuthylazine is applied at rates higher than 14.63 mg a.i. kg -1 soil, regardless of the length of the assay.…”

Highlights The effect of pethoxamid doses and amendments on soil microbial community was evaluated. The dissipation rate of pethoxamid decreased with the dose applied. Organic amendments accelerated the dissipation of higher doses of pethoxamid.  Higher soil dehydrogenase activity values are close to the half-life of herbicide. Effects of pethoxamid dose on soil microbial structure were recorded in amended soils.

The intensive and extensive application of imidacloprid in agriculture has resulted in water pollution and risks to aquatic invertebrates. However, pure bacteria remediation of imidacloprid in surface water environments has not been studied. Here, we isolated an imidacloprid-degrading bacterium from a water environment, examined its imidacloprid degradation in pure culture and surface water, sequenced its genome, and compared its Clusters of Orthologous Groups (COG) protein categorization with that for another imidacloprid-degrading bacterium. The isolate was an obligate oligotrophic bacterium, Hymenobacter latericoloratus CGMCC 16346, which degraded imidacloprid via hydroxylation by co-metabolism in pure culture. Resting cells degraded 64.4% of 100 mg/L imidacloprid in 6 days in the presence of co-substrate maltose, and growing culture degraded 40.8% of imidacloprid in 10 days. H. latericoloratus CGMCC 16346 degraded imidacloprid in surface water without co-substrate supplementation and retained imidacloprid-degrading activity after 30 days. The half-life of imidacloprid in surface water was decreased from 173.3 days in the control to 57.8 days by CGMCC 16346 inoculation. Genome sequencing and COG analysis indicated that carbohydrate metabolism and transport, cell wall/membrane biogenesis, and defense mechanisms are enriched in H. latericoloratus CGMCC 16346 compared with the copiotrophic imidacloprid-degrading Pseudoxanthomonas indica CGMCC 6648, indicating that H. latericoloratus CGMCC 16346 is adapted to live in oligotrophic water environments and biofilms. H. latericoloratus CGMCC 16346 is a promising bioremediation agent for elimination of imidacloprid contamination from surface water.
