Experimental evolution of herbicide resistance in chlamydomonas reinhardtii [PDF]

Our understanding of the evolutionary dynamics of selection for herbicide resistance is limited by the time and space required to conduct meaningful selection experiments in higher plants. This constrains the study of the

Herbicide Resistance

, 1991
Herbicide resistance is defined as "the inherited ability of a plant to survive a dosage of a herbicide to which the wild population is sensitive". Weeds that are resistant to specific herbicides have become dominant members of field populations in many ...

Inheritance and molecular characterization of resistance to AHAS-inhibiting herbicides in rapeseed

Journal of Integrative Agriculture, 2017
Rapeseed is a very important oil crop in China; however, its production is challenging due to the absence of effective weed management strategies. This is predominantly because of a shortage of herbicide resistance genes. Acetohydroxyacid synthase (AHAS)

Incidence of resistance to ALS and ACCase inhibitors in Echinochloa species and soil microbial composition in Northern Italy

Scientific Reports
The increasing amount of weeds surviving herbicide represents a very serious problem for crop management. The interaction between microbial community of soil and herbicide resistance, along with the potential evolutive consequences, are still poorly ...

Computer Vision for Site-Specific Weed Management in Precision Agriculture: A Review

Agriculture
Weed management is always a challenge in crop production, exacerbated by the issue of herbicide resistance. Excessive herbicide application not only leads to the development of herbicide resistance weeds but also causes environmental problems.

Herbicide Resistance Update

, 1998
Although herbicides have been an important component oflowa crop production for more than 30 years, the degree of reliance on these ag chemicals has increased significantly in the past decade.

How Does Herbicide Resistance Change Farmer’s Weed Management Decisions? Evidence from the Roundup Ready Experiment

Agronomy
Adoption of diverse weed management practices is viewed as essential for slowing the spread of herbicide-resistant (HR) weeds. Yet, adoption of diverse tactics has remained low, while there has been explosive growth of resistant weeds.

Quantifying Adoption Intensity for Weed-Resistance Management Practices and Its Determinants among U.S. Soybean, Corn, and Cotton Farmers

Journal of Agricultural and Resource Economics, 2016
Using data envelopment analysis with principal components, we calculate an adoption-intensity index for herbicide-resistance best management practices (BMPs). Empirical results for over 1,100 farmers in twenty-two U.S.

Dispersal and genetic variability of Sonchus oleraceus L. in relation to its resistance to ALS-inhibiting herbicides.

, 2011
The work described in this thesis investigates the existence and level of acetolactate synthase (ALS)-inhibiting herbicide resistance in Sonchus oleraceus in Australia. It further discusses the sensitivity of different S.

Evaluating Weed Management Programs for the Development of Herbicide Resistance

, 1992
The phenomena of herbicide resistance is not a new concern; triazine resistant weeds were first reported in the late 1960's. Since then, resistance has developed to many other important classes of herbicides.
