Effects of atrazine and nicosulfuron on freshwater microalgae

open access: yesEnvironment International, 2001
Growth modifications caused by various concentrations of atrazine and nicosulfuron were monitored in closed and continuous culture of Chlorella vulgaris (chlorophyta), Navicula accommoda (diatomophyta), and Oscillatoria limnetica (cyanophyta). The concentration at which algal growth rate was reduced twofold (EC50) was determined in the three species ...

) control using nicosulfuron in corn [PDF]

open access: yes, 2023
Weed control in corn is a major challenge due to increasing problems with highly dominant weed species and herbicide resistance evolution. Common lambsquarters and johnsongrass constitute up to 80% to 90% of the weed population in many spring crops ...

The outlet design of flat fan nozzle varies the application time of day effect on nicosulfuron activity

open access: yesAgraarteadus, 2021
On two container-grown species, johnsongrass and velvet­leaf, nicosulfuron was sprayed with the Anti-Drift Single, Dual, and Triplet Flat-Fan nozzles (AD/S, AD/D, AD/T nozzles, respectively) at 05:00 to 21:00, with a two-hour interval.

Hydrolysis of nicosulfuron under acidic environment caused by oxalate secretion of a novel Penicillium oxalicum strain YC-WM1

open access: yesScientific Reports, 2017
A novel Penicillium oxalicum strain YC-WM1, isolated from activated sludge, was found to be capable of completely degrading 100 mg/L of nicosulfuron within six days when incubated in GSM at 33 °C.

The response of weedy sunflower (Helianthus annuus L.) to nicosulfuron: An examination of vegetative parameters and acetolactate synthase activity [PDF]

open access: yesArchives of Biological Sciences, 2019
Genetic and morphological interpopulation variability of weed species is often responsible for variable responses to herbicides. As weedy sunflower, an invasive form of Helianthus annuus L., possesses high morphological and genetic variability, very ...
