“…The significant difference of the micronuclei frequency between the control and cells exposed to NaCl indicates the sensitivity and the reliability of this test system. Such sensitivity of V. faba roots was also caused by a wide range of other stress conditions such as heavy metal treatments (Souguir et al, 2008(Souguir et al, , 2011Yi et al, 2010), olive mill waste water (El Hajjouji et al, 2007), pesticides (Sta et al, 2012), and diesel exhaust particulate matter (Corrˆea et al, 2016). Recently, an interlaboratory study of seven laboratories from three countries, investigating the robustness of this test for soil or soil materials assessment, confirmed its applicability based on the international ISO 29200 protocol (Cotelle et al, 2015).…”

“…Several studies show that the micronucleus assay is an effective technique to assess genotoxic damage caused by toxic substances. The rate of the micronucleus is usually used to assess the genotoxicity of contaminated soil, sediment, organic material, water, and industrial effluent (Corrˆea et al, 2016;Cotelle et al, 2015;Renjana et al, 2013;Sta et al, 2012). The most frequently used plant species to test both clastogenic and aneugenic effects is Vicia faba.…”

Despite the well-known toxic effect of chloride sodium (NaCl), only few studies analyze its genotoxic effect on crops. Micronucleus assay is an efficient tool for the measure of chromosomal DNA damages. Based on this test, the effects of salt on micronucleus induction, and on chromosome and nucleus changes, were investigated in Vicia faba root tips treated with NaCl (electrical conductivity = 25 dS/m) during 24 hours. V. faba meristematic cells showed a significant increase in the number of micronuclei compared with the control. Micronucleus size varied from small to large and appeared at different stages of mitosis. Moreover, different chromosomal aberrations like breaks, bridges, rings, vagrant, and lagging chromosomes, were observed in the metaphase, the anaphase, and the telophase. In addition, nuclear alterations in the interphase were characterized by the presence of binucleated cells, strap nuclei with lesions, hyperchromasia, buds, and nuclei with irregular shapes and lesions.

Effect of Adjuvants and pH Adjuster on the Efficacy of Sulcotrione Herbicide

et al. 2020

The effectiveness of herbicides is affected by the pH of the spray liquid. The use of adjuvants can mitigate the negative effect of pH, and it also allows for a reduction in herbicide doses while maintaining high efficiency. Greenhouse studies were performed to evaluate the efficacy of the herbicide sulcotrione (HRAC F2), against barnyardgrass, at full or reduced doses with adjuvants, and a modified pH of the solutions. The contact angle and surface tension of liquid spray drops, as well as the shear viscosity of individual solutions, were also tested. Results indicated that at a low pH of the spray liquid (4), the use of a reduced dose of sulcotrione with adjuvant based on methylated rapeseed oil can increase the effectiveness of barnyardgrass control to the same level as at the full dose of herbicide. The use of adjuvants contributed to the reduction in the contact angle and the surface tension of liquid spray droplets. No significant differences in shear viscosity were observed for individual solutions.

“…This suggests that degradation products enhanced microtubule disruption whereas sulcotrione did not. The genotoxic effect of sulcotrione previously described [18] could be triggered by oxidative stress, leading to generation of free radicals and alterations in antioxidative or free radical scavenging enzyme systems [19][20][21]. We show that degradation of sulcotrione was correlated to decrease of mitotic index, and to increase of anomaly and c-mitosis frequencies.…”
