Suppression of soil microbiota rather than neighbours facilitates absinthe Artemisia absinthium invasion in native grasslands

Oikos, EarlyView.
Many mechanisms can lead to successful plant invasion, but their importance is often context dependent. One such mechanism is allelopathy: chemical inhibition of neighbouring plants. The importance of allelopathy may be mediated by soil microbiota and environmental conditions, and depend upon the species or functional group affected.

Altered Translocation Pattern as Potential Glyphosate Resistance Mechanism in Blackgrass (Alopecurus myosuroides) Populations from Lower Saxony

International Journal of Plant Biology
Glyphosate is a broad-spectrum herbicide widely used. After years of extensive usage, many weed species have developed resistance due to both target-site (TSR) and non-target-site resistance mechanisms (NTSRs).

Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

Pest Management Science, EarlyView.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

Analysis of glutamine synthetase target‐site mutations and their role in endowing glufosinate‐ammonium resistance

Pest Management Science, EarlyView.
GS2.2 G255D mutation conferred enzyme‐level glufosinate insensitivity but no whole‐plant resistance, showing trade‐offs between catalytic function and herbicide binding and providing a baseline for future studies on target‐site glufosinate resistance.

Low level resistance of goosegrass (Eleusine indica) to glyphosate in Rio Grande do Sul-Brazil [PDF]

Planta Daninha, 2013
In the last growing seasons, goosegrass (Eleusine spp.) control failures have been observed following application of glyphosate on Roundup Ready® soybean in Rio Grande do Sul (RS) - Brazil, suggesting this species' resistance to the herbicide.

Occurrence of Multiple Glyphosate-Resistant Weeds in Brazilian Citrus Orchards

AgriEngineering, 2023
Glyphosate is the most widely used herbicide for weed control in citrus orchards in Brazil; therefore, it is likely that several species have gained resistance to this herbicide and that more than one resistant species can be found in the same orchard ...

Managing pests by increasing predators through late termination of cover crops

Pest Management Science, EarlyView.
Adding cover crops to crop rotations can improve the sustainability and ecosystem functioning of agroecosystems. By delaying cover‐crop termination, growers can effectively increase natural enemy populations and reduce the need for chemical controls. Abstract BACKGROUND Adding cover crops to crop rotations can improve the sustainability and ecosystem ...

Using ecoinformatics to evaluate the impact of crop and herbicide rotations on herbicide intensity

Pest Management Science, EarlyView.
Maize fields with cotton in rotation receive lower herbicide application than fields without cotton. Abstract BACKGROUND Crop rotation is a central component of integrated weed management (IWM) under real‐world conditions, yet its impact on herbicide use remains unclear. To address this challenge, we developed an ecoinformatics‐driven analysis approach

Rootstock impacts on citrus flush dynamics, vegetative growth, and Diaphorina citri infestation and dispersion: Implications for huanglongbing management

Pest Management Science, EarlyView.
Dwarfing citrus rootstocks restrict flush shoot growth on the scion, thereby reducing Asian citrus psyllid infestation, dispersal, and huanglongbing (HLB) progression. These findings support the use of dwarfing rootstocks as an effective cultural strategy in integrated HLB management for citrus orchards.

Distribution of Glyphosate- and Thifensulfuron-Resistant Palmer Amaranth (Amaranthus palmeri) in North Carolina

International Journal of Agronomy, 2014
Glyphosate resistance in Palmer amaranth was first confirmed in North Carolina in 2005. A survey that year indicated 17 and 18% of 290 populations sampled were resistant to glyphosate and thifensulfuron, respectively.
