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

Johnsongrass resistance to nicosulfuron
Advances in Weed ScienceAbstract: 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 ...
