Fitness costs associated with evolved herbicide resistance alleles in plants [PDF]

, 2009
Predictions based on evolutionary theory suggest that the adaptive value of evolved herbicide resistance alleles may be compromised by the existence of fitness costs.

Turfgrass species response exposed to increasing rates of glyphosate application [PDF]

, 2009
To investigate the response of nine turfgrass species exposed to increasing rates of glyphosate application, the dry matter production, visual leaf injury symptoms (e.g., chlorosis and necrosis) and the concentrations of shikimate and mineral nutrients ...

Genome-wide analysis of the Cannabis sativa cytochrome P450 monooxygenase superfamily and uncovering candidate genes for improved herbicide tolerance

Frontiers in Plant Science
Cannabis sativa is an economically important crop, yet weed management remains a significant challenge due to limited herbicide options. Cytochrome P450 enzymes play crucial roles in plant metabolism, including herbicide detoxification.

Cross-talk between cold and bispyribac-sodium on rice seedlings

Plant Stress, 2022
The shifting of rice planting date to early spring improved weed control, which is important to achieve high yield. However, early planting date exposes rice seedlings to cold stress, slowing crop establishment and affecting herbicide selectivity.

Can we predict community-wide effects of herbicides from toxicity tests on macrophyte species? [PDF]

, 2011
Macrophyte communities play an essential role in the way freshwater ecosystems function. It is thus of great concern to understand how environmental factors, especially anthropogenic ones, influence their composition and diversity.

Interaction of pre- and post-emergence herbicide treatment on efficacy of different black-grass biotypes with enhanced metabolism

Julius-Kühn-Archiv, 2014
In an outdoor container trial with different resistant black-grass biotypes with enhanced metabolism, efficacy of pre- and post-emergence treatments as well as their sequence was investigated in spring wheat.

Estimation of herbicide bioconcentration in sugarcane (Saccharum officinarum L.)

Ciência Rural, 2015
Sugarcane is an important crop for sugar and biofuel production in Brazil. Growers depend greatly on herbicides to produce it. This experiment used herbicide physical-chemical and sugarcane plant physiological properties to simulate herbicide uptake and ...

VERIFICATION OF THE MECHANISM OF GLYPHOSATE RESISTANCE IN ITALIAN RYEGRASS BIOTYPES [PDF]

Planta Daninha, 2016
The intense use of glyphosate for weed control led to the emergence of several cases of resistance to this herbicide. Weeds can survive the application of herbicides due to several factors, which may or may not be related to the herbicide site of action.
