Yield performance of imidazolinone-tolerant basmati rice genotypes under dry direct-seeded conditions and its impact on succeeding crops

Frontiers in Sustainable Food Systems
IntroductionWeed management is a major challenge in dry direct-seeded rice (DDSR) systems due to severe weed infestation and limited selectivity of post-emergence herbicides in basmati rice.

Mechanisms and impacts of future plant invasions: research agendas and management needs under disruptive social‐ecological change scenarios

Oikos, EarlyView.
No‐analogue futures are characteristic of the Anthropocene, but how global change, and societies' responses, will affect plant invasions remains unclear. Conducting research now to address future needs is crucial for guiding invasion management and policy.

Herbicide strategies for weed control in Wisconsin conventional-tillage corn production systems

Weed Technology
Selection of effective herbicide strategies (i.e., one-pass versus two-pass and timing [preemergence versus postemergence]) is of great importance to corn growers.

Determination of Phenoxyacetic Herbicide Residues in Biological Materials

Acta Veterinaria Scandinavica, 1966
The development of a method for separating and determining phenoxyacetic herbicide residues in biological materials is described. The sample is extracted with solvent at low pH and the phenoxy acids are separated from coextracted matter by partitioning between solvent and aqueous buffer at pH 6.2 and subsequent thin-layer chromatography.

Globally widespread weeds show preadaptation to non‐analogue climates: a common garden approach

Oikos, EarlyView.
Climatic niche shifts have been documented for plant species introduced into new regions, however the underlying mechanisms are poorly understood. Niche shifts into novel climates are particularly difficult to predict as previous occurrence data cannot reveal whether these novel climates are within species' fundamental niche limits.

Satsuma Orange Tolerance to Spring and Autumn Indaziflam Applications in Georgia

Agriculture
Citrus is a major crop in the SE US, with groves located primarily in Florida, but adapted cultivars have allowed for the expansion of commercial production into the Coastal Plains region of Georgia.

Resilience for restoration: Insights from the Northern Great Plains native seed system

People and Nature, EarlyView.
Abstract Native plants are essential to ecological restoration and culturally important to local and Tribal communities, yet native seed systems across the United States (US) struggle to meet restoration demand. In the US Northern Great Plains, land conversion of native ecosystems means restoration potential is high but constrained by an underdeveloped

Remaking place relations for social‐ecological restoration: Reflections on placemaking in South Africa

People and Nature, EarlyView.
Abstract Ecological restoration is an ongoing relational process involving interconnected reciprocal social and biophysical interactions that shift and change over time and space. Conceptual literature proposes that placemaking can deepen and enhance the understanding and implementation of social‐ecological restoration processes as part of broader ...

Weeds in a changing climate: Competitors or service plants?

PLANTS, PEOPLE, PLANET, EarlyView.
Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...
