BCPC Weed Review 2012
The 49th Annual BCPC Weed Review will be held at the PGRO Conference Centre, Peterborough, Cambridgeshire on 24 October 2012.
The event starts at 9.30 with registration and refreshments and is scheduled to end at 3.45pm
Outline of Presentations
1: Review of current UK R&D projects on weeds and weed control
Peter Lutman, Rothamsted Research
Funding for weed research has declined in recent years and there is a perception that there is now little independent weed research being done in the UK. Is this true? This presentation will endeavour to collate a list of all the currently funded UK research projects in Universities, Colleges and Research Organisations, funded by government, the EU, levy boards and other private funding organisations. Projects will be organised into appropriate groups to indicate areas of current importance and contact names will be provided for the project leaders.
2: Clearfield: A new approach to broad spectrum weed control in oilseed rape
Jon Williams & Will Reyer, BASF
The Clearfield production system is now available for use by UK oilseed rape growers. The system is a new approach using traditional plant breeding methods and brings a range of benefits to the grower. This session at the BCPC Weed Review will present an overview of the system, with a focus on key features and benefits.
3: Precision guidance weed control in oilseed rape: weeding between the lines
Ron Stobart, NIAB TAG
Effective control of annual grass weeds is essential to maintain rotations of mainly autumn-sown crops. Within these systems oilseed rape remains very important for rotational weed control, however, there is concern over the potential for contamination of water arising from the use of some key active ingredients in the crop (e.g. metazachlor, carbetamide and propyzamide). Carbetamide and propyzamide are particularly important as they are not affected by resistance in black-grass. HGCA research project RD-2009-3605 ‘New approaches to weed control in oilseed rape’ is seeking to evaluate novel approaches to weed control in oilseed rape and explore a range of systems that could be used to effectively deliver weed control to specific areas; this could be only within the inter-row spacing of rape crops or only over the crop row itself. Such approaches could help to minimise reliance on commonly-used selective residual herbicides. In order to achieve this research is looking at a number of delivery techniques (e.g. nozzle types, shrouding and nozzle orientation), positioning systems (e.g. manual, vision-guided and RTK-DGPS based) and weed control methods (e.g. chemical and mechanical). This HGCA research project is being undertaken by SAC, NIAB TAG, Monsanto, Micron Sprayers Ltd, Tillett and Hague Technology Ltd, Garfords Farm Machinery, John Deere and the Organic Research Centre Elm Farm.
4: Bracken control: with or without asulam ?
Simon Thorp, The Heather Trust
The Heather Trust operates throughout the UK from its base in Dumfries. In October last year, Simon was invited to establish a Bracken Control Group and to coordinate the activity of the Group. Such a Group had been under consideration for some time, but the final trigger was the ban on asulam products that comes into full effect at the beginning of 2013. Asulam is the only selective product for the control of bracken and the only product that can be applied by helicopter. These two properties make it an essential part of the efforts made by land managers to control the invasive nature of bracken in the uplands on a large scale. The presentation will provide an overview of the alternative bracken control techniques. The background to the ban on asulam products will be covered together with details of the steps that are being taken to maintain a supply of asulam products from the start of 2013 until re-registration of the product can be achieved. It is clear that there is support for the continued use of asulam products from government and therefore there is room for some optimism that it will still be possible to control bracken on a large scale on steep, broken or inaccessible ground; the presentation will conclude with an assessment of the chances.
5: Control of herbicide-resistant black-grass: current status and future solutions
Richard Hull, Rothamsted Research
2011-2012 has been a tough year for control of pests, with black-grass not being immune to the difficulties. Was the lack of control due to tough environmental conditions, or due to a more worrying increase in resistance? This talk will try and give a few answers to these questions; using the latest results from a recently completed CRD funded black-grass survey and our on-going work on residual herbicides. Also, is the high use of residual chemistry sustainable? The second half of the talk will look at the future solutions for black-grass control in a situation of no new actives. Older chemistries will re appear and of course, there will need to be a greater use of non-chemical control.
6: Bioherbicides: global status and latest results from on-going UK research
An overview of bioherbicide use globally and in the UK will be presented to set the scene. Recent trial results from ongoing UK research as part of the HortLINK funded SCEPTRE project including a range of bioherbicides screened against perennial and annual weeds will be presented.
