Dactyloctenium aegyptium (L.) Willd. (Poaceae) Differentially Responds to Pre- and Post-Emergence Herbicides through Micro-Structural Alterations

open access: yesAgriculture, 2022
Herbicides are widely used to kill weeds and increase crop production all over the world. Nevertheless, some weeds show certain structural modifications in response to herbicide application that impart mostly partial or sometimes complete tolerance to ...

Evidence for an ecological cost of enhanced herbicide metabolism in Lolium rigidum [PDF]

open access: yes, 2009
1. In some cases, evaluation of resource competitive interactions between herbicide resistant vs. susceptible weed ecotypes provides evidence for the expression of fitness costs associated with evolved herbicide-resistant gene traits. Such fitness costs

Behaviour of pre-emergence herbicides in poplar nurseries

open access: yesForest Systems, 2002
The poplar cutting response to five pre-emergence herbicides (Oxadiazon, Isoxaben, Oxifluorfen, Tiazopir and Pendimetaline) in nursery conditions were studied. In order to evaluate quantitatively the selectivity and efficacy of the herbicides, the shoot height of the trees and the dry weight of the weeds were recorded. Species were identified and their
