Framework for an expert evaluation for the evolution of weed resistance [PDF]

Julius-Kühn-Archiv, 2014
The apparent rate of evolution of resistance of weeds to herbicides has increased substantially over the past decade. Data suggests phenotypic expression is affected by the mechanism of action of the herbicide, the taxonomy of the weed, the extent and ...

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

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.

Reduced Translocation Confers Paraquat Resistance in Plantago lanceolata

Agronomy
Ribwort plantain (Plantago lanceolata L.) is a common weed in the winter rainfall region of South Africa. This weed is widespread across vineyards, orchards, and roadsides in the region. The weed has already evolved resistance to glyphosate and paraquat;

Weed Manager-A model-based decision support system for weed management in arable crops [PDF]

, 2009
Weed Manager is a model-based decision support system to assist arable farmers and advisers in weed control decisions on two time scales: within a single season and over several years in a rotation.

Using stochastic dynamic programming to support weed management decisions over a rotation [PDF]

, 2009
This study describes a model that predicts the impact of weed management on the population dynamics of arable weeds over a rotation and presents the economic consequences.

A discussion of the market and policy failures associated with the adoption of herbicide-tolerant crops

International Journal of Agricultural Sustainability, 2019
Weed control in the U.S. Midwest has become increasingly herbicide-centric due to the adoption of herbicide-tolerant (HT) crops in the 1990s. That integrated weed management (IWM) practices, including ecological and mechanical controls, are scarcely used

Emerging Challenges for Weed Management in Herbicide-Resistant Crops

Agriculture, 2019
Since weed management is such a critical component of agronomic crop production systems, herbicides are widely used to provide weed control to ensure that yields are maximized.

Herbicide resistant weeds: the case of resistance to glyphosate

Vietnam Journal of Science, Technology and Engineering, 2022
Glyphosate has become the most widely used herbicide worldwide since 1974 with a global use of 8.6 billion kg (glyphosate active ingredient) between 1974 and 2014.
