Short-time effects of herbicide nicosulfuron on biochemical activity of chernozem soil [PDF]

Journal of the Serbian Chemical Society, 2012
Short-time effects of the herbicide nicosulfuron on biochemical activity of soil was investigated. Nicosulfuron rates of 0.3, 1.5 and 3.0 mg/kg of soil were tested in a laboratory on chernozem soil.

Johnsongrass resistance to nicosulfuron

Advances in Weed Science
Abstract: Background Johnsongrass (Sorghum halepense (L.) Pers.) is one of the most problematic weeds worldwide, and in recent years, control failures with herbicides inhibiting the enzyme acetolactate synthase (ALS) have been reported. Objective Determine the resistance in different biotypes of Johnsongrass to nicosulfuron, as well as elucidate its ...

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, Volume 82, Issue 7, Page 5987-6009, July 2026.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Study on the effect of electrochemical treatment of nicosulfuron wastewater [PDF]

MATEC Web of Conferences, 2018
Nicosulfuron, a kind of sulfonylurea herbicide, because of its high activity and low dosage, has been widely used in corn planting weeding. Electrochemical method was chosen to treat its simulated waste water and the influence factors such as current intensity, plate spacing and electrolyte pH on electrolysis effect were investigated.
