Herbicide-resistant weeds: From research and knowledge to future needs

open access: yes, 2013
Synthetic herbicides have been used globally to control weeds in major field crops. This has imposed a strong selection for any trait that enables plant populations to survive and reproduce in the presence of the herbicide.

Economic impacts of high labour cost and herbicide resistance for the management of annual barnyardgrass (Echinochloa crus-galli) in rice production in the Philippines [PDF]

open access: yes
Implications of increasing labour cost and development of herbicide resistance for profitable weed management in Philippine rice farming systems are investigated.

Biodiversity versus transgenic sugar beet : the one Euro question [PDF]

open access: yes, 2002
The decision whether to release transgenic crops in the EU is one subject to flexibility, uncertainty and irreversibility. The case of herbicide tolerant sugar beet is analysed.

Herbicide-free weed management in kharif maize (<i>Zea mays</i> L.) intercropping Systems: Advancing environmental sustainability, productivity, and economic efficiency

open access: yesJournal of Applied and Natural Science
Maize (Zea mays L.), commonly known as the "queen of cereals," is extensively cultivated with wide spacing, facilitating intercropping with legumes to improve productivity and sustainability. Intercropping systems are advantageous for weed management, decreasing dependence on herbicides, and enhancing environmental sustainability.

Investigating the cost of adaptation in Amaranthus tuberculatus populations with evolved resistance to glyphosate [PDF]

open access: yes
Amaranthus tuberculatus (Common Waterhemp) is a prevalent, problematic weed in Midwestern USA, where genetically-modified crops are widely grown, resulting in multiple annual applications of glyphosate.

Glutathione transferases in soybean glycine max (L.) Merr [PDF]

open access: yes, 1999
Glutathione transferases, also known as Glutathione S-transferases (GSTs), are a diverse group of enzymes that catalyse the conjugation of the tri-peptide glutathione to a wide range of electrophilic substrates.

Economic evaluation of a weed-activated sprayer for herbicide application to patchy weed populations [PDF]

open access: yes
Spatial distribution of weeds in a crop is patchy. Traditional boom sprayers waste herbicide by applying it to areas where weed density is already low.

Are no-till herbicide-free cropping systems possible? A simulation study

open access: yes
The aim of this study was to investigate the links between reduced tillage, reduced herbicide use and eeds with surveys and simulations with the FLORSYS model. In the 395 cropping systems identified during farm surveys the herbicide treatment frequency index increased when the frequency of tillage decreased.

Sesame (Sesamum indicum L.) Growth and Yield as Influenced by Preemergence Herbicides

open access: yesInternational Journal of Agronomy, 2012
Studies were conducted during the 2007 and 2008 growing seasons under weed-free conditions in South Texas and the High Plains region of Texas to evaluate preemergence herbicides for sesame tolerance.

Herbicide resistance in rice in Italy: is its evolution associated with agronomic and environmental conditions?

open access: yes, 2017
In North West Italy 200,000 ha are cropped with rice following two different systems: in the NW of the area (Piedmont region), monoculture and water seeding are traditional , while in the SE part (Lombardy region) dry seeding technique and rotation are ...
