Herbicide pyrazosulfuron ethyl induces genotoxicity, cell cycle alterations and apoptosis in tilapia (Oreochromis mossambicus)

Aquaculture, Fish and Fisheries, 2022
Fishes are excellent subjects for the study of the mutagenic and carcinogenic potential of contaminants present in water. Herbicides are one of the toxic contaminants that cause lethal effects in fish.

Adaptation mechanism and tolerance of Rhodopseudomonas palustris PSB-S under pyrazosulfuron-ethyl stress [PDF]

BMC Microbiology, 2018
Background Pyrazosulfuron-ethyl is a long lasting herbicide in the agro-ecosystem and its residue is toxic to crops and other non-target organisms. A better understanding of molecular basis in pyrazosulfuron-ethyl tolerant organisms will shed light on ...

Effects of pyrazosulfuron-ethyl on caudal fin regeneration in zebrafish larvae

Ecotoxicology and Environmental Safety
With the widespread application of pesticides, water pollution problems are becoming more and more serious, which is very likely to cause harm to fish. Lower vertebrates, including fish, have the ability to repair damaged tissues.

Mechanism of Echinochloa crus-galli Resistance to the ALS-Inhibiting Herbicide Pyrazosulfuron-ethyl in China [PDF]

Plants
Rice (Oryza sativa L.) is a staple food crop, feeding more than 3.5 billion people. With the increasing demand for food in the 21st century, weed infestation poses the most significant biotic threat to global food security, and herbicides remain the most

Cytochrome P450s-Involved Enhanced Metabolism Contributes to the High Level of Nicosulfuron Resistance in Digitaria sanguinalis from China [PDF]

Biology, 2023
Large crabgrass (Digitaria sanguinalis (L.) Scop.) is one of the major malignant grass weeds in Chinese maize (Zea mays L.) fields, and it has recently developed resistance to the acetolactate synthase (ALS)-inhibiting herbicide nicosulfuron.

Photochemical degradation of pyrazosulfuron-ethyl in aqueous solution [PDF]

Journal of the Brazilian Chemical Society, 2013
This report describes photochemical behaviors of pyrazosulfuron-ethyl in aqueous solution. The photodegradation of pyrazosulfuron-ethyl for the first time was investigated in aqueous solution at two different irradiation wavelengths and pH values ranging from 2.00 to 10.00. Results show that the rate of photodegradation was faster in acidic medium than

Transformation Kinetics and Mechanism of the Sulfonylurea Herbicides Pyrazosulfuron Ethyl and Halosulfuron Methyl in Aqueous Solutions [PDF]

Journal of Agricultural and Food Chemistry, 2008
Pyrazosulfuron ethyl (PE) and halosulfuron methyl (HM) are two new highly active sulfonylurea herbicides that have been widely used for weed control in a variety of vegetables and other crops. These two herbicides have similar molecular structures, differing only in the substitutions on the pyrazole ring.
