The rust fungus, Puccinia komarovii var. glanduliferae has been introduced as a biological control agent, but success has been patchy. Here, we investigated whether mycorrhizal and endophytic fungi can affect rust efficacy and plant growth. Over three experiments, we found that AM fungi and the rust alone or

Minimal soil disturbance combined with spring cropping can halt soil seedbank accumulation of Alopecurus myosuroides Weed Res. (IF 1.7) Pub Date : 2023-03-09 Alexander Menegat
The basic mechanism of soil inversion tillage for control of annual weeds is based on the vertical translocation of weed seeds from the soil surface to deeper soil layers. Buried weed seeds either remain dormant in the soil seedbank and are exposed to biological and chemical decay mechanisms, or they germinate but the seedlings cannot reach the soil surface (fatal germination). However, depending on

Evaluation of finger weeder safety and efficacy for intra-row weed removal in irrigated field crops Weed Res. (IF 1.7) Pub Date : 2023-02-28 Evyatar Asaf, Gal Rozenberg, Itai Shulner, Hanan Eizenberg, Ran Nisim Lati
Increased demand for pesticide-free food and the development of herbicide-resistant weed populations have created a need for non-chemical weed-control tools. A candidate mechanical tool for controlling weeds in the seeding line (intra-row zone) is the finger weeder. This study thus aimed to evaluate the safety and weed-control efficacy of the finger weeder in various irrigated field crops. Eight field

Could the dawn of Level 4 robotic weeders facilitate a revolution in ecological weed management? Weed Res. (IF 1.7) Pub Date : 2023-02-22 Charles N. Merfield
Ecological weed management (EWM) considers that not all non-crop plants cause harm, and that non-harmful species ‘aliae plantae’ should be retained to provide multiple positive benefits. Only plants causing ‘significant harm’ are defined as weeds and should be controlled. However, this is difficult to achieve with current herbicide and mechanical weeding technologies. Robotic weeders may be able to

Spatial modelling indicates Striga seedbank density dependence on rainfall and soil traits in the savannas of northern Nigeria Weed Res. (IF 1.7) Pub Date : 2023-02-13 Kamaluddin T. Aliyu, Abdulrahman Lado, Mohammad A. Hussaini, Alpha Y. Kamara, Anas Sulaiman Musa, Mansur U. Dawaki, Mohammed S. Suleiman, Tasiu T. Bello, Aminu A. Fagge, Halima M. Isa, Hassan Ibrahim
Striga is one of most notorious weeds devastating crop production in the dry savannas of northern Nigeria. The weed attacks most cultivated cereals and legumes with crop losses as high as 100% when no control measure is employed. Studies conducted in the dry savannas of Nigeria indicated that Striga seedbank is strongly related to soil and climate properties. This study was conducted to model Striga

Image-based weed recognition and control: Can it select for crop mimicry? Weed Res. (IF 1.7) Pub Date : 2023-01-16 Guy R. Y. Coleman, Asher Bender, Michael J. Walsh, Paul Neve
As highly adaptable plants, weeds have evolved numerous mechanisms to evade control in agroecosystems. For example, reliance on herbicides has resulted in widespread evolution of resistance in many species. Minimising weed adaptation is a major driver for integrated weed management strategies. Crop mimicry is a notable example of weed adaptation, where weed species evolve to avoid control by mimicking

Invasive African boneseed and a native shrub support similar faunal assemblages in a heavily infested landscape Weed Res. (IF 1.7) Pub Date : 2023-01-16 Emma H. Carlos, Michael A. Weston, Maria Gibson, Anthony R. Rendall
Invasive weeds may provide habitat for wildlife in altered landscapes. We compare fauna within three types of sites in You Yangs Regional Park in central Victoria, Australia, that is, sites with an invasive shrub understory (African boneseed, Chrysanthemoides monilifera subsp. monilifera (DC.) T. Norl.), native shrub understory (snowy mintbush Prostanthera nivea), and sites without an understory (open

Characterisation of Czech arable weed communities according to management and production area considering the prevalence of herbicide-resistant species Weed Res. (IF 1.7) Pub Date : 2023-01-11 Michaela Kolářová, Theresa A. Reinhardt Piskáčková, Luděk Tyšer, Thien T. Hoová
Herbicide resistance is a widespread issue that impacts management of conventional farms, but also has ramifications for the weed community assembly; it is therefore important to see how these species factor into the weed community assembly of farms throughout the countryside. This research analysed species richness and community diversity in 98 field relevés from 48 organic and 50 conventional farms

Strategic tillage in Australian conservation agricultural systems to address soil constraints: How does it impact weed management? Weed Res. (IF 1.7) Pub Date : 2023-01-09 Md Sultan Mia, Gaus Azam, Sina Nouraei, Catherine Borger
In the conservation agricultural systems practised in Australia, cultivation is not commonly utilised for the purpose of weed control. However, occasional use of tillage (strategic tillage) is implemented every few years for soil amelioration, to address constraints such as acidity, water repellence or soil compaction. Depending on the tillage method, the soil amelioration process buries or disturbs

Over the last 30 years, many studies have surveyed weed vegetation on arable land. The ‘Arable Weeds and Management in Europe’ (AWME) database is a collection of 36 of these surveys and the associated management data. Here, we review the challenges associated with combining disparate datasets and explore some of the opportunities for future research that present themselves thanks to the AWME database
