Effects of ecotoxicity of penoxsulam single and co-exposure with AgNPs on Eisenia fetida
Chemosphere, 2022Penoxsulam (PNX) and silver nanoparticles (AgNPs) are likely to coexist in soils due to continuous use. However, the ecotoxicity of PNX in earthworms and the effect of AgNPs on PNX toxicity are unknown. Therefore, the toxicity of PNX (0.05, 0.5, and 2.5 mg/kg) single and co-exposure with AgNPs (10 mg/kg) after 28 and 56 days on Eisenia fetida (E ...

Thiobencarb and Penoxsulam Residues in Some Fresh Water Fish
Alexandria Journal of Veterinary Sciences, 2020The present study was concluded to throw light on detection of thiobencarb and penoxsulam residues in some fresh water fish. The examined fish samples were collected randomly from different farms in Kafr El Sheikh Governorate, Egypt at the time as fresh samples (50 of each Tilapia and Cat fish samples), The samples were placed in plastic bags then ...

Microbial Degradation of Penoxsulam in Flooded Rice Field Soils
Journal of Agricultural and Food Chemistry, 2006The degradation of penoxsulam [2-(2,2-difluoroethoxy)-N-5,8-dimethoxy[1,2,4]triazolo[1,5-C]pyrimidin-2-yl-6-(trifluoromethyl)benzene-sulfonamide] was studied in flasks simulating flooded rice field conditions using four representative rice field soils from the Sacramento Valley.

Echinochloa phyllopogon, a malignant weed found in paddy fields, has developed resistance to many acetolactate synthase-inhibiting herbicides. This resistance threatens the effectiveness and sustainability of herbicides. Glutathione S-transferases (GSTs) are important detoxification enzymes responsible for herbicide resistance in plants.

Mechanism of Resistance to Penoxsulam in Late Watergrass [Echinochloa phyllopogon (Stapf) Koss.]
Journal of Agricultural and Food Chemistry, 2009Late watergrass [ Echinochloa phyllopogon (Stapf.) Koss.] is a major weed of California rice that has evolved P450-mediated metabolic resistance to multiple herbicides. Resistant (R) populations are also poorly controlled by the recently introduced herbicide penoxsulam.

Urea Ammonium Nitrate Effects on Bispyribac and Penoxsulam Efficacy
Weed Technology, 2008Experiments were conducted at the Lonoke Extension and Applied Research Center greenhouse at Lonoke, AR, to evaluate the effects of urea ammonium nitrate (UAN) on bispyribac and penoxsulam efficacy on barnyardgrass, hemp sesbania, and broadleaf signalgrass. Herbicide treatments included bispyribac at 17.9 or 35.8 g ai/ha or penoxsulam at 24.4 or 48.9 g

Influence of Flood Interval and Cultivar on Rice Tolerance to Penoxsulam
Weed Technology, 2008Studies were conducted in 2003 and 2004 over seven environments evaluating rice root growth inhibition (RGI) and foliar injury from penoxsulam at 30 and 60 g ai/ha and bispyribac-sodium at 30 g ai/ha applied to four- to five-leaf rice at three flood timings, 1, 7, and 14 d after herbicide treatment (DAT), for five rice cultivars, ‘Bengal’, ‘Cypress ...

Toxic Effects of Penoxsulam Herbicide in Two Fish Species Reared in Southern Brazil
Bulletin of Environmental Contamination and Toxicology, 2013Toxic effects of penoxsulam herbicide on acetylcholinesterase, thiobarbituric acid-reactive substances and protein carbonyl were studied in silver catfish (Rhamdia sp.) and carp (Cyprinus carpio). Acetylcholinesterase activity was inhibited in both brain and muscle tissue, with the inhibition being greater in carp than in silver catfish.

Penoxsulam evaluation for weed control efficacy and increased rice yield
Indian Journal of Weed Science, 2017Field experiments were conducted for two years at wetland farm, Tamil Nadu Agricultural University, during Kharif seasons of 2014 and 2015 (June to October) to evaluate the penoxsulam (21.7% SC) for weed control in rice. Based on two years data, it was found that pre-emergence application of penoxsulam 22.5 g/ha resulted in significantly lower total ...
