“…The higher dissipation rate of triasulfuron at higher doses in S might be attributed to a saturation of adsorption sites and a higher bioavailability of the herbicide to be degraded, as observed for other pesticides (Papadopoulou et al, 2016). However, a decrease in the dissipation rate was also reported when the dose of herbicide increased from 20 to 1000 μg kg -1 for triasulfuron (Menne and Berger, 2001) and for other pesticides applied at increasing doses (Vischetti et al, 2000; El-Ghamry et al, 2002; Muñoz-Leoz et al, 2013; Pose-Juan et al, 2015b). The lower pesticide dissipation rate was attributed to the reduced capacity of soil microbial communities to biodegrade them, variations in microbial biomass, and the pesticide’s toxicity for the soil microbial community.…”

“…It has been noted that amendments have a stimulating effect on soil microbial biomass, acting as additional carbon and energy sources (Grenni et al, 2009; Pose-Juan et al, 2015a) and providing additional microorganisms that could affect community dynamics. Furthermore, SS with a lower C:N ratio might be rich in nutrients due to its rapid decomposition, giving rise to higher microbial biomass values (Singh et al, 2016).…”

“…Changes in soil biodiversity could affect crop yields, nutrient cycling, soil fertility, bioremediation capacity, soil formation and structure, etc., which should be avoided to ensure soil protection (European Commission [EC], 2006). There is limited information about the effect of agricultural practices involving the application of organic amendments and pesticides on microbial communities and/or soil biodiversity (Scelza et al, 2008; Rodríguez-Liébana et al, 2014; Pose-Juan et al, 2015a,b; Singh et al, 2016). Further investigation is required to evaluate the impact these agricultural management practices have on soil conservation and maintenance in order to prevent its degradation.…”

“…Other studies have addressed the changes in soil microbial structure and diversity after pesticide and organic residue application (Singh et al, 2014; Feld et al, 2015; Pose-Juan et al, 2015a; Álvarez-Martín et al, 2016). However, information is limited on the abundance and performance of soil microbial communities following the simultaneous application of pesticides and organic residues, due to the large number of pesticides and organic residues used in agriculture.…”

The effect of organic amendments and pesticides on a soil microbial community has garnered considerable interest due to the involvement of microorganisms in numerous soil conservation and maintenance reactions. The aim of this work was to assess the influence on a soil microbial community of the simultaneous application of the herbicide triasulfuron at three doses (2, 10, and 50 mg kg-1), with an organic amendment [sewage sludge (SS) or green compost (GC)]. Dissipation kinetics, soil microbial biomass, dehydrogenase activity (DHA) and respiration, and the profile of phospholipid fatty acids (PLFAs) extracted from the soil, were determined in unamended (S) soil and amended (S+SS and S+GC) ones. Triasulfuron dissipation followed the single first-order kinetics model. Half-life (DT50) values were higher in the amended soils than in the unamended one for the 10 and 50 mg kg-1 doses. The dissipation rates were lower in the S+GC soil for the three herbicide doses applied. In general, soil biomass, DHA and respiration values increased in SS- and GC-amended soils compared to the unamended one. DHA values decreased (S and S+SS) or increased (S+GC) with the incubation time of soil with herbicide at the different doses applied. Respiration values increased with the herbicide doses applied and decreased with the incubation time, although maximum values were obtained for soils treated with the highest dose after 70 days of incubation. PLFA analysis indicated different effects of triasulfuron on the soil microbial community structure depending on the organic amendments. While the increasing triasulfuron doses resulted in deeper alterations in the S soil, the time after triasulfuron application was the most important variation in the S+SS and S+GC soils. The overall results indicate that the soil amendment has an effect on herbicide dissipation rate and the soil microbial community. Initially, a high dose of triasulfuron had detrimental effects on the soil microbial community, which is important in the case of the long-term use of this compound.

Mesotrione (2‐[4‐(methylsulfonyl)‐2‐nitrobenzoyl]‐cylohexane‐1,3‐dione) is an herbicide brought to the market 15 years ago and commonly used on maize cultures. This review summarizes the results obtained from worldwide scientific studies on its efficiency, effects, and fate in environment, in order to bring first overall conclusions about its safety of use. The comprehensive review of the available scientific literature reveals that mesotrione applied as recommended ensures the desired effects on sensitive crops, mainly in post‐emergence application, while exhibiting favorable toxicological, and environmental profile. According to the studies realized so far, mesotrione presents no significant risks to humans and other non‐target organisms or to the environment. Its degradation by soil microorganisms is fast, ensuring a low possibility to retrieve mesotrione in ground water. Its terminal residues in soil, maize, grain, and maize straw are below the limit of quantification. All these results suggest that mesotrione applied as directed ensures the respect of current environmental standards and food safety. Future prospects should focus on its associated pesticides when applied in mixtures on field, and on the detection, quantification, and risk assessment of its transformation products in order to exclude any toxicological synergistic effects.

BACKGROUND The purpose of the present study was to develop ecofriendly herbicide formulations. Its main aim was to develop and investigate slow‐release formulations of herbicides (metribuzin, tribenuron‐methyl, and fenoxaprop‐P‐ethyl) of different structure, solubility, and specificity, which were loaded into a degradable matrix of poly‐3‐hydroxybutyrate (P(3HB)) blended with available natural materials (peat, clay, and wood flour). RESULTS Differences in the structure and physicochemical properties of the formulations were studied depending on the type of the matrix. Herbicide release and accumulation in soil were associated with the solubility of the herbicide. Fourier‐transform infrared spectroscopy showed that no chemical bonds were formed between the components in the experimental formulations. Degradation of the formulations in agro‐transformed soil in laboratory conditions was chiefly influenced by the shape of the specimens (granules or pellets) while the effect of the type of filler (peat, clay, or wood flour) was insignificant. The use of granules enabled more rapid accumulation of the herbicides in soil: their peak concentrations were reached after 3 weeks of incubation while the concentrations of the herbicides released from the pellets were the highest after 5–7 weeks. Loading of the herbicides into the polymer matrix composed of the slowly degraded P(3HB) and natural materials enabled both sustained function of the formulations in soil (lasting between 1.5 and ≥3 months) and stable activity of the otherwise rapidly inactivated herbicides such as tribenuron‐methyl and fenoxaprop‐P‐ethyl. CONCLUSION The experimental herbicide formulations enabled slow release of the active ingredients to soil. © 2019 Society of Chemical Industry
