Weedy plant species that have evolved resistance to herbicides due to enhanced metabolic
capacity to detoxify herbicides (metabolic resistance) are a major issue. Metabolic herbicide …

Cytochrome P450s (P450s) have been at the center of herbicide metabolism research as a
result of their ability to endow selectivity in crops and resistance in weeds. In the last 20 …

Herbicides are the foundation of weed control in commercial crop-production systems.
However, herbicide-resistant (HR) weed populations are evolving rapidly as a natural …

Modern herbicides make major contributions to global food production by easily removing
weeds and substituting for destructive soil cultivation. However, persistent herbicide …

Acetohydroxyacid synthase (AHAS) inhibitor herbicides currently comprise the largest site‐
of‐action group (with 54 active ingredients across five chemical groups) and have been …

Since its discovery and initial commercialization in the 1940s, 2, 4-D has been an important
tool for weed control in a wide variety of crop and noncrop uses. Work studying its chemistry …

With no major new site-of-action herbicide introduced into the marketplace in the last 20
years, the stagnation or decline in available herbicides in the past decade in a number of …

We have witnessed a dramatic increase in the frequency and diversity of herbicide-resistant
weed biotypes over the past two decades, which poses a threat to the sustainability of …

In input-intensive cropping systems around the world, farmers rarely proactively manage
weeds to prevent or delay the selection for herbicide resistance. Farmers usually increase …

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