“…Our study highlighted that the estimated half-life of herbicide by HPLC was lower than that of bioassay ( Paul et al (2009), the half-lives of metsulfuron-methyl by HPLC and bioassay were found to be 6.3-7.8 and 17.5 days, respectively. The ability of a soil residual herbicide to have a phytotoxic effect on a sensitive crop depends on the half-life of the herbicide being used.…”

“…The pots were sub-irrigated as needed during the experiment. The plants were uprooted to measure the sulfosulfuron effects on plants root and shoot length at 15 days after planting (Paul et al, 2009). During the experiment, temperature and relative humidity were fluctuated between 18-25 °C and 58-85%, respectively.…”

“…After 15 days, all plants were uprooted and percentage root inhibition was calculated for each interval. Finally, the herbicide residues were determined under field conditions by fitting the data correspond to percentage root inhibition into the regression equation (Paul et al, 2009). …”

“…It has demonstrated that the herbicide residues are adsorbed tightly to soil particles with time, consequently the extraction technique is inadequate for detecting the residues. In contrast, the bound residues of herbicide can be released from the soil matrix during plant growth and thus the bioassay technique is more sensitive technique than HPLC and can detect more residues (Paul et al, 2009). The major advantage of the bioassay over the HPLC is, its relative simplicity.…”

Abstract. Sulfosulfuron, a new sulfonylurea herbicide, is used to control certain broadleaf and grass weed species in wheat fields. Herbicides, when applied to the field may leave unwanted residues in the soil. Bioassay and chemical assay techniques are main methods for monitoring herbicides levels in agricultural soils. Thus, a set of field and greenhouse experiments was established to evaluate the reliability and accuracy of HPLC and bioassay techniques to detect sulfosulfuron residues in the soil of the wheat field. The experiment was conducted in a randomized complete block design with three treatments in three replications for each treatment in 2014-2015 and 2015-2016 growing seasons at Marvdasht location. Herbicide treatments included: sulfosulfuron (apirus) at 26.6 and 53.2 g a.i. ha -1 rates and no-herbicide control. Herbicide was sprayed at the end of tillering stage of wheat in a field experiment. Samples were collected randomly with an auger from 0-10 cm depth at different times i.e. 0, 3, 10, 20, 30, 60, 90 and 125 days after herbicide spray. The bioassay experiment showed that root parameter was more sensitive to sulfosulfuron as compared with the shoot. According to the results, among the studied plants, garden cress was recognized as the most sensitive plant to different rates of sulfosulfuron herbicide. At recommended (26.6 g a.i. ha−1) and double (53.2 g a.i. ha -1 ) rates of application sulfosulfuron residues were detected up to 60 and 90 days after treatment by HPLC and bioassay techniques in both years, respectively. According to the bioassay and HPLC techniques at two rates of application, residues decreased with time in 2014 and 2015.

Metsulfuron methyl (MM) is a sulfonylurea herbicide used worldwide for the control of weeds in cereal crops. In a previous study, three Trichoderma strains (T5, T6, and T7) capable of using MM as a sole carbon and energy source were isolated. In this study, the three strains were identified as Trichoderma harzianum using genetic markers, and the transformation of MM by the T. harzianum strains was quantified using spectrophotometry. Solutions of different phytotoxic doses of MM were incubated with plugs of mycelia of the Trichoderma strains and the resulting mixtures were used to assess MM detoxification. The toxicity of the degradation products was tested with a bioassay using pre-germinated seeds of Lens culinaris Medik. and mycelia. Strain T7 was more efficient in transforming MM at higher concentrations than the T5 and T6 strains. In the bioassay, T5 showed the best performance at higher MM doses. We conclude that both T5 and T7 strains are promising for further studies regarding treatment or amelioration of MM contaminated soils.

Background Onion grass (Romulea rosea) is a common weed that infests native and improved pastures in the Mediterranean environments of southern Australia. It is a very challenging weed to control due to its distinctive growth and survival mechanisms involving corms. Methods Three glasshouse experiments were conducted in Australia to investigate the response of onion grass to defoliation and fertiliser application, the development and growth of onion grass corms and the chemical control of the weed in winter and spring. Results Defoliating consistently to 1 cm above ground reduced corm weight by 84% compared with the control. Medium or high fertiliser application did not increase herbage mass of onion grass compared with the nonfertilised treatment. The corm weight of onion grass declined from Weeks 1 to 8 after emergence, remained at 53–60 mg dry matter (DM) corm−1 from Weeks 8 to 19 and then declined on average to 37 mg DM corm−1 up to Week 26 after emergence. New corms started to develop at Week 6 after emergence. A small proportion of the onion grass plants (7.5%) developed multiple new corms (3–6 corms) from a single old corm. The most effective herbicide control was a winter application of metsulfuron methyl or imazamox as an alternative product to protect clover. Conclusions This study has identified the growth and development patterns of onion grass corms, how the plant responded to defoliation and fertiliser application and effective chemical control of this weed. These findings have significant practical implications for the improvement of onion grass‐infested pastures.

Abstract: Lentil seed bioassay is a more sensitive technique than HPLC. Traces of residues detected in subsurface soil indicated the mobility of metsulfuron-methyl into lower layers.
