“…Furthermore, a high level of linearity was observed in the unamended soil by the pethoxamid adsorption curve (n f = 1,68), whereas its sorption by amended soil was near to the linearity of (C-type) (Pose-Juan et al, 2018). Dimethenamid-p showed the lowest K f values in the studied soils and was relatively smaller than the value in PPDB (2019), (K f =3.69 cm 3/n µg 1 − 1/n g − 1 ) Kočárek et al (2018). also reported a small sorption value (K f = 2.12 cm 3/n µg 1 − 1/n g − 1 ) for dimethenamid-p in silt loam soil.Westra et al (2015) examined dimethenamid-p sorption in 25 different soils and the mean K d values calculated for soils were 2.3 cm 3 g − 1 .…”

“…In terms of K f parameters, our ndings are in agreement with those shown by Wauchope et al (1992) and Rytwo et al (2005), which addressed the strong a nity of pendimethalin to solid phases due to its hydrophobic nature. Kočárek et al (2018) previously studied sorption isotherms of pendimethalin under laboratory conditions and obtained a higher K f value (270.1 cm 3/n µg 1 − 1/n g − 1 ) in a silt loam soil. Aclonifen showed signi cantly lower K f values than that shown in PPDB (K f = 138.1 cm 3/n µg 1 − 1/n g − 1 ).…”

“…Dimethenamid-p is characterized as having low volatility, high solubility in water, and is non-persistent in soil environments (PPDB 2019). It has a calculated DT 50 value of about 11.1 days in Haplic Chernozem under eld conditions (Kočárek et al 2018).The aim of this research was: (i) to characterize the adsorption and degradation of herbicides in three soils concerning different properties; (ii) identify main soil parameters that in uence adsorption and degradation employing a correlation analysis, and (iii) to establish how the degradation and sorption processes…”

This study focuses on the assessment of herbicide adsorption and degradation in three soils (Haplic Chernozem, Haplic Fluvisol, and Arenic Regozem) from different agricultural regions of the Czech Republic where sunflower is cultivated. Soil samples were used in laboratory batch sorption and degradation experiments for six herbicides commonly used on sunflower crops. The findings are used to examine the effect of soil and herbicide properties on adsorption and degradation, as well as to determine the possible relation between the two processes. The (Kf) sorption coefficient ranged from 1.07 to 135.37 cm3/n μg1-1/n g-1, and sorption increased in order: dimethenamid-p < pethoxamid < s-metolachlor < flurochloridone < aclonifen < pendimethalin. Sorption of all six herbicides was positively correlated with organic matter content (p < 0. 001), and cation exchange capacity (p < 0.001). pH was negatively correlated with the sorption of all six compounds (p < 0.001). Degradation rates of herbicides ranged from 0. 012 to 0. 048 day-1, which corresponding to (DT50) half-lives between 14 - 57 days respectively. The longer half-lives were always found in Haplic Fluvisol with higher organic matter content. Results showed that both adsorption and degradation of herbicides is mainly controlled by soil organic matter. A negative relationship was found between the sorption coefficient and the rate of degradation. It can be concluded that the Freundlich sorption coefficient (Kf) can be a good predictor for soil degradation of the studied herbicides.

“…However, there are many different types of adjuvants and based on some factors including herbicide classes, plant species, and environmental conditions, the response to the presence of adjuvants in spray solution could be evaluated. Reduction of surface tension of spray solution, the bioavailability of the herbicide molecules and improve the distribution pattern and contact angle of herbicides, as well as the increase of droplets spread on plant surface and enhance the foliar activity of post-emergence herbicides could be achieved by addition of adjuvants to herbicides solution (Rashed-Mohassel et al, 2009;Calore et al, 2015;Kočárek et al, 2018;Niedobová et al, 2019). However the adjuvant efficiency depends on the herbicide, adjuvant and target plant relationships (Bunting et al, 2004).…”

Environmental risks resulting from the increasing application of chemical herbicides have raised many concerns about human health and the safety of agro ecosystems and environment. Hence, it is very important to find practical and effective methods for reducing the use of pesticides in environment as well as the increasing the efficiency of these compounds. Addition of adjuvants to spray solutions could be considered as one of these methods. Greenhouse studies were conducted using a complete randomized design with a factorial arrangement during 2015-2016 to evaluate the impact of different adjuvants (citogate, canola oil, and castor oil) at concentrations of 0.1 and 0.2 (%v/v) with 5, 10, 20, 30 and 40 g a.i. ha -1 of tribenuron methyl herbicide to control common lambsquarters. Results showed that all applied adjuvants enhanced the efficacy of tribenuron methyl in decreasing the biomass of common lambsquarters. Efficacy of this herbicide increased with enhancing its concentrations. The required dose of herbicide to give 50 per cent common lambsquarters control (ED50) for no adjuvant, citogate, castor oil, and canola oil application (0.2 (%v/v)) was 21.24, 11.48, 11.65, and 11.81 g a.i. ha -1 , respectively. Totally the application of citogate and canola oil had the highest and the lowest impact on tribenuron methyl performance to control of common lambsquarters respectively. Also, the Relative Potency values were significantly increased when adjuvants were added to this herbicide. The results revealed that the use of citogate and vegetable oils can increase the efficiency tribenuron methyl, and reduce the application rate of this herbicide in agro ecosystems.
