The implications of spatially variable pre-emergence herbicide efficacy for weed management [PDF]

, 2017
BACKGROUND The efficacy of pre-emergence herbicides within fields is spatially variable due to soil heterogeneity. We quantified the effect of soil organic matter on the efficacy of two pre-emergence herbicides; flufenacet and pendimethalin, against A.

Biology, Ecology, Distribution and Management of Large Crabgrass (Digitaria sanguinalis)

Weed Research, Volume 65, Issue 4, July/August 2025.
ABSTRACT Digitaria sanguinalis (L.) Scop. (large crabgrass) is a globally distributed annual C4 grass and one of the most challenging weeds in agriculture, causing significant yield losses in crops such as maize, soyabean, rice, cotton and vegetables. This species thrives under favourable and unfavourable conditions such as disturbed soils, fluctuating

Response of Wheat to Pre-Emergence and Early Post-Emergence Herbicides

Agronomy
A two-year field experiment was conducted in two consecutive seasons to evaluate the response of wheat to pre-emergence (PRE) and early post-emergence (EPOST) herbicides.

Control de Bromus, Lolium, Papaver y Avena en cereal de invierno [PDF]

, 2014
Un aspecto fundamental para un control integrado de malas hierbas es conocer la biología de las especies que causan problemas en cada caso. Si se puede prever el momento de su emergencia y se conoce el comportamiento de sus semillas en el suelo y otros ...

Enhanced metabolism causes reduced flufenacet sensitivity in black‐grass (Alopecurus myosuroides Huds.) field populations

Pest Management Science, 2019
ABSTRACTBACKGROUNDBlack‐grass (Alopecurus myosuroides Huds.) is a frequent grass weed that commonly occurs in winter wheat in temperate Europe. Evolving resistance to post‐emergence herbicides, e.g. acetyl CoA carboxylase (ACCase) and acetolactate synthase (ALS) inhibitors requires more complex weed management strategies and ensuring good efficacy of ...

Comparison of a diflufenican-containing premixture to current commercial standards for residual Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus) control

Weed Technology
With Palmer amaranth and waterhemp evolving resistance to nine and six different sites of action (SOAs) globally, soybean producers continue to search for new options to control these problematic weeds.

Current and future management challenges for globally invasive grasses, with special reference to Echinochloa crus‐galli, Panicum capillare and Sorghum halepense

Weed Research, Volume 65, Issue 2, March/April 2025.
Abstract Without appropriate and ongoing management interventions, weeds will continue to economically and environmentally disadvantage agricultural and natural ecosystems. For these management strategies to have long‐term sustained success, they need to carefully consider the biological aspects of the targeted weed.

Investigating the Efficacy of Selected Very-Long-Chain Fatty Acid-Inhibiting Herbicides on Iowa Waterhemp (Amaranthus tuberculatus) Populations with Evolved Multiple Herbicide Resistances

Agronomy, 2021
Very long chain fatty acid (VLCFA)-inhibiting herbicides (Herbicide group (HG) 15) have been applied to corn and soybean fields in Iowa since the 1960s.

Unintentional herbicide resistance in Lolium hybridum and Lolium perenne cultivars and its impact on weedy populations

Weed Research, Volume 65, Issue 2, March/April 2025.
Abstract Ryegrass species (Lolium spp.) are both cultivated crops and troublesome weeds. Weedy ryegrasses are prone to evolve herbicide resistance and are particularly widespread in regions of intense ryegrass propagation, like Saxony in Germany and the Pacific Northwest in the USA.
