“…Lavieille et al [58] demonstrated the utility of evaluating the stability of a pesticide towards sunlight when applied on crops, and highlighted the quick photolytic transformation of formulated mesotrione compared to pure mesotrione. In their study, the mesotrione rate of photolysis on leaves was much higher compared with data from the literature in water and on soils which implies that photolysis is likely to be a fast dissipation process on crops, as confirmed later by Barchanska et al [59]. Moreover, mesotrione on wax films imitating the surface of leaves is very reactive, with a DT 50 of photolysis of 2 h [60].…”

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.

“…The maximum concentration of AMBA (29 μg/L) was determined in March, and then it was slowly decreased to 18 μg/L at 6 months. This slow decrease in the AMBA concentration was due to the slow exchange of water between the pond and its tributaries and the highest stability of this compound in environment among all investigated triketones and their degradation products (Table 1; Barchanska et al 2016). MNBA was determined in water from the drainage ditch at a concentration of 147 μg/L (sample collected in April).…”

The aim of this study was to monitor the sediment, soil and surface water contamination with selected popular triketone herbicides (mesotrione (MES) and sulcotrione(SUL)), atrazine (ATR) classified as a possible carcinogen and endocrine disrupting chemical, as well as their degradation products, in Silesia (Poland). Seventeen sediment samples, 24 soil samples, and 64 surface water samples collected in 2014 were studied. After solid-liquid extraction (SLE) and solid phase extraction (SPE), analytes were determined by high-performance liquid chromatography (HPLC) with diode array detection (DAD). Ten years after the withdrawal from the use, ATR was not detected in any of the collected samples; however, its degradation products are still present in 41 % of sediment, 71 % of soil, and 8 % of surface water samples. SUL was determined in 85 % of soil samples; its degradation product (2-chloro-4-(methylosulfonyl) benzoic acid (CMBA)) was present in 43 % of soil samples. In 17 % of sediment samples, CMBA was detected. Triketones were detected occasionally in surface water samples. The chemometric analysis (clustering analysis (CA), single-factor analysis of variance (ANOVA), N-Way ANOVA) was applied to find relations between selected soil and sediment parameters and herbicides concentration. In neither of the studied cases a statistically significant relationship between the concentrations of examined herbicides, their degradation products and soil parameters (organic carbon (OC), pH) was observed.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-016-7798-3) contains supplementary material, which is available to authorized users.

“…In the soil, this herbicide can be absorbed by the roots of the plants and translocated via xylem and phloem. It presents water solubility of 28 g L -1 at pH = 7 and pK a = 3.2 (Barchanska et al, 2016). It is an herbicide from the triketone group and its mechanism of action is the inhibition of the enzyme 4-hydroxyphenyl-pyruvate-dioxygenase; it inhibits the formation of carotenoids, which are responsible for the protection against the excessive energy generated by the absorption of light into the leaf.…”

Sorption and Desorption of Tembotrione and its Metabolite AE 1417268 in Soils with Different Attributes

et al. 2019

Tembotrione is registered in Brazil for maize and is used in large areas of the country in each harvest. In recent years, producers have reported carryover effects of this herbicide in succeeding crops to maize. This fact can be attributed to tembotrione recommendations without knowing their interactions with tropical soils colloids. In this study, using high-performance liquid chromatography, it was possible to evaluate the influence of chemical and physical attributes on the sorption and desorption of tembotrione, as well as its metabolite AE 1417268, on seven soils from different regions of Brazil. The coefficients referring to sorption and desorption, as well as the hysteresis index (Kf, 1/n and H) of tembotrione and its metabolite were influenced by pH, clay content and organic matter. In soil samples with low levels of clay and organic matter, values of sorption coefficients were reduced as pH increased. The desorption of tembotrione and its metabolite in all soils were low, mainly in the clayey ones and in soils with higher organic matter content. The sorption of tembotrione and its metabolites varies with the attributes of soil, presenting a direct relation with clay and organic matter contents and an inverse one with soil pH. The desorption of tembotrione and its metabolite decreased with the increase in clay and organic matter contents in the evaluated soils.
